BOSTON — Four years after the COVID-19 pandemic closed schools and upended child care, the CDC says parents can start treating the virus like other respiratory illnesses.

Gone are mandated isolation periods and masking. But will schools and child care centers agree?

In case you’ve lost track: Before Friday, all Americans, including school children, were supposed to stay home for at least five days if they had COVID-19 and then mask for a set period of time, according to the Centers for Disease Control and Prevention.

Now, with COVID deaths and hospitalizations dropping, the CDC says children can go back to school when their overall symptoms improve and they’re fever-free for 24 hours without taking medication. Students are “encouraged” to wear a mask when they return.

Still, the change may not affect how individual schools urge parents to react when their children fall sick. Schools and child care providers have a mixed record on following CDC recommendations and often look to local authorities for the ultimate word. And sometimes other goals, such as reducing absences, can influence a state or district’s decisions.

The result can be a confusing array of policies among states and districts, not to mention workplaces — confounding parents whose lives have long been upended by the virus.

“This is so confusing,” said Gloria Cunningham, a single mom in the Boston area. “I just don’t know what I should think of COVID now. Is it still a monster?”

Cunningham, who manages a local store for a national restaurant chain, said her company requires her to take off 10 days if she gets COVID-19. And the school system where her son is in second grade has still been sending home COVID test kits for kids to use before returning to school after long breaks.

“I feel like we should just do away with anything that treats COVID differently or keep all of the precautions,” she said.

The public education system has long held varying policies on COVID. During the 2021-22 school year, only 18 states followed CDC recommendations for mask-wearing in class. When the CDC lifted its masking guidelines in February of 2022, states like Massachusetts followed suit, but California kept the mask requirement for schools.

And in the child care world, some providers have long used more stringent testing and isolation protocols than the CDC has recommended. Reasons have ranged from trying to prevent outbreaks to keeping staff healthy — both for their personal safety and to keep the day care open.

Some states moved to more lenient guidelines ahead of the CDC. California and Oregon recently rescinded COVID-19 isolation requirements, and many districts followed their advice.

In an attempt to minimize school absences and address an epidemic of chronic absenteeism, California has encouraged kids to come to school when mildly sick and said that students who test positive for coronavirus but are asymptomatic can attend school. Los Angeles and San Diego’s school systems, among others, have adopted that policy.

But the majority of big-city districts around the country still have asked parents to isolate children for at least five days before returning to school. Some, including Boston and Atlanta, have required students to mask for another five days and report positive COVID-19 test results to the school.

Some school leaders suggest the CDC’s previous five-day isolation requirement was already only loosely followed.

Official policy in Burlington, Massachusetts, has been to have students stay home for five days if they test positive. But Superintendent Eric Conti said the real policy, in effect, is: “It’s a virus. Deal with it.”

That’s because COVID is managed at home, using the honor system.

“Without school-based testing, no one can enforce a five-day COVID policy,” he said via text message.

Ridley School District in the Philadelphia suburbs was already using a policy similar to the new CDC guidelines, said Superintendent Lee Ann Wentzel. Students who test positive for COVID must be fever-free without medication for at least 24 hours before returning to school. When they come back, they must mask for five days. Wentzel said the district is now considering dropping the masking requirement because of the new CDC guidance.

A school or day care’s specific guidelines are consequential for working parents who must miss work if their child can’t go to school or child care. In October 2023, during simultaneous surges of COVID, respiratory syncytial virus and influenza, 104,000 adults reported missing work because of child care issues, the highest number in at least a decade. That number has fallen: Last month, child care problems meant 41,000 adults missed work, according to the Bureau of Labor Statistics.

Melissa Colagrosso’s child care center in West Virginia dropped special guidelines for COVID about a year ago, she said. Now, they’re the same as other illnesses: A child must be free of severe symptoms such as fever for at least 24 hours before returning to the center.

“We certainly are treating COVID just like we would treat flu or hand, foot and mouth” disease, said Colagrosso, CEO of A Place To Grow Children’s Center in Oak Hill.

As for kids without symptoms who test positive for COVID? Most parents have stopped testing kids unless they have symptoms, Colagrasso said, so it’s a quandary she has not encountered.

Still, some parents worry the relaxed rules put their communities at greater risk. Evelyn Alemán leads a group of Latino and Indigenous immigrant parents in Los Angeles County. The parents she represents, many of whom suffer from chronic illnesses and lack of access to health care, panicked when California did away with isolation requirements in January.

“I don’t think they’re considering what the impact will be for our families,” she said of California officials. “It feels like they don’t care – that we’re almost expendable.”

Other impacts of the pandemic linger, too, even as restrictions are lifted. In Ridley, the Philadelphia-area district, more students are reclusive and struggle to interact in-person with peers, said Wentzel, the superintendent. Interest in school dances has plummeted.

“Emotionally,” Wentzel said, “they’re having trouble.”

MOANDA, DR Congo — The oil drills that loom down the road from Adore Ngaka’s home remind him daily of everything he’s lost. The extraction in his village in western Congo has polluted the soil, withered his crops and forced the family to burn through savings to survive, he said.

Pointing to a stunted ear of corn in his garden, the 27-year-old farmer says it’s about half the size he got before oil operations expanded nearly a decade ago in his village of Tshiende.

“It’s bringing us to poverty,” he said.

Congo, a mineral-rich nation in central Africa, is thought to have significant oil reserves, too. Drilling has so far been confined to a small territory on the Atlantic Ocean and offshore, but that’s expected to change if the government successfully auctions 30 oil and gas blocks spread around the country. Leaders say economic growth is essential for their impoverished people, but some communities, rights groups and environmental watchdogs warn that expanded drilling will harm the landscape and human health.

Since the French-British hydrocarbon company, Perenco, began drilling in Moanda territory in 2000, residents say pollution has worsened, with spills and leaks degrading the soil and flaring — the intentional burning of natural gas near drilling sites — fouling the air they breathe. And the Congolese government exerts little oversight, they say.

Perenco said it abides by international standards in its extraction methods, that they don’t pose any health risks and that any pollution has been minor. The company also said it offered to support a power plant that would make use of the natural gas and thus reduce flaring. The government did not respond to questions about the proposed plant.

Congo’s minister overseeing oil and gas, Didier Budimbu, said the government is committed to protecting the environment.

Congo is home to most of the Congo Basin rainforest, the world’s second-biggest, and most of the world’s largest tropical peatland, made up of partially decomposed wetlands plant material. Together, both capture huge amounts of carbon dioxide — about 1.5 billion tons a year, or about 3% of global emissions. More than a dozen of the plots up for auction overlap with protected areas in peatlands and rainforests, including the Virunga National Park, which is home to some of the world’s rarest gorillas.

The government said the 27 oil blocks available have an estimated 22 billion barrels. Environmental groups say that auctioning more land to drill would have consequences both in Congo and abroad.

“Any new oil and gas project, anywhere in the world, is fueling the climate and nature crisis that we’re in,” said Mbong Akiy Fokwa Tsafak, program director for Greenpeace Africa. She said Perenco’s operations have done nothing to mitigate poverty and instead degraded the ecosystem and burdened the lives of communities.

Environmental activists said Congo has strong potential to instead develop renewable energy, including solar, as well as small-scale hydropower. It’s the world’s largest producer of cobalt, a key component for batteries in electric vehicles and other products essential to the global energy transition, although cobalt mining comes with its own environmental and human risks.

Budimbu said now is not the time to move away from fossil fuels when the country is still reliant on them. He said fossil fuel dependency will be phased out in the long term.

Rich in biodiversity, Moanda abuts the Mangrove National Park — the country’s only marine protected area. Perenco has been under scrutiny for years, with local researchers, aid groups and Congo’s Senate making multiple reports of pollution dating back more than a decade. Two civil society organizations, Sherpa and Friends of the Earth France, filed a lawsuit in 2022 accusing Perenco of pollution caused by the oil extraction; that suit is still pending.

During a rare visit by international media to the oil fields, including two villages near drilling, The Associated Press spoke with dozens of residents, local officials and rights organizations. Residents say drilling has inched closer to their homes and they have seen pipes break regularly, sending oil into the soil. They blame air and ground pollution for making it hard to cultivate crops and causing health problems such as skin rashes and respiratory infections.

They said Perenco has responded quickly to leaks and spills but failed to address root problems.

AP journalists visited drilling sites, some just a few hundred meters from homes, that had exposed and corroding pipes. They also saw at least four locations that were flaring natural gas, a technique that manages pressure by burning off the gas that is often used when it is impractical or unprofitable to collect. AP did not see any active spill sites.

Between 2012 and 2022 in Congo, Perenco flared more than 2 billion cubic meters of natural gas — a carbon footprint equivalent to that of about 20 million Congolese, according to the Environmental Investigative Forum, a global consortium of environmental investigative journalists. The group analyzed data from Skytruth, a group that uses satellite imagery to monitor threats to the planet’s natural resources.

Flaring of natural gas, which is mostly methane, emits carbon dioxide, methane and black soot and is damaging to health, according to the International Energy Agency.

In the village of Kinkazi, locals told AP that Perenco buried chemicals in a nearby pit for years and they seeped into the soil and water. They displayed photos of what they said were toxic chemicals before they were buried and took reporters to the site where they said they’d been discarded. It took the community four years of protests and strikes before Perenco disposed of the chemicals elsewhere, they said.

Most villagers were reluctant to allow their names to be used, saying they feared a backlash from a company that is a source of casual labor jobs. Minutes after AP reporters arrived in one village, a resident said he received a call from a Perenco employee asking the purpose of the meeting.

One who was willing to speak was Gertrude Tshonde, a farmer, who said Perenco began dumping chemicals near Kinkazi in 2018 after a nearby village refused to allow it.

“People from Tshiende called us and asked if we were letting them throw waste in our area,” Tshonde said. “They said the waste was not good because it spreads underground and destroys the soil.”

Tshonde said her farm was behind the pit where chemicals were being thrown and her cassava began to rot.

AP could not independently verify that chemicals had been buried at the site.

Perenco spokesperson Mark Antelme said the company doesn’t bury chemicals underground and that complaints about the site near Kinkazi were related to old dumping more than 20 years ago by a predecessor company. Antelme also said Perenco hasn’t moved operations closer to people’s homes. Instead, he said, some communities have gradually built closer to drilling sites.

Antelme also said the company’s flaring does not release methane into the atmosphere.

Perenco said it contributes significantly to Moanda and the country. It’s the sole energy provider in Moanda and invests about $250 million a year in education, road construction, training programs for medical staff and easier access to health care in isolated communities, the company said.

But residents say some of those benefits are overstated. A health clinic built by Perenco in one village has no medicine and few people can afford to pay to see the doctor, they said.

And when Perenco compensates for oil leak damages, locals say it’s not enough.

Tshonde, the farmer, said she was given about $200 when an oil spill doomed her mangoes, avocado and maize eight years ago. But her losses were more than twice that. Lasting damage to her land from Perenco’s operations has forced her to seek other means of income, such as cutting trees to sell as charcoal.

Many other farmers whose land has been degraded are doing the same, and tree cover is disappearing, she said.

Budimbu, the minister of hydrocarbons, said Congo’s laws prohibit drilling near homes and fields and oil operators are required to take the necessary measures to prevent and clean up oil pollution. But he didn’t specify what the government was doing in response to community complaints.

Congo has struggled to secure bidders since launching the auction in July 2022. Three companies — two American and

one Canadian — moved on three methane gas blocks in Lake Kivu, on the border with Rwanda. The government said in May that they were about to close those tenders, but did not respond to AP’s questions in January about whether those deals were finalized.

There are no known confirmed deals on the 27 oil blocks, and the deadline for expressions of interest has been extended through this year. Late last year, Perenco withdrew from bidding on two blocks in the province near where it currently operates. The company didn’t respond to questions from AP about why it withdrew, but Africa Intelligence reported that Perenco had found the blocks to have insufficient potential.

Perenco also didn’t respond when asked whether it was pursuing any other blocks.

Environmental experts say bidding may be slow because the country is a hard place to operate with rampant conflict, especially in the east where violence is surging and where some of the blocks are located.

Local advocacy groups say the government should fix problems with Perenco before bringing in other companies.

“We first need to see changes with the company we have here before we can trust other(s),” said Alphonse Khonde, the coordinator of the Group of Actors and Actions for Sustainable Development.

Congo also has a history of corruption. Little of its mineral wealth has trickled down in a country that is one of the world’s five poorest, with more than 60% of its 100 million people getting by on less than $2.15 a day, according to the World Bank.

And some groups have criticized what they see as lack of transparency on the process of offering blocks for auction, which amounts to “local communities being kept in the dark over plans to exploit their lands and resources,” said Joe Eisen, executive director of the Rainforest Foundation UK.

Some communities where the government has failed to provide jobs and basic services say they have few options but to gamble on allowing more drilling.

In Kimpozia village, near one of the areas up for auction, some 150 people live nestled in the forest without a school or hospital. Residents must hike steep hills and travel on motorbike for five hours to reach the nearest health clinic and walk several hours to school. Louis Wolombassa, the village chief, said the village needs road-building and other help.

“If they come and bring what we want, let them drill,” he said.

CAPE CANAVERAL, Florida — The first U.S. spacecraft to land on the moon since the Apollo astronauts fell silent Thursday, a week after breaking a leg at touchdown and tipping over near the lunar south pole.

Intuitive Machines’ lander, Odysseus, lasted longer than the company anticipated after it ended up on its side with hobbled solar power and communication.

The end came as flight controllers received one last photo from Odysseus and commanded its computer and power systems to standby. That way, the lander can wake up in another two to three weeks — if it survives the bitterly cold lunar night.

Intuitive Machines spokesman Josh Marshall said these final steps drained the lander’s batteries and put Odysseus “down for a long nap.”

“Good night, Odie. We hope to hear from you again,” the company said via X, formerly Twitter.

Before losing power, Odysseus sent back what Intuitive Machines called “a fitting farewell transmission.”

Taken just before touchdown, the picture shows the bottom of the lander on the moon’s pockmarked surface, with a tiny crescent Earth and a small sun in the background.

The lander was originally intended to last about a week on the moon.

Houston-based Intuitive Machines became the first private business to land a spacecraft on the moon without crashing when Odysseus touched down February 22. Only five countries had achieved that since the 1960s, including Japan, which made a sideways landing last month.

Odysseus carried six experiments for NASA, which paid $118 million for the ride. The first company to take part in NASA’s program for commercial lunar deliveries never made it to the moon; its lander came crashing back to Earth in January.

NASA views these private landers as scouts that will pave the way for astronauts set to arrive in another few years.

Until Odysseus, the last U.S. moon landing was by Apollo 17’s Gene Cernan and Harrison Schmitt in 1972.

new york — Older U.S. adults should roll up their sleeves for another COVID-19 shot, even if they got a booster in the fall, U.S. health officials said Wednesday.

The Centers for Disease Control and Prevention said Americans 65 and older should get another dose of the updated vaccine that became available in September — if at least four months has passed since their last shot. In making the recommendation, the agency endorsed guidance proposed by an expert advisory panel earlier in the day.

“Most COVID-19 deaths and hospitalizations last year were among people 65 years and older. An additional vaccine dose can provide added protection … for those at highest risk,” CDC Director Dr. Mandy Cohen said in a statement.

The advisory panel’s decision came after a lengthy discussion about whether to say older people “may” get the shots or if they “should” do so. That reflects a debate among experts about how necessary another booster is and whether yet another recommendation would add to the public’s growing vaccine fatigue.

Some doctors say most older adults are adequately protected by the fall shot, which built on immunity derived from earlier vaccinations and exposure to the virus itself. And preliminary studies so far have shown no substantial waning in vaccine effectiveness over six months.

However, the body’s vaccine-induced defenses tend to fade over time, and that happens faster in seniors than in other adults. The committee had recommended COVID-19 booster doses for older adults in 2022 and 2023.

Virus still a threat

COVID-19 remains a danger, especially to older people and those with underlying medical conditions. There are still more than 20,000 hospitalizations and more than 2,000 deaths each week due to the coronavirus, according to the CDC. And people 65 and older have the highest hospitalization and death rates.

Some members of the advisory panel said a “should” recommendation is meant to more clearly prod doctors and pharmacists to offer the shots.

Dr. Jamie Loehr, a committee member and family doctor in Ithaca, New York, said that with the “should” recommendation, “I am trying to make it easier for providers to say, ‘Yes, we recommend this.'”

In September, the government recommended a new COVID-19 shot recipe built against a version of the coronavirus called XBB.1.5. That single-target vaccine replaced combination shots that had been targeting both the original coronavirus strain and a much earlier omicron version.

Vaccine uptake has declined

The CDC recommended the new shots for everyone 6 months and older and allowed that people with weak immune systems could get a second dose as early as two months after the first.

Most Americans haven’t listened. According to the latest CDC data, 13% of U.S. children have gotten the shots and about 22% of U.S. adults have. The vaccination rate is higher for adults 65 and older, at nearly 42%.

“In each successive vaccine, the uptake has gone down,” said Dr. David Canaday, a Case Western Reserve University infectious-diseases expert who studies COVID-19 in older people.

“People are tired of getting all these shots all the time,” said Canaday, who does not serve on the committee. “We have to be careful about over-recommending the vaccine.”

But there is a subset of Americans — those at higher danger of severe illness and death — who have been asking if another dose is permissible, said Dr. William Schaffner, a Vanderbilt University vaccines expert who serves on a committee workgroup that has been debating the booster question.

Indeed, CDC survey data suggest that group’s biggest worry about the vaccine is whether it’s effective enough.

Agency officials say that among those who got the latest version of the COVID-19 vaccine, 50% fewer will get sick after they come into contact with the virus compared with those who didn’t get the fall shot.

washington — U.S. President Joe Biden’s is a “healthy, active, robust 81-year-old male who remains fit to successfully execute the duties of the presidency,” his physician, Dr. Kevin O’Connor, said in a statement released by the White House on Wednesday, following Biden’s annual physical examination. 

“The president feels well, and this year’s physical identified no new concerns. He continues to be fit for duty and fully executes all of his responsibilities without any exemptions or accommodations,” O’Connor said following Biden’s visit to Walter Reed National Military Medical Center in Bethesda, Maryland, earlier Wednesday.  

The checkup included consultations with optometry, dentistry, orthopedics, physical therapy, neurology, sleep medicine, cardiology, radiology and dermatology specialists, O’Connor said.  

It’s Biden’s third physical since taking office, amid concerns about his age as he seeks a second term.  

“They think I look too young,” Biden joked to reporters at the White House after his checkup. “There is nothing different than last year,” he said.

According to the summary, Biden is currently being treated for several conditions, including obstructive sleep apnea, gastroesophageal reflux, seasonal allergies, arthritis and sensory peripheral neuropathy of the feet. He also has atrial fibrillation with normal ventricular response, a type of asymptomatic irregularity of the heartbeat.  

His doctor pronounced his conditions as “stable and well-controlled,” with “three common prescription medications and three common over-the-counter medications.”  

The symptoms were similar to those described in Biden’s 2023 physical exam report that noted the president’s “stiff gait,” due to “a combination of significant spinal arthritis, mild post-fracture foot arthritis and a mild sensory peripheral neuropathy of the feet,” and “occasional symptoms of gastroesophageal reflux,” that made him have to clear his throat often.     

President didn’t undergo cognitive test 

Recent events have highlighted Biden’s potential age-related issues, including the president being described in a special counsel report as an “elderly man with a poor memory.”      

In pushing back on reporters’ questions about his age, Biden insisted that his “memory is fine” but shortly after mistakenly referred to Egyptian President Abdel Fattah el-Sissi as the president of Mexico. That and two other mistaken references to world leaders’ names in recent weeks fueled further attacks by his rivals.     

Responding to reporters’ questions during her briefing on Wednesday, White House press secretary Karine Jean-Pierre said Biden did not undergo a cognitive test as part of his physical because the president’s physician, “doesn’t believe that he needs one.” 

As president, Biden passes a cognitive test “every day,” Jean-Pierre underscored. 

A poll by the George Washington University shows 35% of respondents say Biden was in good enough physical health to serve effectively as president, and 38% said he has the mental soundness to serve effectively as president.  

This is lower that what respondents say about the leading candidate for the Republican presidential nomination, Donald Trump, who is four years younger. For Trump, the numbers are 54% and 46%, respectively. 

“These figures indicate that this is a big problem for Biden,” Todd Belt, professor of politics at George Washington University, told VOA. “The campaign has changed course to attack Trump on his vulnerabilities on the mental soundness issue.” 

Biden did exactly that during an appearance on a late-night television show earlier this week, by referencing a video in which Trump appeared to forget his wife’s name.  

Americans concerned about Biden’s age

Trump was 70 when he took office in 2017, which made him the oldest American president to be inaugurated until Biden broke his record at 78 in 2021. The former president has also made blunders, including praising Hungarian Prime Minister Viktor Orban for his leadership of Turkey, and confusing his Republican rival, Nikki Haley, with former U.S. House Speaker Nancy Pelosi.   

A February ABC News/Ipsos poll conducted after the release of the special counsel report indicated concerns among 59% of Americans regarding the age and capability for a second term for both candidates, although more Americans are worried about Biden compared with Trump, said Clifford Young, president of Ipsos Public Affairs.   

“Age is an Achilles’ heel, is an anchor for Biden,” Young told VOA. “It was four years ago. Without a doubt, it will be this year.”   

Though not publicly announced in advance, the timing of Biden’s physical was anticipated, given the increasing focus on his age and health in the context of his reelection campaign ahead of the November election.

WASHINGTON — Democrats on Wednesday failed in an attempt to rush legislation through the U.S. Senate guaranteeing Americans’ access to in vitro fertilization and other assisted reproductive technologies, after an Alabama court designated frozen embryos as children.

The state Supreme Court ruling on February 16 that frozen embryos should be considered children prompted at least three Alabama providers to halt the IVF procedure that involves combining eggs and sperm in a laboratory dish for couples having difficulty conceiving.

Alabama’s court ruling has raised concerns that those involved in IVF could face prosecution because embryos that are found to be nonviable are sometimes disposed of or used for research, and that it could encourage other states to follow suit.

Democratic Senator Tammy Duckworth, an Iraq War veteran who suffered grave injuries in combat in 2004, sought an immediate vote by the Senate on Wednesday on passage of her “Access to Family Building Act” legislation.

Her move for a vote, which required the consent of all 100 senators, was promptly blocked by Republican Senator Cindy Hyde-Smith.

“The bill before us today is a vast overreach that is full of poison pills that goes way too far, far beyond ensuring legal access to IVF,” Hyde-Smith said.

Duckworth countered that her bill simply would guarantee access to IVF treatments and facilities “without fear of being prosecuted,” while also shielding IVF providers and health insurance companies.

While many Republican officeholders have expressed discomfort with the Alabama court ruling, the party was not ready to fall in line with Democrats on this hot-button issue that is linked to the national debate over women’s right to abortion.

Duckworth told reporters on Tuesday that she struggled for a decade with infertility following her military service in Iraq, which prompted her and her husband to turn to IVF. They now have two children.

“I have five embryos that were created (using IVF); three that were deemed to be nonviable, would not survive,” Duckworth said.

She said that at the time, in 2013, her doctor told her that if “personhood laws” regarding embryos were to be enacted, “I could be convicted of manslaughter or murder for discarding these three eggs that were nonviable.”

Reproductive rights are expected to be a major issue in this year’s presidential and congressional campaigns, with Democrats lashing out at both the U.S. Supreme Court’s 2022 ruling overturning its landmark Roe v. Wade case establishing a national right to abortion, as well as subsequent state reproductive rights actions such as the one on IVF.

In a statement Wednesday, White House spokesperson Karine Jean-Pierre said the Republican blocking of Duckworth’s measure was “outrageous.”

Jean-Pierre added that President Joe Biden and Vice President Kamala Harris “will continue to fight to protect access to reproductive health care, including IVF, and call on Congress to restore the protections of Roe v. Wade in federal law for all women in every state.”

NEW YORK — Leap year. It’s a delight for the calendar and math nerds among us. So how did it all begin and why?

Have a look at some of the numbers, history and lore behind the (not quite) every four-year phenom that adds a 29th day to February.

By the numbers

The math is mind-boggling in a layperson sort of way and down to fractions of days and minutes. There’s even a leap second occasionally, but there’s no hullabaloo when that happens.

The thing to know is that leap year exists, in large part, to keep the months in sync with annual events, including equinoxes and solstices, according to the Jet Propulsion Laboratory at the California Institute of Technology.

It’s a correction to counter the fact that Earth’s orbit isn’t precisely 365 days a year. The trip takes about six hours longer than that, NASA says.

Contrary to what some might believe, however, not every four years is a leaper. Adding a leap day every four years would make the calendar longer by more than 44 minutes, according to the National Air & Space Museum.

Later, on a calendar yet to come (we’ll get to it), it was decreed that years divisible by 100 not follow the four-year leap day rule unless they are also divisible by 400, the JPL notes. In the past 500 years, there was no leap day in 1700, 1800 and 1900, but 2000 had one. In the next 500 years, if the practice is followed, there will be no leap day in 2100, 2200, 2300 and 2500.

Still with us?

The next leap years are 2028, 2032 and 2036.

What would happen without a leap day?

Eventually, nothing good in terms of when major events fall, when farmers plant and how seasons align with the sun and the moon.

“Without the leap years, after a few hundred years we will have summer in November,” said Younas Khan, a physics instructor at the University of Alabama at Birmingham. “Christmas will be in summer. There will be no snow. There will be no feeling of Christmas.”

Who came up with leap year?

The short answer: It evolved.

Ancient civilizations used the cosmos to plan their lives, and there are calendars dating back to the Bronze Age. They were based on either the phases of the moon or the sun, as various calendars are today. Usually they were “lunisolar,” using both.

Now hop on over to the Roman Empire and Julius Caesar. He was dealing with major seasonal drift on calendars used in his neck of the woods. They dealt badly with drift by adding months. He was also navigating many calendars starting in many ways in the vast Roman Empire.

He introduced his Julian calendar in 46 BCE. It was purely solar and counted a year at 365.25 days, so once every four years an extra day was added. Before that, the Romans counted a year at 355 days, at least for a time.

But still, under Julius, there was drift. There were too many leap years! The solar year isn’t precisely 365.25 days! It’s 365.242 days, said Nick Eakes, an astronomy educator at the Morehead Planetarium and Science Center at the University of North Carolina in Chapel Hill.

Thomas Palaima, a classics professor at the University of Texas at Austin, said adding periods of time to a year to reflect variations in the lunar and solar cycles was done by the ancients. The Athenian calendar, he said, was used in the fourth, fifth and sixth centuries with 12 lunar months.

That didn’t work for seasonal religious rites. The drift problem led to “intercalating” an extra month periodically to realign with lunar and solar cycles, Palaima said.

The Julian calendar was 0.0078 days (11 minutes and 14 seconds) longer than the tropical year, so errors in timekeeping still gradually accumulated, according to NASA. But stability increased, Palaima said.

The Julian calendar was the model used by the Western world for hundreds of years. Enter Pope Gregory XIII, who calibrated further. His Gregorian calendar took effect in the late 16th century. It remains in use today and, clearly, isn’t perfect or there would be no need for leap year. But it was a big improvement, reducing drift to mere seconds.

Why did he step in? Well, Easter. It was coming later in the year over time, and he fretted that events related to Easter like the Pentecost might bump up against pagan festivals. The pope wanted Easter to remain in the spring.

He eliminated some extra days accumulated on the Julian calendar and tweaked the rules on leap day. It’s Pope Gregory and his advisers who came up with the really gnarly math on when there should or shouldn’t be a leap year.

“If the solar year was a perfect 365.25 then we wouldn’t have to worry about the tricky math involved,” Eakes said.

What’s the deal with leap year and marriage?

Bizarrely, leap day comes with lore about women popping the marriage question to men. It was mostly benign fun, but it came with a bite that reinforced gender roles.

There’s distant European folklore. One story places the idea of women proposing in fifth century Ireland, with St. Bridget appealing to St. Patrick to offer women the chance to ask men to marry them, according to historian Katherine Parkin in a 2012 paper in the Journal of Family History.

Nobody really knows where it all began.

In 1904, syndicated columnist Elizabeth Meriwether Gilmer, aka Dorothy Dix, summed up the tradition this way: “Of course people will say … that a woman’s leap year prerogative, like most of her liberties, is merely a glittering mockery.”

The pre-Sadie Hawkins tradition, however serious or tongue-in-cheek, could have empowered women but merely perpetuated stereotypes. The proposals were to happen via postcard, but many such cards turned the tables and poked fun at women instead.

Advertising perpetuated the leap year marriage game. A 1916 ad by the American Industrial Bank and Trust Co. read thusly: “This being Leap Year day, we suggest to every girl that she propose to her father to open a savings account in her name in our own bank.”

There was no breath of independence for women due to leap day.

Being born in a leap year on a leap day certainly is a talking point. But it can be kind of a pain from a paperwork perspective. Some governments and others requiring forms to be filled out and birthdays to be stated stepped in to declare what date was used by leaplings for such things as drivers’ licenses, whether Feb. 28 or March 1.

Technology has made it far easier for leap babies to jot down their Feb. 29 milestones, though there can be glitches in terms of health systems, insurance policies and with other businesses and organizations that don’t have that date built in.

There are about 5 million people worldwide who share the leap birthday out of about 8 billion people on the planet. Shelley Dean, 23, in Seattle, Washington, chooses a rosy attitude about being a leapling. Growing up, she had normal birthday parties each year, but an extra special one when leap years rolled around. Since, as an adult, she marks that non-leap period between Feb. 28 and March 1 with a low-key “whew.”

This year is different.

“It will be the first birthday that I’m going to celebrate with my family in eight years, which is super exciting, because the last leap day I was on the other side of the country in New York for college,” she said. “It’s a very big year.”
