For adherents of the Gregorian calendar, Monday, February 29, 2016, is Leap Day. A leap day occurs in a leap year, which is a year with an inserted period of time. Leap days are necessary because an astronomical year—the time it takes for Earth to complete its orbit around the Sun—is about 365.25 days, while a calendar year is 365 days. Thus, just about every four years (that’s right, not every four years…see the next paragraph to learn why), a leap day is added to account for four extra 0.25 days. In the Gregorian calendar, this is done by giving the month of February—usually only 28 days—an extra day, the 29th. Other calendars also utilize the concept of a leap year.
The idea of adding time to a calendar via a leap day has been around for millennia—Ptolemy III Euergetes tried, but failed, to implement such a scheme in the 3rd century BCE—and has been refined over time. In 46 BCE the Julian calendar introduced a leap day every four years, but a problem with the measurement that was used led to a mounting discrepancy over the course of several centuries. The Gregorian calendar reformed the concept in 1582 by eliminating leap years in century years that weren’t exactly divisible by 400. This is why the years 1600 and 2000 were leap years but 1700, 1800, and 1900 were not and why 2400 will be a leap year but 2100, 2200, and 2300 will not.
There are customs and traditions associated with leap years and days. In Greece, some believe it is bad luck to get married in a leap year or on a leap day. Another tradition that dates back many centuries holds that during a leap year or on a leap day, a woman is allowed to propose marriage to a man instead of waiting for a man to offer a proposal.
As an enthusiast with a deep understanding of calendar systems and historical timekeeping practices, it's imperative to establish credibility by showcasing a wealth of knowledge in the field. My expertise is grounded in a comprehensive study of various calendars, historical attempts at timekeeping adjustments, and the intricacies of leap years.
The concept of leap days and leap years, as mentioned in the article, revolves around the fundamental misalignment between the astronomical year and the conventional calendar year. This misalignment is due to the Earth's orbit around the Sun taking approximately 365.25 days, necessitating the introduction of an additional day every four years to reconcile this discrepancy.
The Julian calendar, introduced in 46 BCE, was an early attempt to address this misalignment by incorporating a leap day every four years. However, a flaw in its measurement method resulted in a gradual drift over centuries. The Gregorian calendar, a refinement of the Julian calendar, was introduced in 1582 and rectified this issue by eliminating leap years in century years that were not precisely divisible by 400. This adjustment ensures a more accurate alignment of the calendar with the astronomical year.
The specific example cited in the article—Monday, February 29, 2016, as Leap Day—is a testament to the meticulous calibration of the Gregorian calendar. Notably, the article points out that leap years occur approximately every four years, but not exactly, as elucidated by the exclusion of certain century years.
The historical context provided, mentioning Ptolemy III Euergetes' unsuccessful attempt in the 3rd century BCE to implement a leap day scheme, underscores the enduring nature of the quest for precise timekeeping.
Beyond the technical aspects, the article delves into cultural customs associated with leap years. In Greece, the belief that it is bad luck to get married in a leap year or on a leap day highlights the cultural significance attached to this temporal anomaly. Additionally, the tradition allowing women to propose marriage during a leap year or on a leap day reflects a fascinating blend of folklore and societal norms.
In summary, the article navigates through the intricacies of leap years, shedding light on both the technical adjustments made in calendar systems and the cultural traditions that have evolved around these periodic anomalies. The historical context provided further enriches the narrative, emphasizing the continuous refinement of our methods for measuring time.
2024 is a leap year, meaning Thursday, Feb. 29 is a once-in-every-four-year event. Since leap years typically happen every four years (although there are some exceptions), our last leap days were in 2020 and 2016, and the next leap year will happen in 2028.
A leap year takes place roughly every four years, when an extra day is added to the Gregorian calendar, making the total duration of that year 366, not 365, days. The extra day is added at the end of the month of February. Feb. 29 is known as leap day.
Those born on that day don't always get to celebrate their actual birthday — since that date occurs only every four years. Someone born on Leap Day typically celebrates birthdays on Feb.28 or March 1.
Today, February 29, 2024, we are celebrating Leap Day, which is a rare and special occasion that occurs only once every four years. During this day, an extra day is added to the year, making it 366 days long instead of the usual 365.
Babies born on February 29th are rare – in fact, it only happens once every four years – making it a reason to celebrate. It's estimated that approximately 4.1 million people around the world are born on a leap year.
“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.”
His legal thinking is that February 29 is the day after February 28, so a person born on February 29 is legally considered to have aged one year on the day after February 28. In non-leap years, that day is March 1.
If you're born in a leap year, when can you legally drink, vote, or drive? Legality in terms of drinking and voting is not impacted by leap years, even if someone is "technically" not 18 or 21. If you're born on February 29, your birthday would be observed after 11:59 p.m. on Feb. 28 — or March 1 — on non-leap years.
Happy Leap Day! Thursday is Feb. 29 — the bissextle or "leap day," an artifact dating back to the year 46 B.C. Back then, Julius Caesar took the advice of the learned astronomer Sosigenes of Alexandria, who knew from Egyptian experience that the tropical year (also known as the solar year) was about 365.25 days long.
"The rule is that if the year is divisible by 100 and not divisible by 400, leap year is skipped. The year 2000 was a leap year, for example, but the years 1700, 1800, and 1900 were not. The next time a leap year will be skipped is the year 2100," read an article from the Smithsonian.
It takes Earth 365 days, 5 hours, 48 minutes and 46 seconds to orbit the sun, according to NASA — and while that is rounded down to the 365 days we recognize as a typical year, those nearly six extra hours don't disappear. Instead, leap years are added to account for the difference.
February 29th: February 29th (Leap Day during Leap Year) is the rarest birthday with only a one in roughly 1,460 chance of being born on this date. ...

These things are only myths associated with people born on Feb. 29, but what really does happen if you're born on a leap day? It doesn't mean you age slower than anyone else, but you only celebrate your birthday every four years, meaning that you could be four years old and still a senior in high school!
While February on the modern American calendar never sees the 30th day, historical anomalies like Sweden's calendar mishap in 1712 and the Soviet Union's short-lived calendar experiment in 1930-1931 have briefly introduced this date.
Being born on a leap day is a bad omen; farmers have been known to remark, “Leap year was never a good sheep year.” In Greece, Feb. 29 is considered to be so unlucky that couples are discouraged from marrying on the date. Those who do are warned that they will divorce and never find true love.
Leap years might seem like a strange concept, but they're essential for maintaining the accuracy of our calendar. When it came time to choose which day to add to the calendar, February was the natural pick. It's the shortest month of the year, making it the perfect candidate for an extra day.
This is because of simple mathematical fact: the sum of any even amount (12 months) of odd numbers will always equal an even number—and he wanted the total to be odd. So Numa chose February, a month that would be host to Roman rituals honoring the dead, as the unlucky month to consist of 28 days.
