From ancient origins to modern-day superstitions, Leap Year is more than just an extra day on the calendar – it's a captivating journey through time, filled with historical significance, fascinating stories, and surprising discoveries.
Without further ado, let’s jump right in and learn 13 fascinating Leap Year facts that leap to mind on this special day!
What is Leap Year, and How Did Leap Year Start?
The reason for Leap Year’s existence all revolves around the sun—literally.
The concept of Leap Year started when ancient civilisations noticed that the solar year, or the time it takes for the Earth to orbit the Sun, is not exactly 365 days, but rather approximately 365.25 days long.
As a way to synchronise calendars with the Earth's orbit around the sun and stay aligned with the seasons, they added an extra day every few years to compensate for the slight discrepancy.
In fact, the Egyptians were among the first to introduce a Leap Year around 4,000 years ago, based on observations of the stars.
This practice evolved over time through various cultures, with the Romans eventually refining the system by periodically adding an extra month.
Following the Romans, the Leap Year system further evolved with the introduction of the Julian calendar by Julius Caesar in 45 BCE.
This calendar established a rule for Leap Years, adding an extra day to February every four years—The 29th of February, which we now know as Leap Day. However, this system still had some minor inaccuracies.
In 1582, Pope Gregory XIII introduced the Gregorian calendar to address these inaccuracies and better align the calendar with astronomical observations.
It was at this point that the Gregorian calendar refined the Leap Year system by introducing rules that omitted leap years in years that were divisible by 100 but not by 400.
This adjustment ensured a more accurate alignment with the solar year and is the system that we still follow today.

Approximately, as of 2024, there is an astounding 8.1 billion people in the world.

Additionally, the club also aims to raise awareness about Leap Year, sharing personal stories expressing both the benefits and challenges that leaplings face as a result of their unique birthdays.
5. 29 February is traditionally considered a day on which women are allowed to propose to men.
According to ancient tradition, a woman is allowed to propose to a man on 29 February.
This custom has been allegedly attributed to various historical figures; However, one specific theory, although widely disputed, is said to have involved St. Bridget during the 5th century.
As the story goes, St. Bridget was said to have complained to St. Patrick that women were forced to wait too long for their suitors to propose. In response, St. Patrick supposedly granted women one day in which they were allowed to pop the question to their lovers—Leap Day.
Another theory for the basis of this tradition goes back to the time when Leap Day was not recognised in English law. Because the day had no legal status, it was therefore deemed acceptable for women to break the convention of men proposing and take marital matters into their own hands.
Finally, one other popular theory of this custom stems from Queen Margaret of Scotland. In this version of the story, Queen Margaret, only 5 years old at the time, declared in 1288 that a woman had permission to propose to any man she fancied on 29 February.
6. Men may even be fined for not accepting a woman’s marriage proposal on Leap Day!
According to the theory attributing the tradition of women proposing on Leap Day to Queen Margaret of Scotland, Queen Margaret also ruled that men who turned down a woman’s proposal would be forced to pay a fine in one of the following forms—a silk dress, a kiss, a pair of gloves, or one pound.
However, Scotland is not the only country in which a woman’s heartbreak caused by a declined marriage proposal on Leap Day comes with a steep price.
In Denmark, if a man refuses a woman’s proposal on Leap Day, he must gift her with a dozen pairs of gloves.
In Finland, the fine a man must pay is enough fabric to make a skirt.
It turns out that it’s true what they say—Love does come with a price.
7. In some cultures, 29 February is deemed an unlucky day.
Although Leap Year is often considered to be a fun and unique occurrence to be celebrated for many, Leap Year isn’t always received with the same enthusiasm all over the world.
In fact, in some cultures, Leap Year is actually considered to be bad luck.
For example, in Scotland, Leap Year is believed to be bad for livestock, which is the reason why the Scottish are known to say, “Leap Year was ne’er a good sheep year.”
In Italy, a common saying surrounding Leap Year is “anno bisesto, anno funesto,” which translates to “leap year, doom year.”
Due to this, Italians are warned against planning special activities such as weddings, supporting this superstition with the saying, “anno bisesto tutte le donne senza sesto,” which translates to, “In a Leap Year, women are erratic.”
Similarly, it is reported that 1 in 5 engaged couples in Greece intentionally avoid getting married in a Leap Year because they believe that it is bad luck.
8. There are twin towns known as “Leap Year Capitals of the World.”
On the flip side, there are two self-proclaimed “Leap Year Capitals of the World”—the twin towns of Anthony, Texas, and Anthony, New Mexico—who pride themselves on throwing a giant birthday bash every Leap Year to celebrate leaplings visiting from all over the world.
The Leap Year festival is a huge and exciting affair, with the event’s duration lasting an appropriate 4 days.
9. Many people will work for free on 29 February.
As they say, there’s no rest for the weary.
Because their wages are most likely not calculated to include the extra day on a Leap Year, most employees with fixed annual salaries will essentially work for free on 29 February.
10. Technically speaking, Leap Year isn’t always every four years.
Julius Caesar's idea had merit, yet his calculations fell slightly short; the additional day every four years proved to be an excessive adjustment.
Consequently, there is a Leap Year if the year is divisible by four.
However, here’s the catch.
To be eligible as a Leap Year, century years (ending in 00) must also be divisible by 400. This means that the year 2000 was a leap year, while 1700, 1800, and 1900 were not.
11. Disclosing birthday information may be more of a hassle for leapers, as 29 February is often not recognised as a valid day.
Apparently, being so special sometimes comes with a price.
Unfortunately, due to their unusual circumstances, leapers may have to leap over hurdles to receive official recognition of their birthday.
Many companies, businesses, government documentation, medical records, and technology systems do not acknowledge Leap Day as a “valid day.”
For example, some drop-down menus used to input your birth date do not include 29 February as a choice. Birthday loyalty programs can also get tricky, as systematically, there may not be a way to recognise Leap Year birthdays during non-Leap Years.
Furthermore, even if there is an option to input 29 February, leapers may be questioned about their selected birthday, as some tend to think that it was chosen by mistake.
In response to these hassles, many leapers have no choice but to list their birthdays as either 28 February or 1 March.

13. Leap Year babies are the only ones who have really found the key to the fountain of youth.
Leapers stay forever young because technically speaking, their birthdays only occur once every four years.
That means that they will always be one-fourth of the age of their counterparts who were born in the same year as them on any day other than Leap Day.
This is why if you happen to ask a middle-aged looking leapling how old they are, you shouldn’t be surprised if they cheekily answer, “12 years old.”
In fact, the record age for the oldest Leap Year baby to have ever lived lingers at 27 years old, which translates to 110 years for someone who was not born on Leap Day.
A big happy birthday to all of our beloved leaplings!
