A leap year occurs every four years when an additional day, February 29th, is added to the calendar to synchronize it with the solar year. This extra day compensates for the fact that Earth's orbit around the sun actually takes about 365.2425 days, not precisely 365 days.
Feb. 29 has traditionally been a day on which women were allowed to propose to men.
Sounds hopelessly outdated for the 21st century, but this is the way it has worked in many cultures for centuries!
There are two “Leap Year Capitals of the World.”
If you want to celebrate this special day in a big way, head to Texas — or New Mexico. Anthony, Texas and Anthony, New Mexico both claim the title “Leap Year Capital,” while holding lavish, multi-day celebrations each leap year.
Lots of people work for free on Feb. 29.
Most employees who are paid fixed monthly incomes will work for free on Feb. 29 because their wages are likely not calculated to include the extra day.
Feb. 29 is not really a legal day.
Many companies don’t recognize Leap Day as a “valid day.” They make leapers choose
Feb. 28 or March 1 as their birthday instead.
Julius Caesar introduced the first calendar leap year in 46 B.C.
The Earth takes exactly 365 days, five hours, 48 minutes and 45 seconds to circle the sun. The occasional Feb. 29 ensures we don’t lose six hours every year.

Here are some facts about leap years:
- Julian and Gregorian calendars: The concept of leap years dates back to the Julian calendar, introduced by Julius Caesar in 45 BCE. It initially had a simple rule: add a leap day every four years. However, this resulted in a slight inaccuracy, which was later adjusted in the Gregorian calendar reform in 1582 by Pope Gregory XIII.
- Leap year rule: In the Gregorian calendar, a leap year occurs every year divisible by 4, except for years that are both divisible by 100 and not divisible by 400. For instance, 1900 was not a leap year because, while divisible by 4 and 100, it wasn't divisible by 400. But the year 2000 was a leap year.
- History: The idea of intercalating days to sync the calendar with astronomical events can be traced back to various ancient civilizations, including the Egyptians and the Babylonians. The need for this adjustment has been recognized for millennia.
- Mathematical precision: The Gregorian system is highly accurate, with an average year length of 365.2425 days, bringing it very close to the actual solar year of about 365.2422 days. This small difference means that over centuries, slight adjustments are still needed, but they're minimal.
