February 29

Unit of Time

February 29, also known as leap day or leap year day, is a date added to most years that are divisible by 4, such as 2016, 2020, and 2024. A leap day is added in various solar calendars, including the Gregorian calendar standard in most of the world. Lunisolar calendars instead add a leap or intercalary month.

*****Why Add a Leap Day?*****

Leap days are needed to keep our calendar in alignment with the Earth's revolutions around the Sun.

It takes the Earth approximately 365.242189 days – or 365 days, 5 hours, 48 minutes, and 45 seconds – to circle once around the Sun. This is called a tropical year.

Without an extra, or intercalary, day on February 29 nearly every four years, we would lose almost six hours every year. After only 100 years, a calendar without leap years would be off by approximately 24 days in relation to fixed seasonal days such as the vernal equinox or the winter solstice.

*****Caesar Introduced Leap Years*****

Roman general Julius Caesar implemented the first leap day in his Julian Calendar, which he introduced in 45 BCE. A leap day was added every four years. At the time, leap day was February 24, and February was the last month of the year.

*****Too Many Leap Years*****

However, adding a leap day every four years was too often and eventually, in 1582, Pope Gregory XIII introduced the Gregorian Calendar. This calendar, which we still use today, has a more precise formula for calculation of leap years, also known as bissextile years.
