Why do we have a leap year?

Best Answers

Nearly every four years, we add an extra day to the calendar in the form of February 29, also known as Leap Day. Put simply, these additional 24 hours are built into the calendar to ensure that it stays in line with the Earth's movement around the Sun. read more

Nearly every four years is a leap year which has 366 days, as opposed to a common year, which has 365 in the Gregorian Calendar. Leap years have 366 days, not 365. We use leap years to sync our common years with the tropical years. read more

The name "leap year" probably comes from the fact that while a fixed date in the Gregorian calendar normally advances one day of the week from one year to the next, the day of the week in the 12 months following the leap day (from March 1 through February 28 of the following year) will advance two days due to the extra day (thus "leaping over" one of the days in the week). read more

Our calendar has 365 days in a year, because that's pretty much how long it takes the Earth to orbit the Sun. The problem is that in reality it takes the Earth around 365 ΒΌ days (actually 365.24219 days) to circle the Sun (that's a solar year), which means our calendar is out by around a quarter of a day a year. read more
