Question

Why do we follow Leap Year?

Answer 1

During leap years, a leap day is added to the calendar to slow down and synchronize the calendar year with the seasons. Leap days were first added to the Julian Calendar in 46 B.C. by Julius Caesar at the advice of Sosigenes, an Alexandrian astronomer.

Answer 2

Answer:

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 ¼ 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.
