What is leap year (366 days)?

In the Gregorian calendar, the internationally accepted civil calendar, the leap years are the years exactly divisible by four. For example, the year 2000 is a leap year while the year 2001 is not a leap year.

In the leap years, the month of February has 29 days instead of 28 days. Thus, the leap years have 366 days, one day more than the common years. The extra day in the leap year (i.e., the 29th day of February) is called the leap day. The Gregorian calendar omits 3 leap days every 400 years.
