Every fourthyear is a leap year, as a rule of thumb. But that's not the end of the story. A year that is divisible by 100, but not by 400, is not. So 2000 was a leap year under the Gregorian calendar, as was 1600. But 1700, 1800 and 1900 are not leap years.
Leap years  occur on years that are exactly divisible by four (with no  remainder), with the exception of most century (â¦also called  centenary) years. Only century years divisible by 400 are leap years.  For instance, even though 1900 is divisible by four (1900/4 equals  475), 1900 was not a leap year.
