Do we skip leap years?
We actually skip a leap year if it falls on the start of a century. For example 1700, 1800, and 1900 were not leap years despite being divisible by 4. But if that that century year is divisible by 400, we do have a leap year. … That brings the error down to only 26 seconds too much each year.

To eliminate this error, the Gregorian calendar stipulates that a year that is evenly divisible by 100 (for example, 1900) is a leap year only if it is also evenly divisible by 400. This is because they are evenly divisible by 100 but not by 400. This is because they are evenly divisible by both 100 and 400.

A year may be a leap year if it is evenly divisible by 4. Years that are divisible by 100 (century years such as 1900 or 2000) cannot be leap years unless they are also divisible by 400. (For this reason, the years 1700, 1800, and 1900 were not leap years, but the years 1600 and 2000 were.)
