Leap years in the Taiwan calendar correspond to the same leap years in the Gregorian calendar. A leap year in the Gregorian calendar is defined as a Gregorian year that is evenly divisible by four, except if it is divisible by 100. However, Gregorian years that are divisible by 400 are leap years. A common year has 365 days and a leap year has 366 days.

A leap month is an entire month that occurs only in a leap year. The Taiwan calendar does not have any leap months.

The following example calls IsLeapMonth for all the months in five years in the current era.
