How the Leap Year Calculator Works
This calculator illustrates how leap years affect the number of days between two dates. It calculates the total number of days like a standard calculator but is especially useful for understanding time spans where the presence of a February 29th is a factor.

The underlying formula is the same as a standard days-between-dates calculator, which inherently accounts for the extra day in leap years.
