Introduction

A leap year (in the Gregorian calendar) occurs:

  • In every year that is evenly divisible by 4.
  • Unless the year is evenly divisible by 100, in which case it's only a leap year if the year is also evenly divisible by 400.

Some examples:

  • 1997 was not a leap year as it's not divisible by 4.
  • 1900 was not a leap year as it's not divisible by 400.
  • 2000 was a leap year!
