How this is calculated

  • Dates use Eastern Time (America/New_York). Remaining-year counts exclude the reference date and include December 31. Weeks remaining are full seven-day blocks, with remaining days shown separately.
  • Gregorian leap years are divisible by 4, except century years unless divisible by 400.

How to use the leap-year calculator

Enter any year to check whether it is a leap year with a February 29.

Example

2024 and 2028 are leap years. 2100 is not, because century years must be divisible by 400; 2000 was a leap year.

Common questions

What is the leap year rule?
A year is a leap year if it is divisible by 4, except century years, which must also be divisible by 400.
