Formula:
A year is considered a leap year if it satisfies the following criteria, as per the Gregorian calendar rules:
- It is evenly divisible by 4 (e.g., 2024, 2028).
- However, if it is a century year (a year ending in '00', e.g., 1900, 2000), it must also be evenly divisible by 400 to be a leap year.
- If a century year is divisible by 4 but not by 400, it is not a leap year (e.g., 1900 was not a leap year, but 2000 was).
Our calculator applies these rules to give you an instant result.
