What Is a Leap Year Calculator?
A Leap Year Calculator is an online date tool that checks if a given year contains 366 days instead of the usual 365 days.
Leap years occur because the Earth’s orbit around the Sun takes approximately 365.2422 days, not exactly 365 days. The extra day helps keep our calendar aligned with the Earth’s seasons.

Using the Leap Year Calculator is simple:
- Enter a year.
