A precise tool.
What is the Leap Year Calculator & How does it work?
A leap year is a year that is exactly divisible by 4 except for century years (years ending with 00). The century year is a leap year only if it is perfectly divisible by 400. For example, the year 2000 was a leap year, although 1900 was not.This rule ensures that the calendar remains synchronized with the solar year, which is approximately 365.24219 days long.

Frequently Asked Questions
How do I check if a year is a leap year?
A year is a leap year if it’s divisible by 4, but not every century year is. Century years are only leap years if they’re divisible by 400.
Is the year 2000 a leap year?
Yes, the year 2000 was a leap year because it’s divisible by 400.
Why is 1900 not a leap year?
The year 1900 is not a leap year because it’s a century year (ends in 00) and isn’t divisible by 400.
Can you explain the rules for determining a leap year?
A year is a leap year if it’s divisible by 4. However, if it’s also a century year (ends in 00), it must be divisible by 400 to be considered a leap year.
What is the purpose of having leap years?
Leap years help keep our calendar aligned with the Earth’s revolutions around the Sun, ensuring that seasons occur at the same time each year.
