Leap year calculator checks if a given year is a leap year or not. It follows certain rules such as: a leap year is divisible by 4, unless it is divisible by 100, unless it is divisible by 400.

How **leap year calculator** works

The leap year calculator is an algorithm that determines whether a given year is a leap year or not by applying specific rules. According to these rules: a year is a leap year if it is divisible by 4, unless it is divisible by 100, unless it is divisible by 400. By entering a year, the calculator verifies and provides an output indicating whether it is a leap year or not. Consequently, it streamlines and enhances the accuracy of manually computing leap years.

A leap year is a year that contains an additional day, February 29th, to keep the calendar year synchronized with the solar year. The solar year, which is the amount of time it takes for the Earth to complete one orbit around the sun, is about 365.2425 days. To keep the calendar year aligned with the solar year, an extra day is added every four years.

The rules to determine if a year is a leap year are as follows:

1. If a year is **evenly divisible by 4**, it is a leap year.

2. However, if a year is **evenly divisible by 100**, it is not a leap year, unless...

3. The year is also **evenly divisible by 400**, in which case it is a leap year.

Here are some examples of leap years in the past and future:

2000 (divisible by 400)

1996 (divisible by 4 but not by 100)

1992 (divisible by 4 but not by 100)

1988 (divisible by 4 but not by 100)

1984 (divisible by 4 but not by 100)

2020 (divisible by 4 but not by 100)

2024 (divisible by 4 but not by 100)

2028 (divisible by 4 but not by 100)

2032 (divisible by 4 but not by 100)

2036 (divisible by 4 but not by 100)
