# How to determine if a year is a leap year?

A Leap Year has 366 days (the extra day is the 29th of February) whereas a non leap year has 365 days

## Answer: To determine if a year is a leap or not we will check its divisibility with 4, 100 and 400

Let's look into the rules of finding out if a given year is a leap year

## Explanation:

A leap year needs to satisfy the following conditions put together.

- If it is evenly divisible by 4
- Unless it is also evenly divisible by 100
- Unless it is also evenly divisible by 400

Example:

a) 2020 is not a leap year as it is divisible by 4 but not divisible by 100 and 400

b) 2000 is not a leap year though it is divisible by 4 because it is also evenly divisible by 100 and 400 and hence, it does not satisfy the conditions of the leap year.
