# How to tell if a year is a leap year

## Question: How to tell if a year is a leap year?

Let us understand the concept of the leap year.

## Answer: If the year is having 366 days or if the year is divisible by 4, then we can tell that year is a leap year.

Let us understand the rule in detail.

## Explanation:

A normal year consists of 365 days in fact 365.25 days. For calculation and daily convention, we consider 365 days per year.

0.25-day x 4 = 1 day, so 1 day will be added every 4 years.

So, we get a leap year consisting of 365 + 1 = 366 days once in 4 years.

So, a leap year consists of 366 days.

As it comes every 4 years, if the year is divisible by 4, then it is a leap year.

Example 2020, 1992, 1996 are leap years whereas 2018, 1991, 2021 are not leap years.

### Hence, if the year is having 366 days or if the year is divisible by 4, then we can tell that year is a leap year.
