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.
