Question

Why we have a leap year after every 4 year please answer
​

Answer 1

Answer: This may help you

Explanation:

There is a leap day every 4 years because Earth completes one revolution around the sun in around 365 days and 6 hours. Over a period of 4 years, the extra 6 hours from every year get added up to become an entire day (6*4=24 hours). Hence, we have a leap day/leap year every 4 years.

It takes 365.25 days for Earth to orbit around the Sun — a solar year. We usually round the days in a calendar year to 365. To make up for the missing partial day, we add one day to our calendar approximately every four years. That is a leap year.
