Question

(3)Why do leap year comes every four years?

Answer 1

Answer:

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.

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.

Answer 2

Answer:

A leap year occurs every four years to help synchronize the calendar year with the solar year, or the length of time it takes to complete the Earth's orbit around the sun, which is about 365 days and a quarter of a day. The length of the solar year, however, is slightly less than 365 days-by about 11 minutes.
