Question

Why does leap year happens every 4 yrs

Answer 1

Leap year occurs every because each year actually has 365 days and 6hrs. So what we do is we eliminate each of the six hours of 3 years and add it to the fourth year. That is 6hrs+6hrs+6hrs+6hrs(fourth year's )which equals to 24 hrs or a day. We add this day to the fourth year(365+1 days)or leap year which has 366 days. Hope it helped you

Answer 2

Answer:

leap year happens every 4 year because earth takes 365 days and 6 hours to complete 1 revolution. 1 day = 24 hrs . 6 * 4 = 24 hrs , that is why 1 day is added to every 4th year and that year is known as leap year
