How many days are there in Leap Year?
Leap year=366 days. (2020,2024,2028….)
February lasts neither 30 nor 31. February is normally 28 days. However, it lasts 29 days once in every 4 years. This distinction is because of a year keeps going 356 days and 6 hours. In the event that the additional six hours a year will be ignored, the schedule would move 25 days in like clockwork. Since these additional 6 hours are equivalent to 24 hours in like clockwork, they are incorporated into February. This is the reason February keeps going 29 days once in at regular intervals.
