Motions of the Earth
Leap year
Our Earth takes 365 days and 6 hours to complete
one revolution. We usually count 365 days
in a year and 6 hours is
left . But this 6 hours in
every year becomes 24
hours . 24 hours means
One day.
So every four
year is a leap year.
A leap has 366 days instead of 365 days.
One day is added to Feb
ruary. So February has
29 days instead of 28days in aleap year.
In leap year there are 366
Days and February has
29 days. A leap year is
always divisible by 4.
2020 is a leap year because it is divisible by
4.
