What is a leap year?

Planet Earth, like other planets, exhibits two primary movements: rotation and revolution.

Rotation is the spinning of the Earth on its axis.
The Earth's axis is an imaginary line passing through the poles, inclined at almost 24 degrees.
A complete rotation takes 24 hours, equivalent to one day.
Rotation causes day and night, with the side facing the sun experiencing daylight and the opposite side experiencing night.

Revolution is the movement of the Earth around the sun.
One complete revolution takes one year.
The Earth's orbit around the sun is elliptical, not cyclical.
Revolution and the inclination of the Earth's axis lead to the four seasons: spring, summer, autumn, and winter.
When a hemisphere is more inclined towards the sun, it receives more direct sunlight, resulting in warmer temperatures and summer, while the opposite hemisphere experiences winter.
In six months, the seasons reverse as the Earth continues its revolution.

The Earth's revolution around the sun takes 365 days and 6 hours, not exactly 365 days.
To account for the extra hours, leap years occur every four years, adding one day (February 29th) to the year, making it 366 days long.
A leap year calculation saved Earth from an asteroid impact in the example.
