What are leap years?

The Gregorian calendar is the system which serves as the standard calendar around the world.
It boasts both common years, and leap years, with the latter comprising of 365 days.
The latter, of course, includes an extra day.
A leap year takes place every four years.

Why do we need leap years?

The extra day in leap years is designated at the end of the second month: February 29.
A leap year occurs to help synchronise the calendar year with the solar year, or in other words, the length of time it takes the Earth to complete its orbit around the sun.

Explain more.

Right.
The length of time it takes the Earth to complete its orbit around the sun is 365¼ days, but the length of the solar year is slightly less than this.
In fact, it's less by about 11 minutes.
To compensate for this discrepancy, a leap year is omitted three times every four centuries.
