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.
