The Gregorian calendar is today's internationally accepted civil calendar and is also known as the Western or Christian calendar.

It did not properly reflect the actual time it takes the Earth to circle once around the Sun, known as a tropical year.
The Gregorian Calendar is the most widely used calendar in the world today.
It is a solar calendar based on a 365-day common year divided into 12 months of irregular lengths.
Eleven of the months have either 30 or 31 days, while the second month, February, has only 28 days during the common year.
Also every four years a day is include on 29 February which is making the leap year in the Gregorian calendar.
So Gregorian Calendar is having 366 days in leap year.
