History of the Gregorian calendar

The Gregorian calendar is internationally the most widely used civil calendar. It is named after Pope Gregory XIII, who introduced it in October 1582. The calendar spaces leap years to make the average length of the calendar year (365.2425 days) closer to the length of the tropical year (365.2422 days). It was a modification of the Julian calendar. The motivation for the Gregorian reform was to solve the issue of the calendar drifting further away from the equinoxes and solstices—particularly the winter solstice—which occurs on December 22 or 23, on the Julian calendar.

What is the Julian calendar?

The Julian calendar was introduced by Julius Caesar in 45 BC, making it the oldest verified calendar in existence. It was the first calendar to have leap years. It was used by the Roman Empire, and many countries around the world continue to use the calendar. A leap year is every year divisible by four. The Julian calendar is a solar calendar, meaning that it is based on the position of the earth in relation to the sun.
