A calendar is a system of organizing days for social, religious, commercial, or administrative purposes. The Gregorian calendar is the most widely used calendar in the world today. It was introduced in 1582 by Pope Gregory XIII as a reform of the Julian calendar. The Julian calendar had been in use for over 1,600 years, but it had become inaccurate because it was not synchronized with the Earth’s orbit around the sun.

The Gregorian calendar is a solar calendar, which means that it is based on the Earth’s orbit around the sun.
