What Is the Gregorian Calendar?

The Gregorian Calendar is the most widely used calendar system in the world today. It is based on the movements of the Sun and is therefore also known as the Solar Calendar. A year consists of 365 days and 6 hours. Every four years, these extra 6 hours accumulate to form an additional day, creating a “leap year” in which the month of February has 29 days.
