The Gregorian Calendar

The Gregorian Calendar, introduced by Pope Gregory XIII in 1582, is the calendar most widely used today. It improved upon the Julian Calendar by correcting inaccuracies in the tracking of the solar year. The Gregorian system divides the year into 12 months totaling 365 days, with a leap year adding an extra day every four years to keep it aligned with the Earth’s orbit around the Sun. This calendar helps standardize timekeeping for civil, commercial, and religious purposes and is essential for managing seasons, agriculture, and daily life worldwide.
