How Date Calculations Work
Our date calculator uses the Gregorian calendar, which is the most widely used calendar system in the world today. The Gregorian calendar was introduced by Pope Gregory XIII in 1582 as a reform of the Julian calendar. It accounts for leap years (years divisible by 4, except century years not divisible by 400) to keep the calendar aligned with Earth's orbit around the sun.
