The Gregorian calendar is considered the most accurate calendar in use today. It was introduced by Pope Gregory XIII in 1582 and is a refinement of the Julian calendar. It reduces the average year from 365.25 days to 365.2425 days, aligning more closely with the solar year. This accuracy is achieved by having a leap year every four years, except for years that are divisible by 100 but not by 400, which are not leap years.
