About the Gregorian calendar
The calendar most of the world uses today was introduced in 1582 by Pope Gregory XIII to correct a slow drift in the older Julian calendar. The Julian year was 365.25 days; the actual tropical year is 365.2422 days. That eleven-minute discrepancy added up over centuries — by 1582 the calendar had drifted ten days off the seasons. The Gregorian reform skipped those days (October 4 was followed directly by October 15) and changed the leap-year rule: years divisible by 100 are no longer leap years, unless they are also divisible by 400.
Adoption was slow and uneven. Catholic countries switched in 1582; Britain and its colonies waited until 1752; Russia held out until 1918. Some Eastern Orthodox churches still use the Julian calendar for religious feasts, which is why Orthodox Christmas falls on January 7.
