Gregorian CalendarIn 1752, today was the last day of the Julian calendar in Great Britain, Ireland and the British colonies, including those on the East coast of America. Eleven days were skipped to adopt the Gregorian calendar, designed to realign the calendar with equinoxes. Hence the following day was 14 Sep. For more than a century and a half before, following the decree by Pope Gregory XIII, Italy, and three other Catholic countries (Spain, Portugal and Poland) used the Julian calendar for the last time on 4 Oct 1582. France followed, ending Julian calendar use on 9 Dec 1582. Russia did not change until the early 20th century: 31 Jan 1918 was the last Julian date, followed the next day by 14 Feb 1918. Parts of China changed in 1912, but the Communist revolution, 1949, established Gregorian calendar use in all China.« |
