The following general rule for finding the date of commencement of any Mohammedan year has a maximum error of a day: Multiply 970, 224 by the Mohammedan year, point off six decimal places, and add 621.5774. The whole number will be the year The Mohammedan calendar is one of the most primitive. It is strictly a Lunar calendar, the year consisting of twelve lunar months, which retrograde through the seasons in about 321/2 years. To reconcile the lunar cycle to a given number of complete days, a leap year is introduced on the 2nd, 5th, 7th, 10th, 13th, 16th, 18th, 21st, 24th, 26th and 29th years of a thirty year cycle, making these years consist of 355 days instead of 354. The names of the months and the number of days are: 1, Muharram (30); 2, Saphar (29); 3, Rabia I (30); 4, Rabia II (29); 5, Jomada I (30); 6, Jomada II (29); 7, Rajah (30); 8, Shaaban (29); 9, Ramadan (30); 10, Shawaal (29); 11, Dulkasda (30); and 12, Dulheggia (29 or 30). The years are calculated from July 16, 622 A.D., the day following the Hegira, the flight of Mohammed from Mecca to Medina after an attempted assassination. The beginning of the 46th cycle, with the first day of Muharram, in the year 1351, compares to May 7, 1932 of the Gregorian calendar; continuing: 1365 Dec. 6, 1945 1366 Nov. 25, 1946 1367 Nov. 15, 1947 1368 Nov. 3, 1948 1369 Oct. 24, 1949 1370 Oct. 13, 1950 1371 Oct. 2, 1951 1372 Sept. 21, 1952 1373 Sept. 10, 1953 1374 Aug. 30, 1954 To find the Gregorian equivalent to any Mohammedan date multiply 970, 224 by the Mohammedan year, point off six decimal places and add 621.5774. The whole number will be the year A.D., and the decimal multiplied by 365 will be the day of the year. https://web.archive.org/web/20040112151506/http://www.arsakeio.gr/universe/timeref1.htm [ PJC ] |
