2: An Alternative Days Per Month Reckoning | This version creates a 364-day Calendar (371 days for Leap Year) |
January, April, July and October ................ 30 days each. 1st day of each month is Monday February, May, August and November ....... 31 days each. 1st of each month is Wednesday March, June, September and December .... 30 days each. 1st day of each month is Saturday Regular Year - 364 days ... 52 7-day weeks Leap Year - 371 days ... 53 7-day weeks Halves - 182 / 182 days Quarters - 91 / 91 / 91 / 91 days Each week begins on a Monday, ends on a Sunday -- No chance ever of a Friday the 13th !! Leap Year, 371 days long with a 7-day "Leap Week" between June 30th and July 1st, is any year that ends in "0" or "5", with the following exceptions ... (1) Any years ending in "25" or "75" (2) Any Century Years divisible by 400 (1600, 2000, 2400, 2800, etc.), which of course is the exact opposite of the actual Gregorian system. In any given 400-year period, there are 329 364-day regular years (119,756 days) and 71 371-day Leap Years (26,341 days). This makes for a total of 146,097 days (exactly 20,871 7-day weeks) during any given 400-year period. Remarkably, the figures of 146,097 days and 20,871 weeks are an -EXACT MATCH- to the days and weeks within any 400-year period of the Gregorian Calendar !!! Example of the Special 364/371-day calendar (opens in a new window/tab) SPECIAL NOTE The author of this web-site (frankosite2020.com - where you are now) is not the only one who has proposed this particular method of 364/371-day calendar reckoning. See the Symmetry 010 Calendar and the Symmetry 454 Calendar for more details. |
3: The 4000-Year Rule
It has been suggested by some observers, including the astronomer John Herschel (1792-1871), that a better approximation to the length of the tropical year would be 365 969/4000 days = 365.24225 days. This would dictate 969 leap years every 4000 years, rather than the 970 leap years currently mandated by the Gregorian calendar. This could be achieved by not observing Leap Year and February 29th every 4,000 years -- 4000 A.D., 8000 A.D., 12000 A.D., 16000 A.D. and so on. To date, this "4000-year rule" has not been officially adopted. |
