That is interesting! Of interest, the Gregorian calendar hasn't been in use all that long> The Gregorian calendar is the one commonly used today. It was proposed by Aloysius Lilius, a physician from Naples, and adopted by Pope Gregory XIII in accordance with instructions from the Council of Trent (1545-1563) to correct for errors in the older Julian Calendar. It was decreed by Pope Gregory XIII in a papal bull in February 1582. In the Gregorian calendar, the tropical year is approximated as 365 97/400 days = 365.2425 days. Thus it takes approximately 3300 years for the tropical year to shift one day with respect to the Gregorian calendar. The important effects of the change were: Drop 10 days from October 1582, to realign the Vernal Equinox with 21 March. Change leap year selection so that not all years ending in "00" are leap years. Change the beginning of the year to 1 January from 25 March. C = Y/100, N = Y - 19(Y/19), K = (C - 17)/25, I = C - C/4 - (C - K)/3 + 19N + 15, I = I - 30(I/30), I = I - (I/28)(1 - (I/28)(29/(I + 1))((21 - N)/11)), J = Y + Y/4 + I + 2 - C + C/4, J = J - 7(J/7), L = I - J, M = 3 + (L + 40)/44, D = L + 28 - 31(M/4). The legal code of the United States does not specify an official national calendar. Use of the Gregorian calendar in the United States stems from an Act of Parliament of the United Kingdom in 1751, which specified use of the Gregorian calendar in England and its colonies. The Gregorian calendar today serves as an international standard for civil use. In addition, it regulates the ceremonial cycle of the Roman Catholic and Protestant churches. In fact, its original purpose was ecclesiastical. Although a variety of other calendars are in use today, they are restricted to particular religions or cultures.
