Date stuff [Jun. 21st, 2000|03:39 pm]
Brad Fitzpatrick
Heh ... date stuff is interesting:
The Julian calendar defined leap years as every 4th year. The Gregorian calendar improved this by making every 100th year NOT a leap year, unless it was also the 400th year. The Gregorian calendar has been extrapolated back to the year 1000 AD and forward to the year 9999 AD. Note that in historical context, the Julian calendar was in use until 1582 when the Gregorian calendar was adopted by the Catholic church. Protestant countries did not accept it until later; Germany and Netherlands in 1698, British Empire in 1752, Russia in 1918. Note that the Gregorian calendar is itself imperfect. Each year is on average 26 seconds too long, which means that every 3,323 years, a day should be removed from the calendar. No attempt is made to correct for that.
I remember from a tour of some Mayan ruins I went to that the Mayans actually discovered that the year was 365 days, 6 hours, 20 minutes, and 30.56 seconds long .... how's that for accuracy using stones as measuring devices?
