Operations such as comparing two times, +calculating a time a given amount of time from another, or parsing +international times are all easily done. + +Date::Manip deals only with the Gregorian calendar (the one currently in +use). 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. |
