In this latest installment of "Interesting but useless trivia," we look at the roots of the calendar system that we go by.
|Pope Gregory XIII instituted the Gregorian calendar system.|
Prior to the Gregorian calendar, the Julian calendar, introduced by Julius Caesar in 46 BC, had been the dominant civil calendar used in the world, and, in fact, the Julian calendar was, according to an article on timeanddate.com, “...still used by some countries into the early 1900s. Some Orthodox churches still use it today to calculate the dates of moveable feasts, such as the Orthodox Church in Russia. Others who still use the Julian calendar include the Berber people of North Africa and on Mount Athos.”
Today, the difference between the two calendars is now at 13 days, with the Julian calendar trailing behind the Gregorian. The main difference between the two calendars has to do with calculating leap years. The Julian calendar has too many leap years, and so the goal of the Gregorian is to correct this and provide for a more accurate calendar.
