When did the first calendar ever begin and does it ever end?

Question

Like, when was the first year the calendar begin?

Answer 1

In western European history, there have been two calendars, the Julian and the Gregorian. The Julian calendar is so called because it was promulgated by Julius Caesar when he was pontifex maximus (high priest) of the Roman state religion about 50 BC.

It was not quite accurate, and by the 1500's, people noticed that the seasons were slightly out of joint. Vatican astronomers came up with the more accurate calendar that we use today, in which February has 29 days in every leap year, except years that are evenly divisible by 400, like 1600 and 2000, which were not leap years.

In the mid-1500's, the Vatican adopted the new calendar named after a Pope Gregory of that day. To do it, they dropped 11 days, just as we drop an hour when we go on daylight savings time in the spring. Protestant countries did not go along, nor did countries where the Greek or Russian Orthodox churches had a say.

The American colonies adopted the Gregorian calendar in the mid-1700's. At the time of the Bolshevik coup during the Russian revolution in 1917, the Russians were on the Julian calendar and westerners on the Gregorian. So the "Ten Days that Shook the World" occurred in late October according to the Russians abnd early November according to westerners. Hence the film, "The Hunt for Red October."

Answer 2

First Calendar Ever

Answer 3

The Chinese, the Indians, and the Jewish people all have very old calenders, but I doubt that we will ever determine who invented the idea.

As long as there are people to measure time, any calender need never end
