When did a circle get divided into 360 degrees?

Answer 1

It was started by the Babylonians, who used the sexagesimal number system (base 60). It was used because it is a relatively small number evenly divisible by a large number of numbers. (2,3,4,5,6,10,12,15,20,30: 10 of them)
Also, 6 is a rather magical number. It is a perfect number (1+2+3=1*2*3). It is a factorial result. (3!). It is the product of the first two primes.

Answer 2

Because in ancient times calendars were 360 days long so one day would have been a degree of the circle that was a year.

Now everyone knows that a year is 365.24...days long. Were those ancient people so stupid that they couldn't figure out that a year was more than 360 days long? Probably not. I'm thinking that there was a time when a year was 360 days. When did that change?

If you read the Bible, there was a time when the Earth was nearly destroyed by a flood. Not only did it rain 40 days and 40 nights, but the depths were opened up and the waters poured forth. Just like a figure skater doing a pirouette spins faster as they pull their arms towards their center of mass, so to did the Earth spin faster as the land over the great caverns fell and the lighter water came up.

The Mayan calendar was originally 360 days long but 5+ very evil days were later added. Why?

I believe that the 360 degrees of a circle is a comment that the Bible is an accurate description of our origins and early history.

Answer 3

It dates back to ancient Mesopotamia (now Iraq). Early astronomers miscounted the number of days in a year, and pegged it 360. Scales of sun position were laid out using that many points.
