Design by the Babylonians. They understood that the perimeter of a hexagon is 6 times the radius of the circle that contains it. And since they had a base 60 numerical system, they subdivided the six wedge shapes within the circle by 60, therefore 6x60=360. They then divided the day into 4 segments of 6 - basically sunrise until noon, noon until sunset, and the portions of night corresponding to that. Again, using base 60, these were further subdivided into minutes and seconds.
