360 Days in Year - 365 Days in Year
 
In the eighth century B.C.E., civilizations all over the world either discarded or modified their old 360 day calendars. The 360 day calendars had been in use for the greater part of a millennium. In many places, month lengths immediately after that change were not fixed, but were based instead upon observation of the sky.
