Who found the calendar?

Answer 1

The calendar that we use today is called the Gregorian calendar, created by Pope Gregory XIII. Before that, there was the Roman calendar, which was a lunar calendar, comprising 10 months and an intercalated month. Next came the Julian calendar, a twelve-month solar calendar introduced by Julius Caesar in 46 bc, consisting of 365 days, with an extra day every four years.
