Friday Factoid: Did Caesar “Invent” Leap Day?

The Roman dictator Julius Caesar is credited as being the first leader to adopt the current leap year system. The ancient Roman calendar system was based on 355 days per year with a “catch up” month every few years. Caesar decided in 46 B.C. to revise the calendar system to be based on 365 days per year plus an additional day every four years, in order to align the differences between the lunar and solar calendars.
