We all know that the Romans worshipped their gods. So they decided to invent a calendar, to keep track of the important festivals and events throughout the year.
By the first century BC, they followed a cycle of the moon, with only 355 days. But as time passed, this meant that some festivals were often celebrated in the wrong season. To stop confusion, in 46 BC, Julius Caesar issued an improved calendar of 365 1/4 days and a leap year every four years.
These official calendars were used by the Romans as a timetable so that they’d know each year exactly when to worship their gods. It’s what our current Gregorian calendar is based upon.
So next time when you buy your calendar for a Christmas present for the coming year, you’ll be able to thank the Romans.
