What Is a Leap Year?
3. Julian Calendar
We can thank Ancient Rome for a lot of the traditions and customs that we have today. Even widely celebrated occasions such as Christmas Day are credited to the ancient empire that was based in what is now Italy. They can also be credited for being the first to add a leap year to our calendars.
The Julian calendar was developed by one of Ancient Rome’s most famous emperors, Julius Caesar. The calendar was almost identical to the one we have today, with 365 days and another day added every 4 years. In this case, the calendar repeated February 23 every four years.
