Julius Caesar was behind the origin of leap year in 45 BC. The early Romans had a 355 day calendar and to keep festivals occurring around the same season each year a 22 or 23 day month was created every second year. Julius Caesar decided to simplify things and added days to different months of the year to create the 365 day calendar, the actual calculation were made by Caesar's astronomer, Sosigenes. Every fourth year following the 28th day of Februarius (February 29th) one day was to be added, making every fourth year a leap year.
In 1582, Pope Gregory XIII further refined the calendar with the rule that leap day would occur
The concept of leap years was first proposed by Julius Caesar in 46 BC and later refined by Pope Gregory XIII in 1582 to account for the discrepancy between the calendar year and the solar year. This adjustment helps keep the calendar year aligned with the Earth's orbit around the Sun.
