#5. Father of leap year
The Romans used a calendar system based on the lunar cycle which only had 355 days in a year and they were expected to add up the additional days as per seasons. But it was not always the case. When Caesar came to power, he implemented a new system which was in sync with the solar cycle and had 365 days in a year. But since a solar year has 365 1/4 days, an extra day was added every four years to make up the difference.
