According to “Ripley’s Believe it or not“, a graveyard inscription had February 30th.
Julius Caesar’s followers took a day from February to make July (named in his honor) have 31 days instead of 30.
Augustus Caesar’s followers took a day from February to make August (named in his honor) to have 31 days instead of 30.
February became the shortest month of the calendar year with 28 days. It was given back an extra day on a leap year.
The earth takes about 365.2422 days to revolve round the sun, so the discrepancy between a solar year and the calendar year became 0.9688 day every four years (or 97 days in 4 centuries). The first correction was to designate a year divisible by 4 as a Leap Year.
In Gregorian calendar, a leap year is defined as a non-century year that is divisible by 4, and a century year that is divisible by 400. This is more accurate than the first correction.
