The Gregorian Calendar is an almost identical improvement on the Julian Calendar. The names of the months and the number of days per month are the same. The only difference is that the Gregorian Calendar has three fewer leap year days out of every 400 years. The Julian Calendar averages 365.25 days per year, and the Gregorian Calendar averages 365.2425 days per year.

He knew that it was impossible to say when Jesus was born, but he knew, or thought he knew, when Herod died. So, he chose to begin his Christian calendar on the year of Herod's death, and he based this on the reign of the Roman emperor Augustus. Unaware that Augustus only adopted that name four years after his reign began, going by his birth name of Octavius until then, Exiguus commenced his calendar just 4 years too late.
