The month of July is a derivation of the name, “Julius Caesar”. The ancient Romans opted to rename “Quintilis”, the original name for July which means “fifth month” in Latin, to “July” after Caesars death because this was the same month that he was born. The Julian calendar, a western calendar used until 1582 when the Gregorian calendar supplanted it, is also attributed to Caesar as the Roman year had only 355 days and required an extra month be added, every 3 years. The ancient Romans repeatedly made the same calculation errors and continually found seasons out of synchronization with the actual calendar date observed. With the help of a few Roman scientists, Caesar removed the pre-Etruscan 10 month solar calendar in favor of the 365 day year calendar named after himself. The Roman calendar started on March 25, but was moved to January 1 with the advent of the Gregorian calendar
