Where doesSeptember come from?

The first records of the word September come from before 1050. It ultimately comes from the Latin September, meaning “seventh month.”

In the 10-month Roman calendar, which started with March, September was the seventh month. When Julius Caesar took control of Rome, he changed the length of some months and added new ones because January was falling in autumn due to the calendar’s inaccuracies. He added Quintilis, later to become July (named after Julius), and Sextilis, which would later become August (named after Augustus Caesar). This is how September went from being the seventh month to the ninth. Our Gregorian calendar is based on this Julius calendar.
