September

September is the ninth month of the year in the Julian and Gregorian calendar. It was originally the seventh month of the Roman calendar until 153 BCE.

Naming September - The Seventh Month

September is the ninth month of the year in the Julian and Gregorian calendars and has a length of 30 days.  The month kept its original name from the Roman calendar in which septem means “seven” in Latin marking it as the seventh month.

September was named during a time when the calendar year began with March, which is why its name no longer corresponds with its placement in the Julian and Gregorian calendars.

History of September

September was the seventh month that had a length of 30 days in the Roman calendar. It became the ninth month with a length of 29 days when King Numa Pompilius reformed the calendar and added the months of January and February around 700 BCE. Julius Caesar added one day to the month making it 30 days long during the Julian calendar reform.
