September is the ninth month of the year in the Gregorian Calendar, with 30 days. The name comes from the Latin septem, for "seven" -- September was originally the seventh month of the year, before January and February were inserted.
September begins on the same day of the week as December every year.
In Greek civilization, September was called Boedromion.
In the Irish Calendar the month is called Meán Fómhair (literally "Middle Autumn").
