From Wikipedia, the free encyclopedia.
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").
