Its source is an English expression meaning "The ninth month of the year."
The name September ranked 4110th in popularity for females of all ages in a sample of the 1990 US Census.
Though this name appears on the 1990 U.S. Census lists, it is used by only a small percentage of the general population.
Though it is the ninth month on the modern western calendar, September literally means ''seventh month.'' This is because the calendar year of the ancient Romans began on the first of March, rather than the first of January.
