Naming September

September is the ninth month of the year in the modern-day Gregorian calendar and its predecessor, the Julian calendar. The month kept its original name from the Roman calendar where it was the seventh month. Septem means “seven” in Latin.

The month of September was named during a time when the calendar year began with March, which is why the name does not correspond with the placement in the Julian and Gregorian calendars.

  • Middle English - septembre
  • Latin name - september mensis - seventh month
