What Month is September?
September is the ninth month of the year
September, abbreviated as Sep, is the 9th month of the Gregorian calendar, coming after August and before October.
September gets its name from the Latin word septem, meaning "seven." In the earliest Roman calendar, September was the seventh month of the year, since the year originally began in March.
Even after January and February were added to the beginning of the calendar, shifting September to the ninth month, its name remained unchanged. This explains why September's name reflects the number seven rather than its current position in the calendar.
