Etymology

The word "September" originates from the Latin septem, meaning "seven," as it was the seventh month in the ancient Roman calendar (which began with March). The suffix -ember (from Latin -mēnsis, meaning "month") was added to denote its place in the calendar. Despite calendar reforms shifting it to the ninth position, the name retained its original numerical root.
