Background & History
September originates from the Latin word *septem*, meaning "seven," reflecting its original position as the seventh month in the Roman calendar before January and February were added (as *Janvarius* and *Februarius*) to align with the lunar cycle. Historically, it was considered late summer in the Northern Hemisphere until the Gregorian reform introduced a 12-month year. The month retains its seasonal equivalence with March in the Southern Hemisphere.
