September is the ninth month of the year in both the Julian calendar, Julian and Gregorian calendars, the third of four months to have a length of 30 days, and the fourth of five months to have a length of fewer than 31 days. September in the Northern Hemisphere and March in the Southern Hemisphere are seasonally equivalent.

In the Northern hemisphere, the beginning of the meteorological autumn is on 1 September. In the Southern hemisphere, the beginning of the meteorological Spring (season), spring is on 1 September.　

September marks the beginning of the Eastern Orthodox liturgical calendar, ecclesiastical year in the Eastern Orthodox Church. It is the start of the academic term, academic year in many countries of the northern hemisphere, in which children go back to school after the Summer vacation, summer break, sometimes on September 1, the first day of the month.

September (Roman month), September (from Latin ''septem'', "seven") was originally the seventh of ten months in the oldest known Roman calendar, the Roman calendar#Legendary 10-month calendar, calendar of Romulus , with March (Latin ''Martius (month), Martius'') the first month of the year until perhaps as late as 451 BC. After the calendar reform that added Ianuarius, January and Februarius, February to the beginning of the year, September became the ninth month but retained its name. It had 29 days until the Julian reform, which added a day.

September events

Ancient Roman observances for September include Ludi Romani, originally celebrated from September 12 to September 14, later extended to September 5 to September 19. In the 1st century BC, an extra day was added in honor of the deified Julius Caesar on 4 September. Epulum Jovis was held on September 13. Ludi Triumphales was held from September 18–22. The Septimontium was celebrated in September, and on December 11 on later calendars. These dates do not correspond to the modern Gregorian calendar.

September was called "harvest month" in Charlemagne's calendar. September corresponds partly to the Fructidor and partly to the Vendémiaire of the First French Republic, first French republic. September is called ''Herbstmonat'', harvest month, in Switzerland. The Anglo-Saxons called the month ''Gerstmonath'', barley month, that crop being then usually harvested.

In 1752, the British Empire adopted the Gregorian calendar. In the British Empire that year, September 2 was immediately followed by September 14.

On Usenet, it is said that September 1993 (Eternal September) never ended.
