September is the ninth month of the year in the Julian and Gregorian calendars. Its length is 30 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 is on 1 September.
September marks the beginning of the ecclesiastical year in the Eastern Orthodox Church. It is the start of the academic year in many countries of the northern hemisphere, in which children go back to school after the summer break, sometimes on the first day of the month. Some Libras and Virgos are born in September, with Virgos being born on September 1st through September 22nd and Libras September 23rd through September 30.
September (from Latin septem, "seven") was originally the seventh month in the oldest known Roman calendar, the calendar of Romulus , with March being (Latin Martius) the first month of the year until perhaps as late as 451 BC. After the calendar reform that added January and 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.
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 18âÂÂ22. 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 the "harvest month" in Charlemagne's calendar. September corresponds partly to the Fructidor and partly to the Vendémiaire of the 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.
