September (pronunciation) is the ninth month of the year in the Gregorian Calendar and one of four Gregorian months with 30 days.

September in the Southern Hemisphere is the seasonal equivalent of March in the Northern Hemisphere.

In the Northern hemisphere, the beginning of the meteorological autumn is 1 September. In the Southern hemisphere, the beginning of the meteorological spring is 1 September.[1]

In Latin, septem means "seven" and septimus means "seventh"; September was in fact the seventh month of the Roman calendar until 153 BC, when the first month changed from Kalendas Martius (1 March) to Kalendas Januarius (1 January).[2]

September marks the beginning of the ecclesiastical year in the Eastern Orthodox Church.

September begins on the same day of the week as December every year, because there are 91 days separating September and December, which is a multiple of seven (the number of days in the week).
