September Month

September in the Northern Hemisphere is the seasonal equivalent of March in the Southern 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]
September begins on the same day of the week as December every year, because there are 91 days separating September and De

cember, which is a multiple of seven (the number of days in the week). No other month ends on the same day of the week as September in any year.
In Latin, septem means "seven" and septimus means "seventh"; September was in fact the seventh month of the Roman calendar until 46 BC, when the first month changed from Kalendas Martius (1 March) to Kalendas Januarius (1 January). It is the sixth month of the Astrological calendar, which begins end of March/Mars/Aries.
