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

September begins in western astrology with the sun in the sign of Virgo and ends in the sign of Libra. Astronomically speaking, the sun actually begins in the constellation of Leo and ends in the constellation of Virgo.
In Latin, septem means "seven" and septimus means "seventh"; September was in fact the seventh month of the Roman calendar until 153 BC.
