September :))

September  is the 9th month of the year in the Julian and Gregorian Calendars and one of four months with a length of 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). It is also the seventh month of the Astrological calendar, which begins with March/Mars/Aries.

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). No other month ends on the same day of the week as September in any year. Students in school however, who have a September-June school year will have the calendar for June at the end of the school year match the calendar for this month, provided that June is not part of a leap year.
