September

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.

September (from Latin septem, "seven") was originally the seventh month in the oldest known Roman calendar, the calendar of Romulus c. 750 BC, with March being (Latin Martius) the first month of the year until perhaps as late as 451 BC.

[2] After the calendar reform that added January and February to the beginning of the year, September became the ninth month but retained its name.

In the 1st century BC, an extra day was added in honor of the deified Julius Caesar on 4 September.

In the United States, September is one of the most common birth months (third most popular after August and July, which both have 31 days), as all but one Top 10 most common birthdays are in September, based on the National Center for Health Statistics statistics on births between 1994 and 2014.

September is mostly in the sixth month of the astrological calendar (and the first part of the seventh), which begins at the end of March/Mars/Aries.
