National days to celebrate this month

September Calendar

Labor Day kicks off many exciting things in September, the first month of the fall season. The month is associated with kids of all ages beginning the school year. In addition, the long-awaited football season reappears. It's also the month where the mystical harvest moon makes its appearance; it's simply the name of the fullest and brightest moon that shows up nearest the autumnal equinox, or, the beginning of fall. Sometimes, but not always, Rosh Hashanah is celebrated in September, and other times in October.

Here are the holidays and special days that occur in September and cover a large range of topics.
