2024 Holidays and Observances in September (2024)

Labor Day kicks off many exciting holidays in September, including the unofficial start of the fall season. September includes federal holidays, religious holidays, and other celebrations and observances, such as the beginning of the school year and football season, the emergence of the harvest moon, and so much more.

September plays host to daily, weekly, and monthly celebrations and observances. Besides Labor Day and Patriot Day honoring 9/11, the International Day of Peace comes later in the month. Some fun, quirky, or lesser-known holidays are International Talk Like a Pirate Day, National Cheese Pizza Day, and National Comic Book Day.

If you're looking for a reason to celebrate or be mindful, here are the holidays and observances in September 2024.

Major Holidays and Observances in September 2024

The only federal holiday in September 2024 is Labor Day on Monday, September 2. While not a federal holiday, Patriot Day (9/11 Remembrance) is considered a crucial day of observance. On this day, the United States holds memorials and remembrance ceremonies to honor the fallen and first responders from the September 11, 2001 tragedy. On September 15 and 16, Muslims worldwide celebrate Mawlid, the birthday of the Islamic Prophet Muhammad. September 15 also kicks off National Hispanic Heritage Month.

Another noteworthy date is the autumnal equinox, on September 22, when the sun is exactly above the equator and day and night are of equal length.
