September officially marks the start of fall (and there's a holiday for it!), and we are here to celebrate every day. Better yet, every day brings its own set of festivities, so here we give you a thorough list of September Holidays and Observances for 2023 sourced from National Today's exhaustive list.

As the leaves start to turn golden hues and the temperatures start to drop, you can also celebrate everything from chess to little black dresses to beards to samosas in this set of national holidays in the USA. And don't worry if you miss any; there's always 2024 to catch them mixed in with your favorite fall activities like porch decorating and outdoor family movie nights. Before you know it, all 30 days of September will give way to all things pumpkin (including tasty pumpkin recipes!) coming out full force in October, so be sure to relish them and end at least some of them with a seasonal cocktail too. This month is sure a pleasant reprieve after all the hot temperatures of June, July, and August.

And now for those September holidays and observances! Scroll through them all and make a short list of ones you and your family can recognize to make any ordinary September day extraordinary.
