All the September Holidays and Observances to Kick Off Fall

Summer may be winding down, but September is just getting started! The month ushers in the first day of fall, bringing with it crisp air, vibrant foliage, and, of course, pumpkin-spiced everything. But beyond indulging in seasonal snacks, it’s the perfect time to cozy up and watch fall movies, carve pumpkins, and dive into all the other fall traditions that make autumn so special.

And aside from your typical fall fare and fun, the month of September also boasts a variety of holidays! While there are well-known observances like Labor Day and Patriot Day, there are many lesser-known celebrations to discover, too. Love chocolate milkshakes? There’s a holiday for that! Can't get enough waffles at breakfast? September has a whole week dedicated to them. And if you're a proponent of the power of a black dress, don’t miss National Little Black Dress Day.

There are also some seasonally centric days to enjoy, such as National Scarf Day and National Hot Mulled Cider Day. The list goes on, but you get the idea. So, grab your calendar and get ready to mark down these fun September holidays and observances for 2025!
