October brings all the cozy, spooky and just plain fun vibes you can handle. From pumpkin spice everything to costumes galore, this month is packed with loads of reasons to celebrate and way more October holidays than you might know.
Sure, Halloween steals the spotlight with trick-or-treating, jack-o’-lanterns and literal buckets of candy. But there’s also Mean Girls Day, where we wear pink and quote lines from the movie (“That’s so fetch!”), and National Dessert Day, one of the best excuses to indulge in sugary goodness. (Yeah, we’re not sure we really need more sugar this month, but hey, we’ll never say no to dessert!) And that’s just the start of this month’s observances, which range from fun to meaningful.
Keep reading to discover the full lineup of October holidays you won’t want to miss.
