It’s October and Halloween is almost here. It’s the season of flickering candles, cozy blankets, and playful spookiness—the perfect backdrop for a celebration of all things mysterious, funny, and just a bit eerie.

As someone who spends countless hours digging through thousands of national days and creates national days calendars (and loves every minute of it), I couldn’t resist putting together a list of spooky holidays that captures that thrilling Halloween spirit in October. There’s a day for horror movies, a day for the notorious Chucky, a day for visiting cemeteries and much more.

Some of the national days on this list take place on October 31 just like Halloween, but a majority of them take place earlier in the month. From black cats and haunted fridges to horror movies and psychic powers, these observances will make this Halloween season unforgettable.


From Harry Potter Book Day to National Black Cat Day, October is full of magical, mischievous, and slightly eerie observances that keep the Halloween spirit alive all month long. 🎃🖤
