The spookiest month of the year has arrived, and with it, a calendar full of offbeat holidays. Between your autumnal walks, horror movie marathons, and oh, National Cat Day on October 29 (which is basically the year’s most important holiday here at Mental Floss) see if you can squeeze in a few of these unconventional celebrations.

1. October 1: World Vegetarian Day

It’s easy enough to eat meat-free for a day, but this celebration is intended to kick off a month of vegetarian awareness and encourage more lasting change.

2. October 2: World Farm Animals Day

This may seem at odds with World Vegetarian Day, until you consider that this is actually a day to protest the farm in farm animal and the cruel conditions it implies. It’s an admirable effort, but the founders of World Farm Animals Day were a little heavy-handed in their decision to celebrate the cause on Gandhi’s birthday.

3. October 2: National Custodial Worker’s recognition Day

Because really, we should be celebrating them every day.

4. October 4: Ten-Four Day

The fourth day of the 10th month of the year is the day the world celebrates radio operators, to which we say, “Ten-Four.”

5. October 4: National Ships-In-Bottles Day

Someone spent a lot of time making this art happen, so let’s take a little time to appreciate it.

6. October 7: World Smile Day

If the calendar says you have to do it, you have to do it.

7. October 8: National Pierogi Day

On this day in 1952, pierogies were first delivered to a grocery store in Shenandoah, Pennsylvania, and we’ve been devouring them ever since.

8. October 9: Bring Your Teddy Bear to Work/School Day

No judgment here if you’ve entered the working world and have yet to outgrow your teddy bear—in fact, all the more reason to celebrate.

9. October 9: International Top Spinning Day

A good day to head to the toy store and take a spin.

10. October 10: National Handbag Day

We carry them around, but in many ways, it’s the handbags that carry us.

11.October 10: National Cake Decorating Day

Making a boxed cake recipe and applying the frosting with a butter knife definitely counts.

12. October 11: Southern Food Heritage Day

Sorry, but if you’re not eating a plate of chicken and waffles like the above, or something equally Southern, on October 11, you’re doing it wrong.

13. October 12: International Moment Of Frustration Scream Day

To celebrate this organized catharsis, go outdoors at 12 p.m. Greenwich Mean Time (8 a.m. EST) and scream for 30 seconds.

14. October 15: National Grouch Day

For those who love one, and those who are one.

15. October 15: National Face Your Fears Day

The spookiest month of the year is as good a time as any.

16. October 16: Hagfish Day

These eel-shaped, slime-producing fish are fairly disgusting (seriously), but they’re also kind of awesome. They have four hearts, have been around for hundreds of millions of years, and can feed through their skin. So while it might not be beautiful, the humble hagfish does deserve a little love and respect.

17. October 16: Dictionary Day

October 16th is Noah Webster’s birthday, so take a break from your lackadaisical use of the English language, k?

18. October 17: Get Smart About Credit Day

This American Bankers Association holiday is all about educating the public on credit—and if that stresses you out, you should probably be observing this quirky commemoration.

19. October 19: Sweetest Day

Traditionally celebrated in the Midwest and Northeastern United States, Sweetest Day is a lot like Valentine’s Day, which—depending on your outlook—is either a very good thing or a very bad thing.

20. October 19: Evaluate Your Life Day

It’s time.

21. October 22: Smart Is Cool Day

This is one that holiday that Mental Floss HQ can really get behind.

22. October 23: National Mole Day

Neither a tribute to the animal, nor a skin feature, nor an undercover spy, Mole Day honors Avogadro’s Number, which is a basic measuring unit in chemistry.

23. October 23: Canning Day

Nicolas Appert—the inventor of hermetically sealed food preservation and the “father of canning”—was born around this time circa 1750, and this day celebrates all things that come in jars. So, you know, put a lid on it.

24. October 26: National Mule Day

Now that you’ve celebrated moles, give a tip of the hat to mules—literal ones this time. On October 26, 1785, a pair of Spanish mules arrived in the U.S. as a gift from King Charles III. They’re said to have been the first mules bred in this country, by George Washington himself.

25. October 27: Cranky Co-workers Day

Not that you have any of those …

26. October 27: Mother-in-Law Day

Unfortunately, this comes after National Forgiveness Day, so if you forget to give her a call it might be a long year before she forgives you.

27. October 29: National Cat Day

We know you don’t need a date in the calendar for this, but it makes your Instagrams all that much more justified.

28. October 30: National Candy Corn Day

Feel free to debate the merits of a holiday for this highly controversial, tricolored confection.

29. October 30: Checklists Day

Put this one on your to-do list!

30. October 30: Create A Great Funeral Day

Much of October is spent focused on ghouls and goblins, but this day is all about confronting the scariest thing of all: mortality. Between your apple orchard outings and haunted house trips, make sure you and your loved ones have a plan for after you’ve shuffled off this mortal coil. Happy October?

31. October 30: Haunted Refrigerator Night

This offbeat holi-night is about exploring the darker corners and containers of your fridge. After all, we’ve all got some metaphorical skeletons lurking in there.

32. October 31: National Magic Day

Halloween, shmalloween. This holiday is fittingly held on the anniversary of the death of Harry Houdini.

33. October 31: National Knock-Knock jokes Day

There’s no better time than the spookiest day of the year to tell some good (or bad) knock-knock jokes.
