From Star Wars Day to National Tap Dance Day, the month of May is full of delightful, offbeat holidays you should be celebrating.

May 1: Lei Day

You've heard of May Day, but this is the Hawaiian equivalent. Celebrate the islands' culture with lei-making contests, Hawaiian food and music, and even the crowning of the Lei Queen.

May 1: Mother Goose Day

Founded in 1987 by Gloria T. Delamar in conjunction with the publication of her book, Mother Goose: From Nursery to Literature, this is a day to "re-appreciate" the old nursery rhymes.

May 1: New Homeowners Day

One could argue that getting out of the rental game is a celebration in itself, but here's a holiday for brand-new homeowners anyway. (A Risky Business-style dance party would be one good way to party with all that room.)

May 2: Free Comic Book Day

Ever since 2002, the first Saturday of May has seen participating independent comic book stores across the country hand out their wares for free. Over 3 million comic books are given away each year.

May 3: National Two Different Colored Shoes Day

For people who want to practice a safe level of nonconformity.

May 4: Star Wars Day

May the fourth be with you!

May 4: International Respect For Chickens Day

You might appreciate them for the sustenance they provide, or you might appreciate them so much that you don’t use them for sustenance. Either way, celebrate the chicken today.

May 6: No Homework Day

We assume this applies to kids and adults alike.

May 7: National Cosmopolitan Day

We love a holiday with a built-in way to celebrate: in this case, with Carrie Bradshaw's favorite cocktail.

May 8: No Socks Day

The pitch for this holiday cites the lighter load of laundry foregoing socks will create. This seems specious at best—how big are your socks?— but let's all hope it will be sandal weather by this point, in which case you can and should definitely go without socks.

May 9: National Babysitter’s Day

Because, let's be real: their job isn't always easy.

May 9: National Train Day

National Train Day celebrates when the "golden spike" was driven into the final tie in Promontory Summit, Utah, to connect the Central Pacific and Union Continental railroads, creating a country unified by 1776 miles of train track.

May 10: Stay Up All Night Night

Staying up all night pretty much always leads to some great stories.

May 11: Eat What You Want Day

The best holidays encourage you to break some dietary rules and this one might be the best of all because it encourages you to break all of them.

May 12: National Limerick Day

Observed annually on the birthday of English author Edward Lear, whose 1846 A Book of Nonsense helped bring the lyrical form to popularity.

May 13: InterNational Hummus Day

Give us all the food holidays.

May 14: National Underground America Day

Underground America Day honors those who make their homes not just on Earth, but in it. It was invented by architect Malcolm Wells in 1974 and those who wish to celebrate can do so by doing things like riding the subway, burying treasure, eating root vegetables, or thinking about moles.

May 15: National Bike To Work Day

We can't promise you won't arrive to the office slightly sweaty, but we can give you permission to skip the gym after completing your cycling commute.

May 15: National Pizza Party Day

Add an extra topping to your pie: It's Pizza Party Night.AlexeyBorodin/iStock via Getty Images

Party is a relative term, by the way. You and a pizza is definitely a party.

May 16: Biographer's Day

This is celebrated annually on the anniversary of the 1763 meeting in London between James Boswell and Samuel Johnson, which launched one of the most famous author-subject relationships and produced the biographies Journal of a Tour to the Hebrides and Life of Samuel Johnson.

May 16: Mimosa Day

What would brunch be without them?

May 18: International Museum Day

On this day, the entire planet celebrates museums and all the amazing things they have to offer—many of them via virtual tours.

May 20: Eliza Doolittle Day

Today is a good day to channel your inner Eliza (either before or after the etiquette lessons—the choice is yours).

May 22: National Maritime Day

A Presidential Proclamation issued in 1933 made this day an official holiday dedicated to recognizing the maritime industry. It is set to coincide with the date in 1819 that the American steamship Savannah set sail on the first ever transoceanic voyage under steam power.

May 22: World Goth Day

They may act like they don't want/need/care about having a day in the calendar, but come on, everyone wants to be celebrated.

May 23: World Turtle Day

Celebrate by reading 20 things you didn't know about sea turtles right here.

May 24: International Tiara Day

Who's a pretty princess? Anyone who wants to celebrate Tiara Day. May 24th was chosen as the date to celeberate this piece of headgear because it also happens to be the birthday of Queen Victoria.

May 25: National Tap Dance Day

The perfect day to put on your dancing shoes.

May 25: Towel Day

To honor celebrated author Douglas Adams, fans carry around a towel all day. The tradition is a nod to a passage in The Hitchhiker's Guide to the Galaxy about the importance of towels: "A towel, [The Hitchhiker's Guide to the Galaxy] says, is about the most massively useful thing an interstellar hitchhiker can have." Good enough for us.

May 30: Loomis Day

This is a day to honor Mahlon Loomis, an oft-forgotten Washington D.C.-based dentist who received the first U.S. patent on a wireless telegraphy system in 1872—before Guglimo Marconi, who is credited with inventing the first radio, was even born.

10 of the Best Indoor and Outdoor Heaters on Amazon

With the colder months just around the corner, you might want to start thinking about investing in an indoor or outdoor heater. Indoor heaters not only provide a boost of heat for drafty spaces, but they can also be a money-saver, allowing you to actively control the heat based on the rooms you’re using. Outdoor heaters, meanwhile, can help you take advantage of cold-weather activities like camping or tailgating without having to call it quits because your extremities have gone numb. Check out this list of some of Amazon’s highest-rated indoor and outdoor heaters so you can spend less time shivering this winter and more time enjoying what the season has to offer.

Indoor Heaters

1. Lasko Ceramic Portable Heater; $20

Lasko/Amazon

This 1500-watt heater from Lasko may only be nine inches tall, but it can heat up to 300 square feet of space. With 11 temperature settings and three quiet settings—for high heat, low heat, and fan only—it’s a dynamic powerhouse that’ll keep you toasty all season long.

Buy it: Amazon

2. Alrocket Oscillating Space Heater; $25

Alrocket/Amazon

Alrocket’s oscillating space heater is an excellent addition to any desk or nightstand. Using energy-saving ceramic technology, this heater is made of fire-resistant material, and its special “tip-over” safety feature forces it to turn off if it falls over (making it a reliable choice for homes with kids or pets). It’s extremely quiet, too—at only 45 dB, it’s just a touch louder than a whisper. According to one reviewer, this an ideal option for a “very quiet but powerful” heater.

Buy it: Amazon

3. De’Longhi Oil-Filled Radiator Space Heather; $79

De’Longhi/Amazon

If you prefer a space heater with a more old-fashioned vibe, this radiator heater from De’Longhi gives you 2020 technology with a vintage feel. De’Longhi’s heater automatically turns itself on when the temperatures drops below 44°F, and it will also automatically turn itself off if it starts to overheat. Another smart safety feature? The oil system is permanently sealed, so you won’t have to worry about accidental spills.

Buy it: Amazon

4. Aikoper Ceramic Tower Heater; $70

Aikoper/Amazon

Whether your room needs a little extra warmth or its own heat source, Aikoper’s incredibly precise space heater has got you covered. With a range of 40-95°F, it adjusts by one-degree intervals, giving you the specific level of heat you want. It also has an option for running on an eight-hour timer, ensuring that it will only run when you need it.

5. Isiler Space Heater; $37

Isiler/Amazon

For a space heater that adds a fun pop of color to any room, check out this yellow unit from Isiler. Made from fire-resistant ceramic, Isiler’s heater can start warming up a space within seconds. It’s positioned on a triangular stand that creates an optimal angle for hot air to start circulating, rendering it so effective that, as one reviewer put it, “This heater needs to say ‘mighty’ in its description.”

Buy it: Amazon

Outdoor Heaters

6. Mr. Heater Portable Buddy; $104

Mr. Heater/Amazon

Make outdoor activities like camping and grilling last longer with Mr. Heater’s indoor/outdoor portable heater.

Simply open the heater’s bottom door to insert a propane tank, power it on, and sit back to let it warm up your backyard. The bright, contained flame from the propane doubles as an outdoor light.

Buy it: Amazon

8. Solo Stove Bonfire Pit; $345

Solo Stove/Amazon

This one is a slight cheat since it’s a bonfire pit and not a traditional outdoor heater, but the Solo Stove has a 4.7-star rating on Amazon for a reason. Everything about this portable fire pit is meticulously crafted to maximize airflow while it's lit, from its double-wall construction to its bottom air vents. These features all work together to help the logs burn more completely while emitting far less smoke than other pits.

October—the spookiest month of the year—is upon, 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

RubyMirriam/iStock via Getty Images

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.

3. October 2: National Custodian Day

Because really, we should be celebrating them every day.

4. October 2: World Smile Day

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

5. 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.”

6. 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.

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 10: National Handbag Day

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

9. October 10: National Cake Decorating Day

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

10. October 11: Southern Food Heritage Day

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

11. October 14: International Top Spinning Day

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

12. October 15: National Grouch Day

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

13. October 15: 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.

14. October 16: Dictionary Day

perkmeup/iStock via Getty Images

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

15. October 17: 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.

16. October 19: Evaluate Your Life Day

It’s time.

17. October 21: Hagfish Day

ffennema/iStock via Getty Images

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.

18. October 22: Smart Is Cool Day

kamianskoi/iStock via Getty Images

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

19. 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.

20. October 23: Canning Day

Mizina/iStock via Getty Images

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.

21. October 25: 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.

22. 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.

23. October 27: Cranky Co-workers Day

Not that you have any of those ...

24. October 29: National Cat Day

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

25. October 30: National Candy Corn Day

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

26. October 30: Checklists Day

Put this one on your to-do list!

27. October 30: Create A Great Funeral Day

RobertHoetink/iStock via Getty Images

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?

28. October 30: Haunted Refrigerator Night

Songbird839/iStock via Getty Images

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.

29. October 31: National Magic Day

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