Even after Labor Day has come and gone, there is still plenty to celebrate in September, as the list of holidays below proves. And if nothing in here catches your fancy, just remember that September is also Happy Cat Month.

1. September 3: National Skyscraper Day

Celebrate the architectural triumphs that make the skyline of your city unique by paying tribute to oversized buildings. This day coincides with the birthday of Louis Sullivan, the influential architect who helped develop and advance the skyscraper movement in the late 19th century.

2. September 4: Bring Your Manners To Work Day

Whatever it is you do, do it politely. (Even if it’s via Zoom this year.)

3. September 4: Eat an Extra Dessert Day

You may have observed this holiday a little early on Labor Day, but go ahead and indulge those residual gluttonous impulses because this holiday gives you the green light. That leftover pie isn’t going to eat itself, so really, it’s the least you can do.

4. September 4: Newspaper Carrier Day

This day honors Barney Flaherty, who was hired as the first paperboy for the New York Sun way back in 1833. (International Newspaper Carrier Day, meanwhile, is happening on October 10.)

5. September 5: Cheese Pizza Day

No frills, just deliciousness.

6. September 5: Be Late For Something Day

While a lot of people don't need an excuse to be late, here’s a day for all you punctual types out there to cut loose and be tardy for once.

7. September 6: National Fight Procrastination Day

One of these years we're going to get around to celebrating.

8. September 7: Neither Rain Nor Snow Day

September 7 is the anniversary of the opening of the New York Post Office in 1914, and the name of the holiday comes from the inscription on the building: "Neither snow nor rain nor heat nor gloom of night stays these couriers from the swift completion of their appointed rounds."

9. September 10: TV Dinner Day

The TV dinner was first introduced to consumers in the United States by C.A. Swanson & Sons in the early 1950s. This pre-packaged, frozen meal would not only provide you a whole dinner with the slight flick of an oven—it was also designed for ease of consumption while parked in front of a television screen.

10. September 10: Swap Ideas Day

This is less of a celebration and more of a reminder to not hoard good ideas: They're much more useful when you put them out into the open.

11. September 13: Kids Take Over The Kitchen Day

Just maybe don't be so quick to eat what they make (or keep a close eye on how they’re preparing it).

12. September 13: Grandparents Day

Mom and dad get one, so why not the older generation? Grandparents Day has been celebrated annually on the first Sunday after Labor Day since 1978. Many other countries have their own versions of this day at some point during the year and, unlike the U.S., they often give grandmothers and grandfathers their own separate days. Just something to think about.

13. September 13: National Hug Your Hound Day

If you don't have a hound of your own to hug, looking at photos of other people hugging their hounds is a perfectly acceptable substitute.

14. September 16: World Play-Doh Day

Today's the perfect day to do something with your favorite childhood clay! It's OK with us if you mostly just smell it.

15. September 16: Mayflower Day

This is the anniversary of the day in 1620 when 102 men, women, and children set sail from Plymouth, England, aboard the Mayflower.

16. September 16: Anne Bradstreet Day

September 16 was officially proclaimed a holiday by the governor of Massachusetts to honor Anne Bradstreet, an underappreciated figure in the history of American literature. Bradstreet, who emigrated to the colonies along with her family in 1630, is considered to be America's first poet for her 1650 work, The Tenth Muse Lately Sprung Up in America, published, supposedly, without her knowledge.

17. September 17: Constitution Day

On September 17, 1787, the Constitution of the United States of America was officially signed—although it wasn't voted into effect until two years later. Since 1952, Citizenship Day has also been celebrated on September 17.

18. September 19: International Talk Like a Pirate Day

International Talk Like a Pirate Day just might be the most widely-known offbeat holiday, because who doesn't relish the chance to call everyone matey?

19. September 21: World Gratitude Day

In 1977, those hippies at the United Nations Meditation Group established World Gratitude Day to appreciate existence. Even the least existential among us can recognize a thing or two in our lives for which we feel grateful. For example, we here at Mental Floss are grateful that you’re still reading this article.

20. September 22: Elephant Appreciation Day

This ode to oversized pachyderms was created by Mission Media Inc. founder Wayne Hepburn in 1996. Years before, his daughter had given him an elephant paperweight that led to a lifelong obsession with the animals, which eventually culminated in the creation of this holiday.

21. September 22: American Business Women's Day

First recognized by Congressional resolution in 1983, this honoring of the female half of the workforce is celebrated annually on the anniversary of the 1949 founding date of the American Business Women's Association.

22. September 22: Hobbit Day

On the birthday of both Frodo and Bilbo Baggins, J.R.R. Tolkien fans celebrate all things The Lord of the Rings. It is also the day that determines the larger celebration of Tolkien Week.

23. September 22: Dear Diary Day

Get reacquainted with your diary … and penmanship … and maybe some feelings.

24. September 22: National Centenarian’s Day

We realize that the people above probably aren't centenarians, but we bet they'll be just as fun and active when they are.

25. September 24: National Punctuation Day

Let the Oxford comma debates begin!

26. September 25: National One-Hit Wonder Day

Get your playlist started now.

27. September 26: Johnny Appleseed Day

There is some debate about whether this American folklore hero should be celebrated on the anniversary of his birth on September 26, or on the anniversary of his death in March. But this is a celebration, after all, so let's stick with his birthday.

28. September 28th: Drink Beer Day

Finally, an excuse.

29. September 29: International Coffee Day

We won't talk to you before you've celebrated this one.

30. September 29: Biscotti Day

Surely it's no coincidence that this falls on the same day as International Coffee Day, and that's why we love the offbeat holiday gods.

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.

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

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.

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

ChristianChan/iStock via Getty Images

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

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

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
