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.

25 Offbeat Holidays You Can Celebrate in December

Whether you're a holiday fanatic who wants even more to celebrate, or a Scrooge with a burning desire to buck tradition, we've got plenty of offbeat observances to put on your calendar.

1. December 1: Giving Tuesday

After indulging on Thanksgiving, and shopping on Friday, Monday, and probably the whole weekend in between, Giving Tuesday—which occurs annually on the Tuesday following Thanksgiving—encourages people to engage in charitable activities.

2. December 4: National Cookie Day

ThitareeSarmkasat/iStock via Getty Images

December isn’t exactly lacking in opportunities to indulge in sweet treats, but today it’s your offbeat-holiday-given right to mix, bake, and/or eat as many cookies as you can handle.

3. December 5: Bathtub Party Day

There's a lot to be done between now and the end of the year. Take a minute to breathe, relax, and take in a soak.

4. December 5: International Ninja Day

The official website of Ninja Day alleges this holiday not only honors all things stealth and nunchucks, but also combats the more nautical offbeat holiday Talk Like a Pirate Day, which takes place in September. Creep, sneak, or redirect all of your URLs to Ninja activity—as long as you forgo the “arrrr matey’s” and eye patches for ominous silence and masks, you’re correctly celebrating this international holiday.

5. December 6: National Pawnbrokers Day

solitude72/iStock via Getty Images

If you thought good ol' St. Nicholas was the patron saint of reindeer and stockings, think again: The actual Nikolaos of Myra was the patron of things like the falsely accused and pawnbrokers, and on this day we acknowledge the latter.

6. December 9: Weary Willie Day

Professional clown Emmett Kelly created one of the more memorable clown characters of the 20th century: “Weary Willie.” Unlike many of his clown predecessors, Weary Willie opted out of white face paint and broad slapstick for the “tramp” look popular among Depression-era derelicts. One of his signature routines involved attempting to sweep up after circus acts, and failing in spite of himself—to the delight and empathy of the audience.

7. December 10: Jane Addams Day

December 10 is the day that the Nobel Prize Award Ceremonies have been held every year since 1901. Consequently, there are a lot of firsts that fall on this date, like the first American woman to be honored. That would be Jane Addams, founder of our current social work industry and prominent women's suffrage leader. On the anniversary of that award, given in 1931, we remember her life and work.

8. December 11: Official Lost And Found Day

Visit a thrift store, see if you can find that book you’ve misplaced, or invest in a memory-boosting regime so you’ll be losing things less frequently.

9. December 12: Poinsettia Day

alicjane/iStock via Getty Images

This day doesn't just celebrate the festive flower—it also marks the death of its namesake, Joel Roberts Poinsett. The botanist (and first U.S. Ambassador to Mexico) brought clippings of Euphorbia pulcherrima back to the States from southern Mexico, and grew the plant at his South Carolina home.

10. December 12: Gingerbread Decorating Day

Whether you’re a craftsman or an eater, today is the day for you.

11. December 13: National Day Of The Horse

Callipso/iStock via Getty Images

In 2004, the Senate signed legislation to officially make the second Saturday of December the National Day of the Horse. We really shouldn’t have to explain the reason horses need to be celebrated—just look at them!

12. December 13: National Cocoa Day

The weather outside is starting to get frightful, but what better cure for the temperature blues than a nice cup of hot cocoa? A down coat or a wool hat simply can’t compete in the taste department.

13. December 14: Monkey Day

Michael Warren/iStock via Getty Images

Officially, Monkey Day is an “annual celebration of all things simian, a festival of primates, a chance to scream like a monkey and throw feces at whomever you choose.” The origins of the holiday are unknown, though it has been observed since at least 2003.

14. December 15: Cat Herders Day

Technically this day is for all those who work jobs that could be described as like trying to herd cats, but it’s also probably acceptable to celebrate by trying to wrangle a cute feline.

15. December 16: Barbie And Barney Backlash Day

nicescene/iStock via Getty Images

Doesn’t seem like a coincidence that this holiday occurs in December: It’s the one day a year when you can tell your kids that Barbie and Barney don’t exist.

16. December 17: Wright Brothers Day

Made an official holiday in 1963 by Presidential Proclamation, this holiday marks the day in 1903 when Orville and Wilbur Wright achieved the first ever successful (documented) controlled airplane flight near Kitty Hawk, North Carolina.

17. December 18: Underdog Day

Observed annually on the third Friday of December since 1976, this is a reminder to honor the little guy. We’re always rooting for them, but there’s a holiday to celebrate, too.

18. December 21: Humbug Day

Michael Burrell/iStock via Getty Images

Get out all your bahs and scowls and growls now: no one will tolerate them come Christmas.

19. December 21: Phileas Fogg Win A Wager Day

In Jules Verne's 1873 classic novel Around the World in 80 Days, Phileas Fogg bets that he can travel the entire globe, between 8:45 p.m. on October 2, and 8:45 p.m. on December 21. Keep an eye out for him on this day.

20. December 22: Forefathers’ Day

On December 21, 1620 (it was a Monday) the Pilgrims aboard the Mayflower landed in Plymouth, Massachusetts, and since that basically kick-started our country's history since then, we celebrate it.

21. December 23: Festivus!

SafakOguz/iStock via Getty Images

For those who shy away from the more traditional December holidays, there’s always Festivus for the rest of us. Created by a Seinfeld writer's father and popularized by Frank Costanza, this secular holiday that involves gathering around an aluminum pole and airing your grievances has continued to gain a following since its introduction in 1997. If you haven’t seen the episode, there’s an entire website that spells out how to celebrate Festivus from start to finish. (Test your Festivus knowledge with this quiz.)

22. December 25: A’phabet Day

A pun on noel, this offbeat ce'ebration is designed to high'ight the arbitrary nature of many of the year's si''ier ho'idays. Whi'e you're unwrapping presents and eating your Christmas feast, 'eave a'' the Ls out of written and spoken communication for a festive activity that wi'' sure'y infuriate your 'oved ones.

23. December 26: National Whiners Day

Get it all out, whiners. Today is your day.

24. December 29: Tick Tock Day

In case you needed another reminder of the inevitable passage of time and/or an occasion to reevaluate how those 2019 resolutions are going!

25. December 31: Make Up Your Mind Day

Tomorrow’s a new year! Time to fight that indecisiveness and make a decision—maybe even a resolution, if you will.
