"Every day is a holiday for Spongebob even if he has to make one up."Are you bored with the usual holidays? How about celebrating a new holiday! This trope deals with holidays non-existent in the real world, in other words holidays that only exist in a story's universe. Just about any fictional fantasy setting with their own fantasy nations/history/cultures will come with their own fictional holidays. See also You Mean "Xmas", Alternative Calendar.

Anime & Manga
- Tenchi Muyo! has the Juraian holiday Startica, which happens to involve Christmas trees for some reason.note
- "Heaven's Day" in The Big O, which was the day Paradigm City was founded. It's clearly related to Christmas (giving presents, trees, etc.) Alex Rosewater seems to know the significance of its trappings, and mentions it's "the day God's son was born" - which has some ominous overtones given his ambitions...
- Jewelpet Twinkle has the Snow Night, which is just Jewel Land's equivalent of Christmas.
- Jewelpet Sunshine: episode 7 is about the Thanks to Jewel Day, by all apearances a day where humans have to thank the animals for letting them be in Jewel Land by being totally subservient to them. In the day after that, the opposite happens.
- Lady Jewelpet has the Thanks Jewel Palace Day, celebrated in episode 28 with a carnival.
- An issue of the ALF comic book revealed that Melmac had a variety of holidays.
- Shown inside are:
- Eat Off The Floor Day, in which celebrants (are supposed to) dress in bathing suits and eat "duck delight" while sitting on the floor, celebrating the discovery of linoleum by Alexander Graham Cracker. The foodstuff is not made of duck, but makes those who eat it think they're ducks. The two adult Tanners sample it early and go quackers.
- Wear A Plant Day, in which a tree is planted that is supposed to grow to about a meter in height by evening. It gets nixed immediately by Willie, who discards the seed. A chance raccoon, however, knocks over the can, planting the seed... which begins to grow at an astonishing rate, due to Earth's relatively rich soil. Within the hour, it threatens to start a forest in the backyard that will spread from there in California to the Mississippi River by Thursday.
- Shown on the front cover and mentioned within are: Bathe With A Policeman Day, Goomer's Birthday, UPC Symbol Day, Eat Your Calendar Day (which appears to be when cover was made, judging by Gordon's activities), Sit On A Friend Day, Play With Your Spaghetti Day, Give A Present To A Wall Day, Wear A Banana Split Day, Yad Sdrawkcab Gnihtyreve Lleps... and Make Up Your Own Holiday Day.
- Shown inside are:
- In ElfQuest, the desert-dwelling Sun Folk celebrate the Festival of Flood and Flower.
- The Imitate Festival in a one-page gag of The Smurfs, where each Smurf must for a day imitate another Smurf. However, Papa Smurf isn't pleased that Jokey would choose to imitate him.
- Sadie Hawkins Day in Li'l Abner.
- Undocumented Features gave us such delightful Dantrovian holidays as "The Festival of the Fudge Sauce", "Terzayyl", and "The Day The Colonists From Earth Finally Understood."

- In The Keys Stand Alone: The Soft World, the Cloud Horn concert every hundred days on the Flying Island of Tipaan turns out to mark a Svenjaya holiday, though we never learn if the holiday has a name.
Films — Live-Action
- Vivian Stanshall, Sir Henry at Rawlinson End (album and film versions): "To celebrate All Squids' Day there was a face-jumping competition at the Fool and Bladder."
- The Smurfs has the Blue Moon Festival, which takes place on the night of a blue moon.
- As well as Hogswatchnight, Discworld has the Soul Cake Days, which are a sort of cross between Hallowe'en (festivities include trickle-treating and sticky toffee rat on a stick) and Easter (the wizards used to roll boiled eggs down the Tump, and the Soul Cake Tuesday Duck lays chocolate eggs). Unfortunately for the Soul Cake Tuesday Duck, it also marks the start of the duck-hunting season.
- Readers of the diaries and calendars will discover a vast range of other Discworld holidays, ranging from the Creator's Birthday and Patrician Day (28th April and 6th Grune respectively; see also the birthdates of Terry Pratchett and Stephen Briggs) to Treacle Pie Day (June 24, commemorating the burning of a Patrician who imposed an unpopular tax on washing lines). Some of them are only celebrated by the guild or organisation responsible for a particular diary; the Guild of Thieves celebrates Finder's Day, when the ancient rule of "finders, keepers" is in effect.
- Discworld, as described in Night Watch, also has May 25th, "Lilac Day", a remembrance for those lost in the "Glorious" Revolution of Treacle Mine Road. It's only honored by those who were actually there, who wear a sprig of lilac because that had been the identifying mark the revolutionaries used. Vimes, Sgt. Colon and Reg Shoe of the Watch all wear one, as does Vetinari, although Vimes never really thought to ask him about his involvement in the revolution until nearly the end of Night Watch.
- As established in Feet of Clay, the 4th of Grune is the day when Ankh-Morpork has a big fireworks display to celebrate the end of the Ankh-Morpork Civil War. Given the date, it's a clear reference to the Fourth of July in the States, but they burn Stoneface Vimes in effigy, so it's also Guy Fawkes Night.
- Yobta’ Yupma’ in Star Trek: Klingon Empire, AKA the harvest festival. It’s mostly observed by farmers and natives of farming worlds, and isn’t widely known or celebrated by the rest of the Klingon Empire. Then there's the Andorian Spring Water Festival, as seen in the Star Trek: Deep Space Nine Relaunch.
- P.C. Hodgell's Chronicles of the Kencyrath has, in addition to celebrating the turns of the seasons and solstices, an intercalary day that does not appear on calendars. This is called the Feast of Fools in Tai-tastigon, and is a holiday of lawlessness and excess; in the Kencyr military academy, Tentir, this is the Day of Misrule, where the normal rules of the college do not apply and anyone who snatches the scarf from around a cadet's or officer's neck can command them. In addition, the Tastigon celebrate, or more precisely fear, the Feast of Dead Gods, a night immediately after Autumn's Eve where gods that have lost their followers walk the streets, searching for prey or other things they desire.
- In Relativity, Gale City was going to have a Mardi Gras celebration but couldn't pull it off in time. They decided to move everything to May 5th for Cinco de Mayo, but they didn't want to abandon the original idea, so they combined the two holidays. "Cinco de Mardi Gras" was such a huge hit they decided to have one every year.
- In Alan Dean Foster's novelization of The Last Starfighter, Centauri mentions that Christmas is "a local holiday roughly corresponding to All-Ether Day on Rylos."
- Quark: Happy Number 11!
- Dinosaurs had "Refrigerator Day", an expy/parody of Christmas. It has elements of Thanksgiving and Hanukkah.

- Colonial Day in the re-imagined Battlestar Galactica.
- ALF has Fappiano, a cross between Thanksgiving and Christmas.
- The Day of the Dead (Brakiri holiday, not Mexican) in Babylon 5, is observed only once every 200 years.
- Rose Nylund from The Golden Girls reminisces about St. Olaf holidays: Everybody Hide the Corn Day, Hay Day, the Day of the Princess Pig, and the Day of the Wheat, when everybody came to town dressed as sandwiches.
- Star Trek: The Original Series episode "The Return of the Archons". The planet Beta 3 had the holiday called Festival, in which the population went totally berserk (destroying, raping, etc.) for 1 hour (the "Red Hour"), then returned to their normal placid demeanor. This was due to their mental conditioning by the computer Landru.
- Star Trek: Voyager gives us First Contact Day, on April 4th, celebrating humanity's first contact with extraterrestrial life.
- Also the Vulcan "holiday" of Kal Rekk: "A day of atonement, solitude and silence," according to Tuvok. In the same conversation between Tuvok and Neelix, they discuss the ancient pagan festival of Rumarie, which apparently consisted of "barely clothed Vulcan men and women, covered in slippery Rillan grease, chasing one another." Tuvok says, "That has not been observed for a millennium."
- Bobunk in Sabrina the Teenage Witch. Falling each year on the third Saturday of November, it is the celebration of cats, food, liquor, food with liquor in it, and food shaped like cats. It's too bad that Salem accidentally deleted it...
- The pilot of Firefly opens on "Unification Day," a yearly celebration of the Alliance's victory during the civil war some years previous. Captain Reynolds, having fought on the losing side of said civil war, likes to celebrate it by starting a Bar Brawl.
- The Legend Of Dick And Dom has Garlic Tuesday, a dey to celebrate all that is smelly. It turns out that this is fictional in-universe as well, having been made up to torment Prince Dick when he was little.
- The 30 Rock episode "Leap Day" transforms leap day (February 29) from non-holiday into full-blown, commercialized, Christmas-esque bash with established traditions and traditional holiday characters. Liz is the only character who had never previously known Leap Day was such a big deal.
- Eureka has "Feynman Day", the genius equivalent of April Fools Day.
- One episode of Buffy the Vampire Slayer includes a banner celebrating Gurnenthar's Ascendance, which apparently occurs around the same time as Christmas.
- The100 has "Unity Day"
- Malcolm in the Middle: The "Ida's Dance" episode had Saint Grotus's Day from The Old Country. Parts of the celebrations include making a giant and terrible tasting tart with layers corresponding to the groups of people that Grotus slaughtered and a particularly dangerous version of Tinikling that involves sharp blades.
- Kingdom of Loathing uses a mixture of real-world and fictional holidays, to go with its fictional calendar: The Festival of Jarlsberg (New Years Day), St. Sneaky Pete's Day (St. Patrick's Day), Oyster Egg Day (Easter), Generic Summer Holiday (Summer Break, more or less, rather than any specific day), and Dependence Day (Fourth of July aka Independence Day) circulate around the calendar along with real-world holidays like Valentines Day and Halloween. Borderline cases such as Labór Day and Arrrrbor Day also exist.
- CAPSLOCK DAY in Billy Vs SNAKEMAN
- World of Warcraft has over a dozen seasonal events, most coinciding approximately with similar real world holidays

After receiving all of his gifts, Old Nick realizes he received many duplicates of gifts, so he sells them off for incredibly low prices!
- Splatoon: Splatfests are Inkopolis's special holidays. They occur every now and thennote , and during those times normal online gameplay is put on hold in favor of Splatfest Battles, which are battles that pit teams of two thematically opposed sides against each other for the chance to win Super Sea Snails. Additionally, they take place at night with special truck-top concerts by the Squid Sisters, with plenty of Inklings in attendance.
- Homestar Runner likes to refer to Christmas as Decemberween.
- In The Adventures of Dr. McNinja, Dr. McNinja and his family celebrate "Katanaka", which commemorates their Irish ancestors' original victory over pirates. It's observed on Thanksgiving so they can get off work too.
- In Monsterful we get the "Monster unity day" instead of Halloween, a day where peace and unity of all monsters is celebrated by dressing as other monster species, which is quite normal considering the setting of the comic is a monster-only world.
- In Triquetra Cats, the Antreyki celebrate Go, a harvest festival style holiday that combines elements of Halloween, Thanksgiving, and Christmas. The main symbol of the holiday is a pumpkin carved with the family symbol topped with an evergreen wreath and harvest fruits a la a cornucopia.

- In Death Note: The Abridged Series (kpts4tv), as a result of the MadLibs contest the cast celebrates "I'm Not Going To Take It Anymore Day."
- In Ultra Fast Pony, it's a recurring joke that these holidays don't have consistent names. So, in "Utter Lunacy", they celebrate a night that's known either as Halloween, Scaremas, or Scary Give Candy Night. And in "Pirate Shipping" the day is called Heartsgiving or Love Dependence Day.
- Video Game High School has L33tmas, a combination of pretty much every holiday you can think of.
- Whacking Day in The Simpsons.

- Clam Day in Family Guy.
- An episode of Daria had the eponymous character run into anthropomorphic holidays - including Valentines Day, St. Paddy's Day, Halloween, and Guy Fawkes Day. As it was primarily an American (MTV, at that) series, most viewers probably thought the last one was fictional. It's not.
- Or is it, as Britons generally recognize Bonfire Night?
- Not a national holiday as such, but certainly recognised on November 5th, over 400 years after the event it celebrates. But so soon after Halloween (in its current form, pretty much reimported from the USA) and involving burning a human effigy on a bonfire you can argue note the tradition it really celebrates goes back a lot further than 1605.

- My Little Pony: Friendship Is Magic has both expies of Earth holidays with Nightmare Night (Halloween) and Hearts and Hooves Day (St. Valentine's Day) and its own original holidays like the Summer Sun Celebration and Winter Wrap-Up. Hearth's Warming Eve kind of straddles the line by being obviously a Christmas expy of sorts in practice if not so much in terms of actual backstory, which makes it more of a country founding celebration.
- Starfire of Teen Titans once attempted to celebrate a "festival of friendship" from her home planet Tameran, but it didn't quite take with the rest of the team.
- The first episode of Marvel Mash-Up shows Spider-Man and Iceman celebrating "Flying Car Parts Day".

- In another episode, there is "Hit a Duck in the Face with a Lemon Meringue Pie" Day. When, unlike other characters, Roy won't settle for hitting Wade just once, Wade writes a letter to the Congress asking for a Holiday to hit roosters with mud and it gets passed the same day the pie one. Roy and Wade go so far Orson decides to punish them. Roy and Wade then get the Congress to pass a Holiday to paint pigs purple.
- Mike, Lu & Og has the Albonquetinians celebrate various holidays of their own, such as Lady Hewitt Smythe Day (celebrated with an elephant croquet match), All Foodstuff's Eve (an expy of Thanksgiving) and the First Day of Spring (where a chosen individual ears a giant nose over his/her head and leads the islanders in smelling every flower on the island).
- In one episode of The Doozers they learn the origins of Spookypalooza, the Doozer Creek counterpart to Hallowe'en.
- Ren and Stimpy had Yak Shaving Day. The celebration involved decorating the house with disposable diapers, filling your boots with coleslaw, and leaving a bowl of hot lather by the bathroom sink.

- The Smurfs has Rainbow Day, in which the Smurfs celebrate the appearance of a rainbow in the sky on a specific day of the year. There's also the Feast Of Plenty, which is the closest thing they have to Thanksgiving, the Firefly Festival, in which a Smurf must go to the Great Swamp to light a torch with the Foxfire to light up a firefly pinata before the end of the second day, and the infamous Hug-A-Smurf Day which Grouchy hates. Of course, there's every Smurf's least favorite holiday, Unhappiness Day, where Unhappiness Is Mandatory for a full day.
- Donkey Kong Country has the Kongo Bongo Festival of Lights, which is basically half related to Christmas, half a truce between Kongs and Kremlings.
- Barbie: Life in the Dreamhouse had its third TV special set on Sisters' Fun Day, on which the sisters of Malibu participate in various family-bonding activities.

Holidays Made Up by a Character:
Anime & Manga
- Laff-A-Lympics #13 has the fictional holiday National Prune Yogurt Day. It was made-up by the Rottens so they can deliver a booby-trapped box of prune yogurt to the Yogis, but Yogi (not knowing it's booby-trapped) delivers it to the Scoobies to commemorate the holiday, and Scooby-Doo delivers it back to the Rottens.
- In Peanuts, Schroeder didn't make up Beethoven's birthday per se, but he decided to turn it into an observance. It's December 16th, by the way.
Films — Live-Action

At one point they force their way in to an old woman's house to take some food and civilian clothes, and while they're there a sheriff's deputy drops by. Allen's character tells the deputy that he and the others are the woman's cousins, visiting her for "the holiday".
Deputy: (suspiciously) What holiday?
Allen: Did you ever hear of St. Abernathy's Day?
Allen: That's what we're here for.
- In The O.C., Seth's family celebrates "Christmukah," a combination of Christmas and Hannukah.
- In The Neighbors, Larry creates "Challoweenukah," a combination of Halloween and Hannukah.

- In the 30 Rock episode "Secret Santa," several of the show's staff invent the religion Verdukianism in order to get out of participating in Kenneth's Secret Santa exchange, and when Kenneth buys it, proceed to milk it for all it's worth:
Kenneth: Tonight is the Verdukian Holiday of Mouth Pleasures. Misters Rossitano, Spurloc, and Lutz must have three sausage pizzas followed by some flossing performed by a blonde virgin.
- In The Andy Griffith Show episode "Alcohol and Old Lace," two sweet old ladies who are operating a still (in a dry county) excuse themselves by explaining that the moonshine they sell people is meant not for "guzzling," but for "celebrating." Some of the holidays their customers suggest they may be celebrating include Sir Walter Raleigh Landing Day, Muhammed's birthday (observant Muslims are not supposed to drink alcohol), and National Potato Week.
Andy: Those aren't what you'd call legally recognized holidays.
- Neelix made up the celebration of Ancestors Eve in the Star Trek: Voyager episode "11:59".
- The only four people who celebrate Festivus are George Costanza's parents, George (unwillingly) ... and Kramer. The only purpose of the holiday seems to be to ensure that George had a Hilariously Abusive Childhood.
- The webcomic Ctrl+Alt+Del has Winter-een-mas, the January holiday invented by Ethan to celebrate video games. It turned into a surprise hit and even led to a brief kidnapping plot when a corporation wanted to take advantage of its popularity. Winter-een-mas is even celebrated in Real Life by some fans.
- Times Like This: Cassie attempts to create "Cattle Bell Day" in 1853 (this also doubles as a Shout-Out to Opie And Anthony).
- Gav and crew invent Agnostica in Nukees. Said holiday has been thoroughly defictionalized by fans of the strip and by the real Gav.
- In Idiotsitter, the Russel family celebrates Fight Day-Ocho de Octo:every year on the 8th of October, they beat each other with therapy bats to relieve tension. One such celebration is the plot of episode 5, "Fight Day."
- SF Debris presents two characters as having these, both in Star Trek: Voyager:
- Chakotay does this when his fictional Native American holiday requires him to take a shuttlecraft out of communications range, despite spacecraft not being a major feature of Native American tribal culture, and this distance being greater than could be achieved without leaving planet Earth. He guesses it's a way to avoid the planetary exploration the rest of the crew is engaged in, that supposedly involves cataloging a huge variety of gross creatures.
- Captain Janeway has a daily holiday named "Condescending Bitch Day", where she picks one member of the crew and makes them the focused target of her scorn. The usual target is Harry Kim, but anyone is viable.
- Doug has a subversion to it. Doug imagines his alter ego Quail-Man fighting a villain who wants to get rid of the weekdays. In the end, not only does he foil his plans, but creates a whole new weekday known as Funday in the process. This was accomplished by slowing the Earth's rotation, which somehow made the week eight days long instead of days longer.
- Bender made up Robanuka as an excuse for not working. The characters later decide to actually celebrate it — by "doing the robot dance", with Jewish music playing in the background.
- The episode also mentions before that he made up Robanza.
- The non-canon "Futurama Holiday Spectacular" episode also features Robanuka as one of the three main holidays celebrated along with X-Mas and Kwanaza. Of course, given what is established above, and the fact that the episode was not canon it doesn't change anything about the holiday being fictional.
- The Simpsons:
- When Homer makes up his own religion, he calls into work saying he can't come in because he's celebrating the "Feast of Maximum Occupancy" (he was in Moe's and read it off of a sign.)
- In "Flaming Moe's":

Advisor: Uh, sir, this is already Veterans' Day.
Mayor Quimby: It can be two things!
- In another episode Principal Skinner makes up "Scotchtoberfest" as part of a sting to catch Bart in the act of breaking the rules. Groundskeeper Willie is not pleased upon finding out that it was not in fact a real holiday.
Skinner: You fell for our sting, Bart! There's no such thing as Scotchtoberfest!
Willie: (distraught) There isn't?!? Ya used me, Skinner! Ya used me!!!
- His anger is perhaps understandable given the fact that the sting involved Bart subjecting him to a Marilyn Maneuver.
- Also, the greeting card business was upset over there being no holidays requiring greeting cards during the summer interval and they were losing money as a result, so what do they create as a solution? Love Day!
- SpongeBob SquarePants: "Hey everyone! It's Leif Erikson Day!" Which, it should be noted, is an actual holiday, though not of importance enough to be listed on a calendar.
- Starfire of Teen Titans once invented "Gorp Gorp, the Tameranian holiday of berating drapery" as a cover story. Given the fact that she comes from an alien culture, she pulls it off.
Starfire: Stupid Curtains!
- One episode revolves around the kids making up a holiday to fill the gap between Christmas and Valentine's Day. Ideas bandied about include "Pony Day", "There's Nothing to Do Today Day", "Igneous Rock Day", and "Give Me Candy Day", the last one thought up by Buster, where everyone in town specifically gives him (Buster) candy.
- There's also "Baxter Day", which Buster makes up for his mother to celebrate instead of Christmas, because it was stressing her out. It mostly consists of the two just hanging out and doing whatever they feel like.
- In The Amazing World of Gumball, Gumball is so depressed by post-Christmas blues that he invents a holiday for January. On Sluzzle Tag, one plays Grindcore carols, puts up barbed wire and guitars, and waits for Sluzzle Dude (who has a long beard, sneakers, and a leather jacket) to come up through the toilet to deliver gifts.
- Garfield and Friends: In one U.S. Acres episode, Roy makes up "National Tapioca Pudding" Day to pull a prank on Orson.
- Pinky and the Brain: In "Snowball", Brain tries to stop Snowball from taking over the world with a chain letter scheme by getting the government to acknowledge "Wink Martindale Day" to shut down the post offices.
