The Complete Guide to February's Obscure Holidays
February is short but dense — 58 obscure holidays packed into 28 (or 29) days, more per day on average than any other month on this calendar. Valentine's Day gets the headline, but the month runs a full second track underneath it: Groundhog Day folklore, a cloned sheep, the discovery of Pluto, and a specifically Swedish curling holiday.
This guide walks through all 58, day by day, with a bit of history or context for each one and a link to the full write-up — complete fun facts, ways to celebrate, and sourcing — on its own page.
Why does February have so many obscure holidays?
Two clusters stand out. There's a real romantic-calendar cluster around Valentine's Day itself — Galentine's Day, Singles Awareness Day, and Ferris Wheel Day (George Ferris's actual birthday) all sit within a few days of it. And there's a genuine science-and-history cluster: Darwin Day, Pluto Discovery Day, Dolly the Sheep Day, the first steam locomotive journey, and National Periodic Table Day are all tied to specific, dated, real events rather than invented observances — a higher ratio of “this actually happened” holidays than most other months.
How to use this guide
Holidays are grouped by date below. Each entry gets a short original write-up — not a repeat of the fact sheet — plus a link to the full holiday page if you want the deeper dive: complete fun facts, ways to celebrate, and sourcing.
February 1
🔑 Change Your Password Day
A cybersecurity nudge dressed up as a holiday: over 80% of data breaches trace back to weak or stolen passwords, a fairly damning statistic for something this fixable. Pairing a strong password with two-factor authentication does more for your security than changing the password itself ever will. Full holiday page →
🍫 National Dark Chocolate Day
The bar for “dark” is at least 70% cocoa solids, roughly the threshold where the flavanol antioxidants linked to improved blood flow start showing up in meaningful amounts. The plant itself, Theobroma cacao, translates from Greek as “food of the gods.” Full holiday page →
February 2
🥞 Crepe Day
Known in France as La Chandeleur, tied to the Presentation of Jesus at the Temple, but the crêpe tradition has its own superstition layered on top: flip one one-handed while holding a coin in the other, and it's supposed to bring good fortune for the year. Full holiday page →
🐿️ Groundhog Day
Punxsutawney Phil's official accuracy rate, as claimed by his own fan club, doesn't hold up against actual meteorological records, which put him closer to 30–40% — barely better than a coin flip. The tradition traces back to European Candlemas weather lore, where a badger or hedgehog did the shadow-watching before groundhogs took over in America. Full holiday page →
February 3
🥕 Carrot Cake Day
Carrots were a medieval baking workaround, not a health food choice — used to sweeten desserts back when sugar was expensive and hard to get. Its modern reputation as a “healthier” cake dates specifically to a 1970s marketing push, cream cheese frosting and all. Full holiday page →
🎶💔 The Day the Music Died Day
Marks the actual 1959 plane crash that killed Buddy Holly, Ritchie Valens, and the Big Bopper — and the seating arrangement that put them on the plane is its own grim story: Valens won his seat in a coin toss, and the Big Bopper, sick with the flu, took Waylon Jennings' spot. Jennings was Holly's bass player and would have been on that flight otherwise. Full holiday page →
February 4
🥣 National Homemade Soup Day
Soup is older than most food categories get credit for — archaeological evidence puts it back to roughly 6000 BC, involving boiled hippopotamus bones and taro. The word itself comes through French from a Germanic root meaning “sop,” as in bread dipped into liquid. Full holiday page →
✉️ Thank a Mailman Day
The USPS delivers to over 160 million addresses, which puts the daily route of an average mail carrier in a different category of physical endurance than most desk jobs. Organized mail delivery isn't a modern idea, either — the Egyptians and Romans both ran their own systems thousands of years ago. Full holiday page →
February 5
🍫 Chocolate Fondue Day
Despite the Swiss reputation, chocolate fondue as most people know it was popularized in 1960s New York by Swiss restaurateur Konrad Egli — an import that got rebranded as tradition. The original fondue, dating to the 18th century, was savory and cheese-based; chocolate came along much later. Full holiday page →
🍫 World Nutella Day
Founded in 2007 by an American blogger, not by Ferrero itself — the company only formally backed the day in 2015, eight years after fans started it without them. Nutella's actual origin traces to wartime Italy, when chocolate rationing forced Pietro Ferrero to stretch a small amount of cocoa with a lot of hazelnuts. Full holiday page →
February 6
🥢 National Chopsticks Day
Chopsticks started as cooking tools in ancient China over 4,000 years ago, long before they became eating utensils. About a third of the world's population uses them as their primary utensil today, and the regional differences are real — Japanese chopsticks are short and pointed, Chinese ones longer and blunt, Korean ones flat and metal. Full holiday page →
🍦 National Frozen Yogurt Day
Despite its 1970s American boom, frozen yogurt actually dates to the 1930s as a soft-serve product — it just took decades and a self-serve, build-your-own-cup model in the late 2000s to really catch on. Full holiday page →
February 7
🍝 National Fettuccine Alfredo Day
Alfredo di Lelio invented the dish around 1908 in Rome for his own pregnant wife, and the original recipe has no cream in it at all — the creaminess comes purely from emulsifying butter with Parmigiano-Reggiano. It went global only after Mary Pickford and Douglas Fairbanks discovered it in Rome and brought it back to Hollywood. Full holiday page →
⚛️ National Periodic Table Day
Commemorates a lesser-known precursor: John Newlands' 1865 “Law of Octaves,” which noticed a periodicity in element properties years before Mendeleev's version became the standard. There are 118 confirmed elements today, with new ones still occasionally synthesized. Full holiday page →
February 8
🪁 National Kite Flying Day
Kites started in China over 2,800 years ago as military signaling devices, not toys — the recreational use came much later. Benjamin Franklin's famous 1752 lightning experiment used one, and the largest kite ever flown, launched in Kuwait, measured over 11,000 square feet. Full holiday page →
🥔 National Potato Lovers Day
The potato is the third-largest food crop in the world by consumption, behind only rice and wheat, and the Andes region alone is home to over 4,000 native varieties. The average American eats about 110 pounds of potatoes a year. Full holiday page →
February 9
🍕 National Pizza Day
Americans eat roughly 350 slices of pizza every second, adding up to about 3 billion pizzas a year. The very first pizzeria, Antica Pizzeria Port'Alba, opened in Naples in 1738 — more than two and a half centuries before pepperoni became America's default topping. Full holiday page →
🛀📖 Read in the Bathtub Day
Ancient Roman baths doubled as intellectual gathering spaces, so the pairing of bathing and reading has a longer pedigree than it looks. Modern waterproof e-readers have mostly solved the one real obstacle — a soggy paperback — that used to make this holiday more theoretical than practical. Full holiday page →
February 10
☂️ National Umbrella Day
Invented in China over 4,000 years ago primarily for sun protection, not rain — the word itself comes from the Latin umbra, meaning shade. It took 18th-century Englishman Jonas Hanway years of public ridicule to normalize carrying one for rain. Full holiday page →
⚓️ Plimsoll Day
Marks the birth of Samuel Plimsoll, whose campaign against dangerously overloaded “coffin ships” led directly to the 1876 Merchant Shipping Act and the mandatory Plimsoll Line — the marking on a ship's hull that still limits how heavily it can be loaded today, a century and a half later. Full holiday page →
February 11
💡 National Inventors' Day
Timed to Thomas Edison's birthday, who held over a thousand patents in his lifetime — a number that makes most modern inventors look underemployed by comparison. Reagan didn't formally proclaim the day until 1983, more than a century after Edison started patenting things. Full holiday page →
👕 White T-Shirt Day
Marks the end of the 44-day Flint Sit-Down Strike against General Motors in 1937, a pivotal labor moment where workers occupied the factories rather than picketing outside them — a tactic that made it much harder for the company to bring in strikebreakers. Full holiday page →
February 12
🐒 Darwin Day
Darwin shares his exact birthdate with Abraham Lincoln — both born February 12, 1809, an odd historical coincidence for two men who reshaped very different parts of the 19th century. His five-year voyage on HMS Beagle, especially the time in the Galápagos, is what actually built the observations behind On the Origin of Species. Full holiday page →
🍮 Plum Pudding Day
Despite the name, traditional plum pudding contains no actual plums — “plum” was historically just a catch-all word for dried fruits like raisins and currants. It traces back to a 14th-century savory porridge called frumenty, which evolved over centuries into the flaming, brandy-doused dessert served today. Full holiday page →
February 13
❤️ Galentine's Day
Invented, quite literally, by a fictional character: Leslie Knope on Parks and Recreation coined it in a 2010 episode, describing it simply as “ladies celebrating ladies.” It's one of the rare holidays on this calendar with a traceable single origin — a TV writers' room, not folklore. Full holiday page →
📻 World Radio Day
UNESCO proclaimed this in 2011, choosing February 13th specifically because it's the anniversary of United Nations Radio's founding in 1946. Despite decades of newer media, radio still reaches an estimated 4 billion people worldwide. Full holiday page →
February 14
🎡 Ferris Wheel Day
Built to rival the Eiffel Tower, which had stolen the show at the 1889 Paris Exposition — the original Ferris wheel debuted at the 1893 Chicago World's Fair standing 264 feet tall with room for 2,160 riders across 36 cars. Today's record holder, Dubai's Ain Dubai, is more than three times as tall. Full holiday page →
❤ Valentine's Day
Traces back to layered, tangled origins — Roman fertility festivals, multiple early Christian martyrs named Valentine — that have almost nothing to do with the roughly 1 billion cards exchanged worldwide today. In Japan the custom runs opposite to the West: women give chocolate to men on this day, and men reciprocate a month later on White Day. Full holiday page →
February 15
🍬 Gumdrop Day
Traditional gumdrops got their firm, chewy texture from gum arabic, a natural resin tapped from acacia trees — modern versions have mostly switched to gelatin or pectin instead. The name first shows up in print in the mid-1800s. Full holiday page →
🖤 Singles Awareness Day
The unofficial abbreviation, S.A.D., is a deliberate joke about timing — landing the day right after Valentine's Day, functioning as an intentional counterweight to all that romantic pressure. Most people mark it with friends or personal hobbies rather than anything resembling loneliness. Full holiday page →
February 16
😠 Do a Grouch a Favor Day
Purely a modern, internet-calendar invention with no traceable founder — its entire premise is doing something nice for the specifically grumpy people in your life. Oscar the Grouch gets cited constantly as the unofficial mascot. Full holiday page →
🇱🇹 Lithuanian Independence Day
Marks the 1918 Act of Re-establishment, signed by twenty members of the Council of Lithuania after the country had spent over a century absorbed into the Russian Empire following the 1795 partition. Full international recognition took years after the signing, given the chaos across the region after World War I. Full holiday page →
February 17
🥬 Cabbage Day
A member of the same plant family as broccoli, cauliflower, and kale, with a cultivation history stretching back to ancient China and Egypt. Sauerkraut, its fermented form, was standard provisioning for sailors specifically because it prevented scurvy on long voyages. Full holiday page →
❤ Random Acts of Kindness Day
Run by an actual nonprofit, the Random Acts of Kindness Foundation, built on research showing that acts of kindness measurably boost happiness and reduce stress for both the giver and the receiver. The bar for participation is deliberately low — holding a door counts as much as anything bigger. Full holiday page →
February 18
🍷 National Drink Wine Day
Winemaking's earliest confirmed evidence comes from the country of Georgia, dated to around 6000 BCE — older than written language itself. There are over 10,000 distinct wine grape varietals worldwide, though commercial production leans on only a few dozen. Full holiday page →
🔭 Pluto Discovery Day
Marks Clyde Tombaugh's 1930 discovery at the Lowell Observatory, made when he was just 24 — Pluto held planet status for 76 years before its 2006 reclassification as a dwarf planet. Its name came from an 11-year-old English schoolgirl, Venetia Burney, who suggested the Roman god of the underworld. Full holiday page →
February 19
🍫🌿 National Chocolate Mint Day
The “After Eight,” one of the flavor combination's most iconic products, was introduced by Rowntree & Co. in 1962 — its thin, square shape was as much a branding decision as the flavor itself. Full holiday page →
🤝 National Tug-of-War Day
Was an official Olympic event from 1900 to 1920, a fact that surprises most people who only know it as a playground game. Good teams rely on synchronized rhythm and technique as much as raw strength, which isn't obvious from watching a match for the first thirty seconds. Full holiday page →
February 20
🐾 Love Your Pet Day
Backed by real data: roughly 66% of U.S. households now own a pet, and interacting with them measurably raises oxytocin levels and lowers blood pressure. The longevity record belongs to Bobi, a Portuguese Rafeiro who lived to 31 years and 165 days. Full holiday page →
🧁 Muffin Day
English and American muffins are almost unrelated foods sharing one name — English muffins are yeast-leavened and griddle-cooked, while American muffins are quick breads baked in individual molds. The earliest known written muffin recipe appears in a 1747 cookbook. Full holiday page →
February 21
🚂 First Steam Locomotive Journey Day
Marks Richard Trevithick's 1804 run on the Pen-y-darren tramway in Wales, hauling 10 tons of iron and 70 passengers over 9 miles in about four hours — the literal birth of rail travel. The engine itself was too heavy for the era's brittle cast-iron rails, which kept breaking under it. Full holiday page →
🍯 National Sticky Bun Day
Strongly associated with Pennsylvania Dutch cooking, where the buns are sometimes called “schnecken” — German for “snails,” a nod to their spiral shape. The caramel glaze bakes on the bottom of the pan and only ends up on top once the whole thing gets flipped after baking. Full holiday page →
February 22
🐑 Dolly the Sheep Day
Marks the 1997 announcement of Dolly the sheep, the first mammal ever cloned from an adult cell rather than an embryonic one — a genuine scientific first that reopened the entire bioethics conversation. She was named for Dolly Parton, since the source cell came from a mammary gland. Full holiday page →
🍹 National Margarita Day
Nobody actually agrees on who invented the margarita — competing claims put its origin in both Mexico and the US sometime in the 1930s or '40s, and none of them have ever been settled. What isn't disputed is the recipe: tequila, lime juice, orange liqueur, salted rim. Full holiday page →
February 23
🥌 Curling Day (Sweden)
Sweden's national curling day sits on top of a sport with real Olympic pedigree — full medal status arrived at the 1998 Nagano Games, though it appeared as a demonstration sport decades earlier. The oldest known curling stones trace back to 16th-century Scotland. Full holiday page →
🍌 National Banana Bread Day
Banana bread's popularity surge traces specifically to the Great Depression, when using overripe bananas instead of throwing them out actually mattered. It also needed a technical assist — widely available baking soda and powder in the 1930s, which made “quick breads” like this possible in the first place. Full holiday page →
February 24
🌮 National Tortilla Chip Day
Credited to Rebecca Webb Carranza, who in the late 1940s started cutting and frying tortillas her family's Los Angeles tortilleria would otherwise have thrown away — turning food waste into an entire snack category. Full holiday page →
🍸 World Bartender Day
The first cocktail recipe book, Jerry Thomas's “The Bar-Tender's Guide,” was published in 1862 — Thomas is still commonly called the father of American mixology. Flair bartending, the juggling-and-flipping style, owes its modern popularity almost entirely to the 1988 Tom Cruise movie “Cocktail.” Full holiday page →
February 25
🤖 International Bionic Man Day
Marks the 1973 premiere of “The Six Million Dollar Man” pilot movie — its catchphrase, “better, stronger, faster,” outlived the show itself by decades. The distinctive bionic sound effect was created simply by slowing down a recording of a reverberating noise. Full holiday page →
🥣 National Clam Chowder Day
The earliest known printed recipe dates to 1751, in the Boston Evening-Post — chowder has been a fixture of American cuisine since before the country existed. The New England-versus-Manhattan feud is old and genuinely heated: Maine's legislature once considered a bill to outlaw tomatoes in chowder entirely. Full holiday page →
February 26
🧦 Left Sock Day
The average person reportedly loses about 15 socks a year, which is enough of a pattern to have spawned genuine jokes about “sock monsters” living inside washing machines. This holiday specifically honors the leftover single sock, rather than the mismatched-pair trend some people wear intentionally on other days. Full holiday page →
🥜💚 Pistachio Day
Pistachios aren't technically nuts at all — botanically they're the seed of a drupe, the same fruit category as a peach, just with the flesh mostly gone. Cultivation dates back roughly 8,000 years in the Middle East, and the green color comes from retained chlorophyll. Full holiday page →
February 27
🐻❄️ International Polar Bear Day
Polar bears are classified as marine mammals, not land animals, given how much of their life depends on sea ice. Their fur isn't actually white — it's transparent and hollow, scattering light in a way that just looks white, while the skin underneath is black to better absorb heat. Full holiday page →
🍓 National Strawberry Day
Botanically, a strawberry isn't a true berry at all — it's an “aggregate accessory fruit,” and it's the only common fruit that carries its roughly 200 seeds on the outside rather than inside. California alone grows about 75% of the strawberries produced in the US. Full holiday page →
February 28
💐 Floral Design Day
Marks the 1947 founding of the Rittner School of Floral Design in Boston, one of the longer-running institutions behind an art form that goes back to ancient Egyptian decoration. Japanese ikebana takes the opposite approach from most Western arranging — built around discipline and negative space rather than sheer volume of flowers. Full holiday page →
🧵 Nylon Invention Day
Marks Wallace Carothers' 1935 breakthrough at DuPont — the first fiber ever synthesized entirely from chemical compounds, not derived from a plant or animal at all. When nylon stockings launched in 1940, millions of pairs reportedly sold out within hours. Full holiday page →
February 29
🐸 Leap Day
People born on this date are genuinely called “leaplings,” and the statistical odds of it happening are about 1 in 1,461. The old “Ladies' Privilege” tradition, where women were customarily allowed to propose marriage on this date, traces back to an Irish legend involving St. Bridget and St. Patrick. Full holiday page →
🦸♂️ Superman's Birthday
DC Comics assigned Superman this date deliberately, making him a fictional leapling despite his real-world debut landing in April 1938's Action Comics #1. By the internal logic of the joke, he ages only one year for every four that pass on Earth. Full holiday page →

About this guide
This guide is part of the Obscure Holiday Calendar project — the same database that powers the iOS and Android apps and the individual holiday pages on this site. It exists to give a single, readable overview of an entire month at once, instead of requiring 58 separate page visits.
