Ever woken up on April 1st and immediately felt that low-level anxiety? You know the feeling. You’re checking your laces. You’re squinting at news headlines to see if they’re just a little too weird to be true. We’ve all been there. It’s a global phenomenon, but the weirdest part is that nobody can actually agree on how it started. Seriously.
People love a clear-cut answer. They want a "this happened on this date" kind of story. But when you look into the origins of April Fools Day, you realize it's less of a single event and more like a messy, centuries-long game of telephone.
The Calendar Theory: Blame the French?
The most common explanation you’ll hear involves 16th-century France. Back then, King Charles IX decided to get the country on the same page by adopting the Gregorian calendar. Before this, the New Year was often celebrated around the spring equinox, peaking on April 1st.
Imagine the chaos.
Some people didn't get the memo. News traveled slow—literally at the speed of a horse. Others were just stubborn. They kept celebrating in April. Those who had updated to the January 1st start date began mocking these "fools." They’d stick paper fish on their backs. Why a fish? In France, it’s called Poisson d’Avril. It refers to a young, easily caught fish—or a gullible person.
But here’s the kicker: this theory has holes. Historians have found references to April fooling that predate the 1582 calendar shift. It’s a convenient story, but it’s probably not the whole truth.
The Hilaria Connection
If we look further back—like, ancient Rome back—we find Hilaria. This was a festival celebrated at the end of March to honor Cybele, an ancient Greek mother goddess. People would dress up in masquerades. They’d mock everyone, even local officials. It was a day of total social inversion.

Essentially, it was a pressure valve for society. You get to act like an idiot for twenty-four hours so you can be a "productive citizen" the rest of the year.
Chaucer’s Possible Typo
Literature nerds often point to Geoffrey Chaucer and The Canterbury Tales from 1392. In the "Nun's Priest's Tale," there’s a line about a vain rooster being tricked by a fox on a date that seems to translate to April 1st.
Except, it might just be a typo.
Chaucer wrote "Syn March bigon thritty dayes and two." Most readers at the time probably understood this to mean 32 days after March began (May 3rd). But over time, people started interpreting it as March 32nd—otherwise known as April 1st. If the entire world started pranking each other because of a medieval clerical error, that’s actually the most April Fools thing ever.
Why Do We Still Do This?
Honestly, it’s about power. Not the big, scary kind, but the small, social kind. Pranking someone is a way of showing you're "in the know" while they aren't. It’s a test of social awareness.
In Scotland, the tradition was actually a two-day affair. They called it "Huntigowk Day." You’d send someone on a "sleeveless errand"—basically a fool's errand. They’d carry a message asking for help, but the message actually said, "Dinna laugh, dinna smile, hunt the gowk another mile." The recipient would then send the poor person to someone else further away. It was mean. It was funny. It was human nature.

The Great Media Pranks
By the 1900s, the origins of April Fools Day didn't matter as much as the scale of the pranks. The BBC is the undisputed heavyweight champion here. In 1957, they aired a segment about Swiss farmers harvesting spaghetti from trees.
Thousands of people called in.
They wanted to know how to grow their own spaghetti trees. The BBC’s response? "Place a sprig of spaghetti in a tin of tomato sauce and hope for the best."
Then you have the 1996 Taco Bell stunt. They took out full-page ads in major newspapers claiming they had bought the Liberty Bell to help reduce the national debt. They were going to rename it the "Taco Liberty Bell." People lost their minds. Even the White House press secretary at the time, Mike McCurry, got in on it, joking that the government was also selling the Lincoln Memorial to Ford and renaming it the "Lincoln-Mercury Memorial."
A Global Mess
It isn’t the same everywhere.
- India: The Holi festival involves throwing colored powder and playing jokes, though it usually falls in March.
- Spanish-speaking countries: They have Dia de los Innocentes (Day of the Holy Innocents) in December. It’s functionally the same thing—pranks and laughter—but with a totally different religious backstory.
- The Netherlands: They have their own specific reasons, often tied to the 1572 capture of the town of Brielle from Spanish forces.
The Psychology of the Prank
Why does it feel so good to trick someone? Evolutionary psychologists suggest it might be a way to build group cohesion. When we share a joke—even if it's at someone else's expense—we're establishing who is part of the "in-group."

Of course, in the age of "Fake News" and deepfakes, April Fools has changed. It's harder to pull off a prank when the actual news is already bizarre. Many brands have actually backed off from April Fools because the risk of a PR disaster is too high. If your "joke" looks too much like a real product failure, your stock price might actually take a hit.
How to Handle April 1st Like a Pro
If you’re planning on participating, there are unwritten rules. Don’t be that person who takes it too far.
- Know your audience. A prank on your best friend is different from a prank on your boss.
- Keep it "low stakes." If the prank costs someone money or ruins their day, it’s not a prank. It’s just being a jerk.
- The "Noon Rule." In many cultures, particularly in the UK, pranks are only supposed to happen before midday. If you play a trick in the afternoon, you are the fool.
- Verify everything. On April 1st, don't share a "breaking news" story until you've checked at least three different reputable sources.
The origins of April Fools Day might be murky, but the impulse is clear. We like to laugh. We like to see if we're smarter than the person next to us. And sometimes, we just like the excuse to be a little bit ridiculous.
Whether it started with a calendar change in France, a Roman festival, or a typo by a guy named Geoffrey, it’s here to stay. Just remember to check your shoes for saran wrap before you step outside.
Next Steps for April 1st Success
To make the most of the tradition without losing your friends, focus on "confusables" rather than "scares." The best pranks are the ones where the victim laughs as soon as the reveal happens.
- Audit your sources: Before April 1st, bookmark a few fact-checking sites like Snopes. They usually keep a running tally of corporate pranks as they happen.
- Plan "constructive" pranks: Consider the "office switch-up" where you replace someone's family photos with pictures of celebrities, or the "classic mouse prank" (a small piece of tape over the optical sensor of a computer mouse).
- Observe the "Poisson d'Avril": If you want to be historically accurate to the French roots, try the "Paper Fish" challenge. See how many people you can pin a small paper fish onto without them noticing. It’s harmless, traditional, and surprisingly difficult.
