You’re walking down a street in Madrid or Mexico City on December 28th and suddenly realize there is a paper cutout of a little person stuck to your back. People are giggling. You've been "monigoted." This is El Día de los Inocentes, or Holy Innocents Day. Most travelers and even some expats living in Spanish-speaking countries assume it’s just a copycat version of April Fools’. It isn't. Not even close. While the modern vibe is definitely about pranks and laughter, the roots of this day are surprisingly dark, tied to a biblical massacre that makes the transition to "jokes and stickers" feel a bit jarring if you think about it too hard.
Honestly, the energy is different than the April 1st tradition you might be used to in the US or UK. It’s more communal. In Spain and throughout Latin America, the media gets involved with fake news stories that actually look real, and entire towns sometimes participate in massive, bizarre festivals that involve flour fights or elaborate costumes. It’s a day where the "innocent" person is the one who gets fooled, but it’s all in good fun—mostly.
The Weird History You Probably Didn't Know
So, where did this actually come from? If you look at the Catholic calendar, December 28th commemorates the Matanza de los Inocentes. According to the Gospel of Matthew, King Herod the Great ordered the execution of all male children under the age of two in Bethlehem. He was terrified of the "Newborn King" the Magi had told him about. He wanted to eliminate any threat to his throne.
It's grim. Really grim.
Over the centuries, the way the Church and the public observed this day shifted. During the Middle Ages, there was a popular tradition called the "Feast of Fools" (Fiesta de los Locos). It was a brief period where the social order was flipped upside down. Altar boys would act as bishops. Low-ranking officials would give orders to their superiors. It was chaotic. Eventually, the Church tried to tone down the wilder pagan-adjacent celebrations, and somehow, that festive, subversive spirit merged with the day of the Holy Innocents. The "innocence" of the children was reinterpreted as the "naivety" of someone who falls for a prank.
By the time we get to the modern era, the mourning aspect has almost entirely disappeared from the public consciousness, replaced by the bromas (jokes). But even today, you’ll still see some people attend Mass in the morning before heading out to pull a fast one on their friends.

How the Pranks Actually Work Today
The most iconic symbol of El Día de los Inocentes is the monigote. It’s a simple paper doll cutout. The goal is to sneak up behind someone and pin it to their back without them noticing. If you manage to do it, they are the inocente for the rest of the day, or at least until they look in a mirror.
But it goes way beyond paper dolls.
Media and "Fake News"
In Spain and Mexico, major newspapers and TV news stations join in. Think of it like the BBC’s famous spaghetti tree prank from the 50s, but every single year. You might see a headline claiming a major football star is retiring to become a monk or that the government is banning salt. In 2021, some outlets joked about massive, ridiculous changes to COVID regulations that had people panicking for a split second before they checked the date. You have to take every headline with a massive grain of salt on the 28th.
Salt in the Sugar Bowl
In households, the pranks are classic. Replacing sugar with salt in the coffee is the gold standard. Or changing the time on someone's alarm clock. It’s simple stuff, but because the holiday falls right between Christmas and New Year’s, everyone is already in a relaxed, festive mood, making them easier targets.
Regional Celebrations That Get Wild
If you think a paper doll is underwhelming, you need to look at how specific towns in Spain handle the day. It gets theatrical.

In the town of Ibi, in Alicante, they celebrate Els Enfarinats. It is basically a giant battle involving flour, eggs, and firecrackers. A group of men takes over the town under a "new justice" system, fining people for silly reasons and then donating that money to charity. The visuals are insane—everyone is completely white from the flour, and it looks like a beautiful, messy war zone.
Then there is the Fiesta de los Locos in Jalance. Or the Danza de los Locos in Fuente Carreteros. These aren't just jokes; they are deep-seated cultural performances with specific costumes and traditional dances that have been passed down for generations. In some parts of Mexico, it’s common to borrow something from a friend on this day. The "prank" is that you don't have to give it back right away. There’s even a little rhyme: "Inocente palomita que te dejaste engañar, sabiendo que en este día nada se puede prestar" (Innocent little dove who let yourself be fooled, knowing that on this day, nothing should be lent).
If you lend someone money on December 28th in Mexico City, don't expect to see it again until the 29th. Or maybe ever.
The Business Side of Being "Innocent"
Interestingly, this day has a real impact on retail and media engagement. While it's not a "shopping holiday" like Black Friday, the sheer volume of social media engagement for brands that pull successful pranks is huge. Marketing teams in Latin America spend weeks prepping their "fake" product launches.
However, there is a fine line.

Experts in communication often warn brands about the "Backfire Effect." If a joke is too believable—like a fake price drop or a change in service terms—it can actually frustrate customers. The best brand pranks on El Día de los Inocentes are the ones that are clearly absurd but just "maybe" enough to make you double-tap. For example, a fast-food chain claiming they are launching a "taco-scented perfume." It's obviously fake, but it gets people talking.
Common Misconceptions to Clear Up
- Is it a public holiday? No. In most countries, businesses and schools are open. It’s a working day, which actually makes the pranks better because you can catch your coworkers off guard.
- Is it only in Spain? Nope. It’s huge across Mexico, Argentina, Colombia, Venezuela, and Chile. Even the Philippines has its own version (Niños Inocentes), though the "pranking" aspect there has faded significantly in recent years in favor of more religious observances.
- Is it exactly like April Fools? Sorta, but the timing is the key. Since it’s tucked into the Guadalupe-Reyes marathon (the period from Dec 12 to Jan 6 in Mexico), it’s part of a much larger spiritual and social season.
Why We Still Do This
There's something human about needing a "cheat day" for the truth. Life is heavy. The end of the year is usually full of reflection, stress about the future, and holiday burnout. El Día de los Inocentes acts as a pressure valve. It allows us to be silly, to play like children (which brings the holiday's name back around in a full circle), and to not take the news so seriously for twenty-four hours.
Tips for Surviving December 28th
If you find yourself in a Spanish-speaking country on the 28th, keep your guard up. Here is how you handle it:
- Check your back. Seriously. Reach back there right now. If you feel paper, you’ve been got.
- Verify the news. If you see a headline that seems too good (or too weird) to be true, check the date. Don't go sharing "Breaking News" on WhatsApp until you're sure it's not a broma.
- Don't lend anything. If a friend asks to borrow 20 bucks or your car keys, just smile and say, "Maybe tomorrow."
- Taste-test your food. Before you take a giant bite of that cake or a swig of that coffee, do a quick "salt check."
- Lean into it. The worst way to handle being the inocente is to get mad. The whole point is to admit you were naive for a second. Laugh it off.
The best way to experience the day is to participate. Buy some paper, cut out some monigotes, and see how many people you can "tag" at the office or the dinner table. Just remember that the goal is fun, not cruelty. The best pranks are the ones where the "victim" laughs just as hard as the person who pulled it off.
What to Do Next
If you're planning to celebrate, start by looking up local events if you're in a city like Madrid, Mexico City, or Bogota. Check out the Gala Inocente, Inocente on Spanish TV (RTVE), which is a massive charity telethon that uses pranks on celebrities to raise millions for children's charities. It’s a great example of how the day’s "grim" origins have been transformed into something genuinely helpful for the community. Finally, if you're a content creator or a business owner with a Spanish-speaking audience, start brainstorming your "fake" announcement at least a week in advance—just make sure it's absurd enough that you don't end up answering angry customer service emails all the next day.
