For families with ties across borders, December 28 brings a mix of history and humor that’s worth understanding. If you’re sending money, calling relatives, or simply celebrating alongside loved ones in Mexico, Spain, or Latin America this time of year, knowing about Día de los Santos Inocentes helps you stay connected to the traditions that matter to them.
This guide breaks down the holiday’s origins, how it’s celebrated today, and how it compares to the American tradition of April Fools’ Day.

What Is the Origin of Día de los Santos Inocentes?
Día de los Santos Inocentes, or the Day of the Holy Innocents, has been part of the Catholic Church calendar since at least 485 AD. The day commemorates a dark moment in biblical history: the Massacre of the Innocents, when King Herod ordered the killing of young male children in Bethlehem in an attempt to eliminate the infant Jesus, according to the Gospel of Matthew. These children are considered the first Christian martyrs, and the Church originally set aside December 28 as a solemn day of remembrance .
So how did a day honoring a tragedy become a day for pranks? Historians point to a few contributing factors. According to donQuijote.org (2024), the shift toward a festive tone may be linked to pre-Christian winter celebrations like the Roman Saturnalia, when social hierarchies were temporarily turned upside down and jokes that would normally be inappropriate were permitted. The holiday’s declining theological importance over time, combined with the double meaning of the word “inocente”—which can mean both spiritually innocent and naive or gullible—likely helped push the day toward its modern, playful identity.
How Do People Celebrate Día de los Santos Inocentes?
Today, Día de los Santos Inocentes is best known as a day of pranks, called inocentadas. Common traditions include:
- Swapping ingredients: A classic prank involves replacing sugar with salt in the kitchen, catching someone off guard at breakfast or dinner.
- Paper cutouts: People pin small paper figures called monigotes onto the backs of unsuspecting friends or family members, similar to the “kick me” sign pranks popular in the United States.
- Fake stories: Friends and family invent elaborate, convincing tales designed to fool loved ones—only to reveal the joke later.
- Media hoaxes: Major newspapers, radio stations, and TV networks in Colombia, Spain, and Mexico have a long history of running fabricated news stories on December 28, later retracted or revealed as jokes.
When someone successfully falls for a prank, the trickster traditionally shouts, “¡Inocente, inocente!” Some regions use a longer rhyme: “Inocente palomita que te dejaste engañar, sabiendo que, en este día, en nadie debes confiar”—roughly translated as “Innocent little dove who let yourself be fooled, knowing that on this day you shouldn’t trust anyone”.

What Regional Traditions Exist Around This Holiday?
Celebrations vary by country, each adding its own local flavor to the holiday:
- Colombia: News networks air blooper reels known as los descaches, showcasing on-air mistakes from the past year. In the city of Pasto, Día de los Santos Inocentes also kicks off the Blacks and Whites’ Carnival with an event called Arcoíris en el Asfalto, where participants create colorful chalk drawings in the streets.
- Spain: The town of Ibi holds Els Enfarinats, a festival featuring a mock battle fought with flour and eggs.
- Venezuela: Some regions celebrate with Fiesta de los Locos, where participants dress in costumes and masks.
- Rural traditions: In some rural communities, a custom known as “innocent loans” persists, though it’s becoming less common. On this day, people borrow money or items from neighbors with no obligation to return them, and the lender who agrees is jokingly considered “innocent”.
Día de los Santos Inocentes isn’t limited to Spanish-speaking countries, either. The holiday is also observed in the Philippines due to centuries of Spanish colonial influence.
How Does Día de los Santos Inocentes Compare to April Fools’ Day?
For American readers, the easiest way to understand Día de los Santos Inocentes is to think of it as a cultural cousin to April Fools’ Day. Both holidays share a central theme: harmless pranks followed by a lighthearted reveal. But there are a few key differences worth noting.
First, the timing is different. Día de los Santos Inocentes falls on December 28, right in the middle of the Christmas and New Year season, while April Fools’ Day lands on April 1. Second, the origins diverge. Día de los Santos Inocentes traces back to a specific religious commemoration dating to the fifth century, while the origins of April Fools’ Day are less certain. One theory suggests it’s possibly linked to the 16th-century adoption of the Gregorian calendar, when the start of the new year shifted from around April 1 to January 1. Finally, Día de los Santos Inocentes carries a layer of religious and historical weight that April Fools’ Day simply doesn’t have, since the former is rooted in mourning before it became a celebration.
Interestingly, the holiday has even made its way into American pop culture. A 2009 episode of the ABC sitcom Modern Family titled “Undeck the Halls” featured the Día de los Santos Inocentes tradition, introducing the custom to a wider American audience.

How Can Families and Brands Respectfully Observe This Holiday?
If you have family, friends, or business connections tied to Mexico, Spain, or Latin America, acknowledging Día de los Santos Inocentes can be a meaningful way to show cultural awareness and respect. Here are a few guidelines to keep in mind:
- Keep pranks lighthearted. The spirit of the day is playful mischief, not harm. Stick to harmless jokes, like the classic sugar-for-salt swap, rather than anything that could cause real distress or financial confusion.
- Avoid misleading claims about money or health. Because the holiday involves fake news as a tradition, it’s especially important for brands, media outlets, and individuals to steer clear of hoaxes involving financial information, health advice, or urgent personal matters. A joke that causes real confusion or fear can undermine trust.
- Remember the day’s origins. Before the pranks, Día de los Santos Inocentes commemorates a solemn and tragic event. Approaching the holiday with some awareness of its history shows genuine cultural respect rather than treating it as a novelty.
- Celebrate connection, not just comedy. For many families, this day is also an opportunity to gather, share stories, and stay connected across generations and borders. Supporting those connections, whether through a phone call, a visit, or sending remittances to loved ones during the holiday season, matters just as much as the jokes themselves.
Keeping Your Loved Ones Connected, Wherever They Celebrate
Understanding traditions like Día de los Santos Inocentes is one small way to feel closer to family and culture, no matter where in the world you are. For many people in the United States with ties to Mexico, Spain, or Latin America, the holiday season is also a time to send support home, whether that’s for a gift, a celebration, or everyday needs.
