If you’re in France on April 1st and someone sticks a paper fish on your back, don’t be alarmed—you’ve just become the target of a “Poisson d’Avril” prank. This quirky French custom is their version of April Fool’s Day, with a unique twist involving fish.
The Origins
“Poisson d’Avril” translates literally to “April Fish.” The practice dates back at least to the 16th century. One popular theory connects it to the calendar shift from Julian to Gregorian. When France officially adopted the Gregorian calendar in 1582, New Year’s Day moved from April 1 to January 1. However, not everyone got the memo immediately. Those who continued celebrating on April 1 were teased and playfully tricked, and over time, this evolved into the tradition of practical jokes we see today.
But why fish? Some theorize it’s because April 1 coincides with the tail end of the zodiac sign Pisces. Others suggest it relates to spring fishing bans, as newly hatched fish were considered naïve and easy to fool.
The Prank
The classic prank is simple: secretly attach a paper fish to someone’s back without them noticing. Children especially love this tradition, but adults happily participate too, often involving humorous jokes or fake news stories. Once the prank is discovered, everyone shouts, “Poisson d’Avril!”
This playful custom isn’t limited to individuals. French news outlets, brands, and even government agencies frequently join in with humorous headlines or mock press releases, much like companies around the world on April Fool’s Day.
Today, the custom remains good-natured fun. Chocolates and pastries shaped like fish fill bakery shelves, while parents, teachers, and kids create colorful paper fish to celebrate the day. It’s a harmless way to welcome spring, share a laugh, and keep a centuries-old tradition alive.
Final Thoughts
Poisson d’Avril reminds us that even in our routine-driven world, there’s always room for playfulness. So, if you find yourself in France on April 1, keep an eye on your back—you might just become part of the playful tradition.
