April 1st Is Poisson d’avril Day🐟

Did you know that April 1st isn’t just about jokes and pranks everywhere in the world?
In France, it’s a day filled with laughter, tradition—and fish! 🐟

Every spring, I’m reminded of a French picture book I used to read to my children when they were little. It’s one of our favorites—and it always makes me smile. The title is Un poisson en avril, which translates to “A Fish in April.”

The story is gentle and heartwarming. A little boy draws a fish, and with each page, the fish is passed from one person to another, traveling along with the fresh spring air. Why do I think of this book in April? Because in France, April 1st is Poisson d’avril—literally, “April Fish” Day!

April Fools’ Day? Not quite the same!

Growing up in Japan, I always thought of April 1st as April Fools’ Day—a day for telling harmless lies. That impression, I think, came from American culture. But around the world, this day is celebrated in different ways.

In France, it’s a bit more playful and whimsical—especially for children. That’s where Poisson d’avril comes in.

Where did Poisson d’avril come from?

There are several theories about the origins of Poisson d’avril, but the most widely accepted one dates back to the 16th century.

At the time, people in France celebrated the New Year between March 25 and April 1. But in 1582, King Charles IX introduced a new calendar and declared January 1 as the official start of the year. Since there was no internet or mass communication, not everyone got the message right away—and some continued to celebrate the new year in April.

These people were playfully mocked with fake gifts, and over time, the practice evolved into a day of jokes and pranks.

Why a fish?

Another theory ties Poisson d’avril to Lent (Carême), the Christian fasting period before Easter. Since people refrained from eating meat during this time, fish became a symbolic food. It’s believed that this connection gave rise to the idea of using fish as a humorous symbol for the day.

So yes—that’s why it’s all about fish!

Paper fish on your back? Classic French fun!

In France today, Poisson d’avril is especially popular among children. A classic prank is to secretly tape a paper fish to someone’s back without them noticing.

When my children were little, they loved doing this. Both my husband and I were often caught with paper fish on our backs! 😅 Naturally, their schoolmates got in on the fun, too.

In France, chocolate fish and spring treats

In France, there’s no traditional meal for this day, but since it often coincides with the Easter season, you might find chocolate fish or other fish-shaped treats in stores. Wrapped in colorful foil, these little chocolates make perfect seasonal gifts for children.

Why not fish for dinner?

So, in the spirit of Poisson d’avril, why not celebrate with a fish-themed dinner?
You’ll find plenty of delicious spring-inspired fish recipes on Umami. Add a little French flair to your table, and finish the day with a smile—and a tasty bite. 🐟😊
