Every year on April 1, people across the world celebrate April Fool’s Day by playing harmless pranks, sharing funny jokes, and surprising friends, family members and colleagues with clever tricks. What began as a light-hearted tradition centuries ago has now become a global social media event, with brands, celebrities and internet users joining in with viral posts and memes.

But why do we celebrate April Fool’s Day, and how did it begin? Here is a reader-friendly look at its history and some of the funniest pranks that captured attention online.

The exact origin of April Fool’s Day is still debated, and historians point to several possible explanations.

One popular theory links it to France in the 16th century. In 1582, King Charles IX adopted the Gregorian calendar, moving New Year celebrations from the end of March to January 1. Those who continued to celebrate the old New Year date around April 1 were mocked and called “April fools”.

Another theory traces the tradition to ancient spring festivals in Europe, where people marked the changing season with playful behaviour and role reversals.

Some also compare it to festivals such as Hilaria in ancient Rome, where people wore disguises and celebrated with jokes and laughter.

Though the exact beginning remains unclear, the spirit of harmless fun has remained the same through the centuries.

Earlier, April Fool’s Day pranks were mostly played among friends, in schools, homes or offices.

With the rise of television and newspapers, media houses also began publishing prank stories on April 1. Today, the tradition has moved strongly to social media platforms such as X, Instagram, Facebook and YouTube, where prank posts often go viral within minutes.
