Overview
- The annual prank day, which falls on Wednesday, April 1, 2026, is being previewed with lists of jokes and reminders to keep them light.
- Historians agree the roots are uncertain, with theories spanning a 16th-century French calendar change, medieval references, and ancient spring festivals.
- The calendar-shift story remains popular, though researchers also cite a 1561 Flemish poem and France’s poisson d’avril custom of placing paper fish on people’s backs.
- Media and brands have long joined the fun, from the BBC’s 1957 “spaghetti harvest” to Google’s recurring gags, with Volkswagen’s 2021 “Voltswagen” episode showing how hoaxes can mislead.
- This year’s roundups favor low-stakes tricks such as soap that will not lather, toothpaste-filled cookies, tape over a mouse sensor, frozen cereal, color-changing milk, or a balloon avalanche.
