When is April Fools’ Day 2025? What are the Origins of this Silly Holiday?

When is April Fools’ Day?

April Fools’ Day occurs annually on April 1. In 2025, it falls on a Tuesday. 

“April Fool’s Day” vs. “April Fools’ Day”

Don’t get fooled. The correct way to write this day is “April Fools’ Day.” It’s been April Fools’ Day since the 1800s. Why? If you know your apostrophes, then you know that putting the apostrophe after an S means it’s a plural. There isn’t just one fool on this day; there are many pranksters running around! 

Origin of April Fools’ Day—How did it all start?

The origin of April Fools’ Day is unknown, but theories say it started hundreds of years ago. Some theorize that the idea of April Fools’ Day dates back to ancient Rome and a festival called Hilaria held at the end of March where people would dress up in disguises and mock or imitate others.

Many folklorists believe it may go back to 16th-century France. Charles IX decreed that the new year would begin on January 1. Back in those times, New Year’s Day was around Easter and spring festivals were celebrated with a whole week of partying. Some folks were slow to catch on to the change, continuing to celebrate the new year. They quickly became the victim of jokes and pranks, including having paper fish put on their backs and labeled a poisson d’avril, meaning “April fish.”

In Scotland, people would send others on phony errands called “hunting the gowk,” as well as pin fake tails or kick me signs on the unsuspecting. 

Some believe that the term “All Fools” was probably meant as a deliberate stab at All Saints (November 1) and All Souls (November 2) Day.

April Fools’ Day and the Vernal Equinox (Think Spring!)

The timing of April Fools’ Day is suspiciously close to the Vernal Equinox…

It is the time of year when Mother Nature is known to play tricks on us all with unpredictable changes to the weather, including:

• In 1923, temperatures reached –34°F in Bergland, Michigan.
• In 1960, up to 10 inches of heavy snow fell in eastern South Dakota, causing some highways to close due to difficulty plowing the heavy snow.
• In 1997, a blizzard from Maryland to Maine resulted in power outages and roads impassable. East Jewett, New York, recorded 37 inches, and 25.4 inches fell in Boston, Massachusetts.

Famous (and Infamous) April Fools’ Day Pranks in History

April Fools’ Day is all about getting someone to fall for a prank or a made-up story. But some take it a step further:

• On April 1, 1905, Berliner Tageblatt, a German newspaper, reported that thieves dug a tunnel under the U.S. treasury and stole $268 million in silver and gold.
• In 1957, the BBC aired a story on how Swiss farmers were experiencing a bumper crop for spaghetti, complete with a video of people harvesting noodles from trees. Here’s the video:

• In 1983, Boston University professor Joseph Boskin created a story about the origin of April Fools’ Day when speaking to an AP reporter. He said the day originated when Roman Emperor Constantine agreed to let one of his jesters, “Kugel,” become “king for a day.” Boskin, of course, made up the entire story.
• In 1985, Sports Illustrated published a fictitious story by George Plimpton about a never-before-heard-of pitching prospect by the name of Sidd Finch, who could throw a baseball 168 miles per hour.
