Problems With This Explanation

There are at least two difficulties with this explanation. The first is that it doesn't fully account for the spread of April Fools' Day to other European countries. The Gregorian calendar was not adopted by England until 1752, for example, but April Fools' Day was already well established there by that point. The second is that we have no direct historical evidence for this explanation, only conjecture, and that conjecture appears to have been made more recently.

Constantine and Kugel

Another explanation of the origins of April Fools' Day was provided by Joseph Boskin, a professor of history at Boston University. He explained that the practice began during the reign of Constantine, when a group of court jesters and fools told the Roman emperor that they could do a better job of running the empire. Constantine, amused, allowed a jester named Kugel to be king for one day. Kugel passed an edict calling for absurdity on that day, and the custom became an annual event.

"In a way," explained Prof. Boskin, "it was a very serious day. In those times fools were really wise men. It was the role of jesters to put things in perspective with humor." This explanation was brought to the public's attention in an Associated Press article printed by many newspapers in 1983. There was only one catch: Boskin made the whole thing up. It took a couple of weeks for the AP to realize that they'd been victims of an April Fools' joke themselves.

Spring Fever

It is worth noting that many different cultures have had days of foolishness around the start of April, give or take a couple of weeks. The Romans had a festival named Hilaria on March 25, rejoicing in the resurrection of Attis. The Hindu calendar has Holi, and the Jewish calendar has Purim. Perhaps there's something about the time of year, with its turn from winter to spring, that lends itself to lighthearted celebrations.

Observances Around the World

April Fools' Day is observed throughout the Western world. Practices include sending someone on a "fool's errand," looking for things that don't exist; playing pranks; and trying to get people to believe ridiculous things.
 

The French call April 1 Poisson d'Avril, or "April Fish." French children sometimes tape a picture of a fish on the back of their schoolmates, crying "Poisson d'Avril" when the prank is discovered.

[In Scotland, April Fool's Day is a two day celebration, with one of the days being devoted specifically to pranks involving the buttocks. This special day is thus referred to as “Taily Day.” The butts of these jokes are known as April 'Gowk', another name for cuckoo bird. The origins of the "Kick Me" sign can be traced back to the Scottish observance.

In England, jokes are played only in the morning. Fools are called 'gobs' or 'gobby' and the victim of a joke is called a 'noodle.' It was considered back luck to play a practical joke on someone after noon.

In Rome, the holiday is known as Festival of Hilaria, celebrating the resurrection of the god Attis, is on March 25 and is also referred to as "Roman Laughing Day."

In Portugal, April Fool's Day falls on the Sunday and Monday before lent. In this celebration, many people throw flour at their friends.

The Huli Festival is celebrated on March 31 in India. People play jokes on one another and smear colors on one another celebrating the arrival of Spring.]
