How did April Fools' Day get its name?

Answer 1

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.

One explanation is this: When the calendar was changed so that the year would begin on January 1 instead of March 25, some people stubbornly clung to the old tradition. Those who started their New Year celebration on the old date in March and continued into April were referred to as April fools.

Answer 2

It spread through Europe when a leader decided to change the calendar. but alot of people refused and alot of people still celebrate newyears on April 1st. so they were called April fools.
