April 1 is known in many countries as the Day of Lies. Although it has already become a tradition in some countries, many do not know where this day comes from. If you are in this group of people, it's time to learn.

April Fool's Day was once celebrated as New Year's Day, but with the change of calendar from Julian to Gregorian, in 1582 by Pope Gregory XIII, New Year's Day was set for January 1st. However, some people continued to lie to themselves and celebrate this day on April 1, while others mocked them by calling them "stupid". But this is not the only explanation.

According to Professor Joseph Boskin, this day originated during the reign of Constantine, when a joker named Kugel told the emperor that he could better run the empire. Constantine took this with a laugh and allowed Kugel to become emperor for one day, on April 1, which Kugel declared the Day of Lies. This explanation was published in 1983 by the Associated Press, but there was a problem. Boskin had fabricated this to make a joke about April 1st. It took the Associated Press some time to realize that this was a lie and to apologize to readers.

Today April 1st is celebrated in Europe as the Day of Lies, when people make different tricks and jokes with each other.
