Despite being a widely celebrated tradition for centuries, the origins of April Fool’s Day remain uncertain.
According to historical accounts, this practice involves misleading others on April 1 with “invented or false, usually fantastic or fantastic tales, stories or information”.
One widely discussed explanation links this tradition to calendar reforms in 16th-century France.
In 1564, King Charles IX introduced a new system that set January 1 as the beginning of the year, leading some people to continue celebrating the New Year on April 1, which became the subject of ridicule and mockery.
Another theory dates back to the 16th century and refers to a failed currency reform associated with the Diet of Augsburg.
According to later reports, speculators who had expected changes on April 1 were left scoffing when the improvement did not occur.
Other possible origins lie in literature and religion. Some historians point to medieval Europe, where pranks were already common, while others suggest links to Biblical tales or Geoffrey Chaucer’s 14th-century work The Canterbury Tales.
Records as early as 1618 reference the phrase “sending in April”, indicating that the practice had already been established.
Despite many theories, historians agree that it has no single definitive origin.
