The first day of April is known in England as April Fools' Day or All Fools' Day. The idea is to play tricks with other people, to try to make them believe things that are completely untrue. 1) Although most of the tricks are far from original or have been used for a long time, they succeed again and again.
The simplest jokes can involve children who tell each other that their shoelaces are undone. 2) Sometimes people are told that their jackets have been torn or they are sent on a false business errand. 3) They produce sensacional news on television, radio as well as in the press. 4) Those who continue to play jokes in the afternoon are April fools themselves.
Several theories have been put forward about how the tradition began. 5) So the origin of the "custom of making April Fools" remains uncertain and unknown.
