Prima aprilis

April Fool's Day is on 1 April every year in many countries. On this day, practical jokes (or April Fools) are played on friends and family. The jokes are done to embarrass them. In some countries, April Fool's only last until noon, and if someone plays a joke after, they are an April Fool. "April Fool's Day's past and gone, You're the fool for making one."

April Fool's is Fred and George Weasley's birthday, the twins from the popular series Harry Potter. The twins are well known for being pranksters.

In France and Italy, children and adults traditionally tack paper fish on each other's back as a trick and shout "april fish!" in their local language ("poisson d'avril!" and "pesce d'aprile!" in French and Italian respectively).
