From France to Iceland to the United States, April Fools’ Day is celebrated with practical jokes and elaborate hoaxes.

April Fools' Day is celebrated worldwide, and many countries have their own unique pranks and jokes. In France, paper fish are often put on someone's back as a joke because the fish are said to be young and, therefore, easily caught. The prank is called the "April Fish," and those who get the fish placed on their backs are seen as gullible.

April Fools' Day is not recognized as a holiday in any country except for Odessa, Ukraine, where April 1 is an official city holiday. It is not a federal holiday in the U.S., although the tradition of playing pranks and jokes still goes on.
