April Fools' Day is celebrated in many countries on April 1st. It's not a holiday, but on this day, some people play tricks or funny jokes on friends, family members or other people to make the victim feel fool or stupid. In Spain we have a similar celebration on 28th December "Dia dels Inocents".
Traditionally, in the United Kingdom, Australia, New Zealand, and South Africa, the jokes finish at noon (12 o'clock), and someone who plays a trick after noon is called an "April Fool". In other countries ( France, Ireland, Italy, South Korea, Japan, Russia, The Netherlands, Germany, Brazil, Canada, and the U.S.A.), the jokes last all day.
