April Fools' is celebrated in many countries all over the world, including Poland, Scotland and even Iran.

The French call the day Poisson d’Avril, or ‘April Fish’. French children will often tape a picture of a fish on to the back of their friends and wait for them to realise. This is also the case in Italy.

In Scotland, April Fools’ Day used to be called Huntigowk Day – gowk being Scots for a cuckoo or a foolish person.

Traditionally people were sent on a foolish errand to deliver a sealed message reading ‘Dinna laugh, dinna smile. Hunt the gowk another mile’.

In Iran pranks have been played on April 1 since 536 BC. The day is the 13th day of the Persian New Year, and is called Sizdah Bedar. Families and friends will mark the new season by spending the afternoon outside with food, games and jokes.
