The Mexican festival of Los Santos Inocentes (the innocent saints) is similar to our April Fools’ Day. It is celebrated on December 28th and it was originally to recall the innocent children killed by King Herod.
It was known at first as a day when you could borrow something and not have to return it, so people would try to trick others into lending them something valuable on that day. Nowadays it is a day for practical jokes in general.
