Why do we have April Fools’ Day?

Some customs, holidays, and traditions are very hard to trace to their beginnings. We just do it and can’t explain why? April fool’s Day, and how it originated, has explained in several ways, but no one is quite sure.
First of all, there is a day like our April fool’s Day in nearly all parts of the world. It is a day when practical jokes are played on friends and neighbors, like sending them on foolish errands or tricking them in to doing silly things.
It is believed that our April fool’s Day started with the French. When the calendar was reformed, the first nation to adopt the reformed calendar was France. Charles IX ordered, in 1564, that the year should begin with the 1st of January. Until then, New Year’s visits and the exchange of New Year’s gifts have been associated with the 1st of April.
Now, after Charles issued his decree, all this became associated with the 1st of January. But there were many people who objected to the change and refused to go along with it. The other people made fun of them for this.
