If it is the morning of April 1 and you see some money on the ground, perhaps you should think twice before you pick it up. It might have beengluedthere by someone keen to turn you into an “April fool.” Remember: It is the first day of April, a day when people around the world enjoy playing tricks on each other.
In the 16th century, the Roman Catholic Church decided that the calendar year in Europe would begin on January 1, instead of the original date of April 1. Some people were slow to accept the new rule, and others called them ignorant or stubborn. They became the first April fools.
The tradition of playing tricks on this day most likely started in France. Victims there were known as “April fish,” possibly due to the ease with which newborn fish could be caught in the spring. Nowadays, it is still a custom among French children to tie paper fish to each others’ backs on April 1.
