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.

16世纪，罗马天主教教派决定将欧洲的年历改由1月1号开始，取代原来的4月1号。一些人一时无法适应这个新规定，而被其他人称为无知或固执。他们就成为第一批“四月愚人”。
