why does april fools day exist
Still others believe April Foolsâ Day got its start because of the adoption of a new calendar in 1582. Many ancient cultures celebrated New Yearâs Day around April 1.In 1582, Pope Gregory XIII ordered the use of a new calendar, known as the Gregorian calendar, which celebrated New Yearâs Day on January 1.hese people continued to celebrate New Yearâs Day on April 1. Eventually, other people began to make fun of these backward âfoolsâ by sending them to look for things that did not exist (called a âfoolâs errand â) or tricking them into believing something false.
