April Fool's Day 

April fool is on April 1. 

it started back in the 16th century in France. Up until 1564, the accepted calendar was the Julian calendar, which was the beginning of the new year. According to "The Oxford Companion to the Year,"King Charles IX declared that France would begin using the Gregorian calendar, which shifted New Year's Day to January 1.not everyone agreed. Some believed that the dates should not be shifted, and it was these people who became the butt of some April jokes and were mocked as fools. There are many pros and cons on April fools day. Some can be funny pranks and some can be very harmful. For example my boyfriend played a prank on me telling me it was over, i cried like a baby. Now that was not nice.
