April Fools' Day! Are you ready! The online toolbox of the King of Pranks!

Every April 1st, is the Western folk traditional festival - April Fools' Day. April Fools' Day originated in France, in the sixteenth century, when France first adopted the Gregorian calendar (the current commonly used solar calendar), which was the new Christian calendar issued by Pope Gregory, with January 1st as the beginning of each year. But some people who were stuck in their old ways or hadn't heard about it still followed the old calendar, and on this day of April 1st, they sent gifts to celebrate the New Year. People who knew about this mocked the practices of these conservatives, and some smart and funny people even gave them fake gifts on that day, invited them to fake parties, and called those who fell for the tricks "April fools" or "hooked fish"! Since then, people joking and fooling around with each other on April 1st has become a popular custom in France. In the early 18th century, the custom of April Fools' Day spread to Britain, and was then brought to America by early British immigrants. Nowadays, many people around the world have the habit of celebrating April Fools' Day. The most typical activity of April Fools' Day is still mutual jokes, teasing each other in mischievous ways without being punished or criticized.
