愚人節是大家互相開玩笑，用假話捉弄對方節日。沒人知道這個節日時怎么開始的，但是很多人認為是起源于法國。

In the 16 th century, people celebrated New Year's Day from March 25 to April 1. In the mid—1560s King Charles IX changed it from March 25 to January 1. But some people still celebrated in on April 1, so others called them April Fools.
16世紀，人們慶祝新年是從3月25日到4月1日，到了16世紀中期，查理四世國王把新年改為每年的1月1日到3月25日。可是一些因循守舊的人反對這種革新，依然按照舊歷固執地在4月1日這一天送禮品，慶祝新年。主張改革的人對這些守舊者的做法大加嘲弄。

Each country celebrates April Fools' Day differently. In France, people call the April Fools “April Fish”. They tape a paper fish to their friends' backs to fool them. When he or she finds this , they shout “April Fish!”
每個國家慶祝愚人節的方式都不相同。在法國，被愚弄的人成為“上鉤的魚”。人們把用紙剪裁成的魚貼在朋友的背后，當朋友們發現時，人們就大喊：“上鉤的魚”。

In England, people play jokes only in the morning. You are a “noodle” if someone fools you. In Scotland, April Fools' Day is 48 hours long. They call an April Fool “April Gowk”. Gowk is another name for a cuckoo bird.
在英國，愚人節時，大家只是在早上互相開玩笑。如果你被愚弄了，你就會被成為“面條”。在蘇格蘭，愚人節會持續48個小時，被愚弄的人被稱為“四月布谷鳥”。

在美國，4月1日，大家互相開玩笑，用假話捉弄對方。他們會指著你的鞋子說：“鞋帶開了”，如果你真的相信了，向下看自己的鞋子，你就成了四月傻瓜。
