愚人节起源于法国。1564年，法国首先采用新改革的纪年法——格里历(即目前通用的阳历)，以1月1日为一年之始。但一些因循守旧的人反对这种改革，依然按照旧历固执地在4月1日这一天送礼品，庆祝新年。主张改革的人对这些守旧者的做法大加嘲弄。聪明滑稽的人在4月1日就给他们送假礼品，邀请他们参加假招待会.并把上当受骗的保守分子称为“四月傻瓜”或“上钩的鱼”。从此人们在4月1日便互相愚弄，成为法国流行的风俗。18世纪初，愚人节习俗 传到英国，接着又被英国的早期移民带到了美国。

April Fool's Day originated in france. In 1564, French first adopted the Gregorian calendar reform -- the new calendar (the Gregorian calendar that is now common), with January 1st as the beginning of the year. But some follow the beaten track who opposed this reform, still according to stubbornly cling to the old calendar in April 1st this day to send gifts to celebrate the new year. Advocates of the reform of the old person practices of much mockery. Smart funny in April 1st will give them false gift, invited them to false reception. And deceived conservatives as "April fool" or "bait fish". Then people will fool each other in April 1st, France has become a popular custom. At the beginning of eighteenth Century, April Fool's day practices reached England, followed by the British in the early immigrants to the America.
