愚人節(jié)，又稱愚人節(jié)，是每年4月1日慶祝的節(jié)日。它起源于歐洲，追溯到16世紀。有很多版本的愚人節(jié)的起源故事，下面是其中一個版本。

故事發(fā)生在16世紀的法國。當(dāng)時，法國國王查理九世頒布了一項法令，規(guī)定新年將于4月1日開始慶祝，而不是過去的4月1日。然而，許多人并不知道這項法令，繼續(xù)慶祝新年的舊日期。

有一些人決定開玩笑，他們將愚人節(jié)定為“假新年”，并在這一天開展各種愚弄行動，包括惡作劇和捉弄朋友等。這些人被稱為“愚人”，因為他們沒有遵守法律規(guī)定的新年日期。

愚人節(jié)逐漸流行開來，傳播到其他歐洲國家，最終成為了全球性的節(jié)日。今天，人們在愚人節(jié)仍然會互相開玩笑和捉弄，以紀念這個有趣的節(jié)日。

The April Fool's Day, also known as the All Fools' Day, is a holiday celebrated on April 1st every year. It originated in Europe and dates back to the 16th century. There are many versions of the origin story of April Fool's Day, and here is one of them.

The story takes place in 16th century France. At that time, King Charles IX issued a decree that the new year would be celebrated on April 1st instead of the previous date. However, many people did not know about this decree and continued to celebrate the new year on the old date.

Some people decided to play a prank and declared April 1st as 'false new year,' and began various foolish actions on this day, including practical jokes and tricks on friends. These people were called 'fools' because they did not follow the legal new year date.

April Fool's Day gradually became popular and spread to other European countries, eventually becoming a global holiday. Today, people still play pranks and tricks on each other on April Fool's Day to commemorate this fun holiday.
