Unlike most of the other nonfoolish holidays, the history of April Fool's Day, sometimes called All Fool's Day, is not totally clear. There really wasn't a "first April Fool's Day" that can be pinpointed on the calendar. Some believe it started from celebrations involving the first day of spring.
The closest point in time that can be identified as the beginning of this tradition was in 1582, in France. Back then the year ended on March 31st. New Year's Day was then April 1st. When the calendar was changed under Charles IX, the calendar we use today was introduced, and New Year's Day was moved to January 1.
However, communications being what they were in the days when news traveled by foot, many people did not receive the news for several years. Other people refused to accept the new calendar and continued to celebrate the new year on April 1. These backward folk were called "fools" by most people. They were teased, and were often sent on "fools errands" or were made the butt of other practical jokes.
These practical jokes, over time, grew into a tradition of prank-playing on the first day of April. The tradition eventually spread to England and Scotland in the eighteenth century. It was later introduced to the American colonies of both the English and French. April Fool's Day thus developed into an international fun fest, with different nationalities specializing in their own brand of humor at the expense of their friends and families.
In Scotland, for example, April Fool's Day is actually celebrated for two days. The second day is devoted to pranks. The origin of the "kick me" sign can be traced to these pranks.
Pranks performed on April Fool's Day range from the simple, (such as saying, "Your shoe's untied!"), to the elaborate. Setting a roommate's alarm clock back an hour is a common gag. Whatever the prank, the trickster usually ends it by yelling to his victim, "April Fool!"
Practical jokes are a common practice on April Fool's Day. Sometimes, elaborate practical jokes are played on friends or relatives that last the entire day. The news media even gets involved. For instance, a British short film once shown on April Fool's Day was a fairly detailed documentary about "spaghetti farmers" and how they harvest their crop from the spaghetti trees.
April Fool's Day is a "for-fun-only" observance. Nobody is expected to buy gifts or to take their "significant other" out to eat in a fancy restaurant. Nobody gets off work or school. It's simply a fun little holiday, but a holiday on which one must be aware, for he may be the next April Fool!
