The first mention of this custom is a curt note in Aubrey: ‘Fooles holy day. We observe it on ye first of April. And so it is kept in Germany everywhere.(Aubrey, 1686, 1880: 10). It must have reached England from Germany or France in the mid-17th century, and quickly became very popular under the name All Fools' Day; 18th-century writers call it ‘universal’. At this period it was an adult amusement; people tried to trick one another into going on ridiculous errands, seeking nonexistent objects such as pigeon's milk or a biography of Eve's mother, and so on.Individual hoaxing of this kind grew rare among adults in the 19th century, but in recent decades impersonal media hoaxes have become popular; every year, press and television produce a crop of plausible, poker-faced absurdities ingeniously disguised as news items. On 1 April 1970 BBC radio broadcast a tribute to a non-existent scholar and philanthropist, in which various celebrities took part.The Times, abandoning its rule that hoaxes should be ignored, did report this one; readers were amused, not angry. The idea was increasingly imitated, for example by the Guardian's n1977 account of the delightful but imaginary island of Sans Serif.Children's tricks can be directed either against adults or against one another.Some are novel, as when some Bradford sixth-formers in 1970 advertised their school as being for sale, but most are traditional in form; they give false warnings and disconcerting news, and mock those who believe them, play simple practical jokes, send people on futile errands (Opie and Opie, 1959: 243-7). As with other children's customs, there is a time limit; anyone attempting a trick after midday is taunted:April Fool is gone and past,
You're the biggest fool at last.
April Fool's Day or All Fool's Day,holiday of uncertain origin, known for practical joking and celebrated on the first of April. Prior to the adoption of the Gregorian calendar in 1564, the date was observed as New Year's Day by cultures as varied as the Roman and the Hindu. The holiday is considered to be related to the festival of the vernal equinox, which occurs on Mar. 21. The English gave April Fool's Day its first widespread celebration during the 18th cent.April Fools' Day or All Fools' Day, although not a holiday in its own right, is a notable day celebrated in many countries on April 1. The day is marked by the commission of hoaxes and other practical jokesfriends, family members, enemies, and neighbors, or sending them on fool's errand, the aim of which is to embarrass the gullible. Traditionally, in some countries, the jokes only last until noon: like UK, Australia, New Zealand and Canada, someone who plays a trick after noon is called an "April Fool".Elsewhere, such as in Ireland, France, and the USA, the jokes last all day. Another origin is that April 1 was counted the first day of the year in France. When King Charles IX changed that to January 1, some people stayed with April 1. Those who did were called "April Fools" and were taunted by their neighbors.

One likely theory is that the modern holiday was first celebrated soon after the adoption of the Gregorian Calendar; the term referred to someone still adhering to the Julian Calendar which it replaced.In many pre-Christian cultures May Day.In the eighteenth century the festival was often posited as going back to the times of Noah.An English newspaper article published on April 13th, 1789 said that the day had its origins when he sent the raven off too early, before the waters had receded. He did this on the first day of the Hebrew month that corresponds with April.
