April Fool

April Fools' Day or All Fools' Day is an annual custom on 1 April consisting of practical jokes and hoaxes. Jokesters often expose their actions by shouting "April Fools!" at the recipient. Mass media can be involved in these pranks, which may be revealed as such the following day. The custom of setting aside a day for playing harmless pranks upon one's neighbour has been relatively common in the world historically.

Origins

Although the origins of April Fools’ is unknown, there are many theories surrounding it.

A disputed association between 1 April and foolishness is in Geoffrey Chaucer's '' The Canterbury Tales'' (1392). In the " Nun's Priest's Tale", a vain cock Chauntecleer is tricked by a fox on "Since March began thirty days and two," i.e. 32 days since March began, which is 1 April. However, it is not clear that Chaucer was referencing 1 April since the text of the "Nun's Priest's Tale" also states that the story takes place on the day when the sun is "in the sign of Taurus had y-rune Twenty degrees and one," which would not be 1 April. Modern scholars believe that there is a copying error in the extant manuscripts and that Chaucer actually wrote, "''Syn March was gon''". If so, the passage would have originally meant 32 days after March, i.e. 2 May, the anniversary of the engagement of King Richard II of England to Anne of Bohemia, which took place in 1381.

In 1508, French poet Eloy d'Amerval referred to a '' poisson d'avril'' (April fool, literally "April's fish"), possibly the first reference to the celebration in France. Some historians suggest that April Fools' originated because, in the Middle Ages, New Year's Day was celebrated on 25 March in most European towns, with a holiday that in some areas of France, specifically, ended on 1 April, and those who celebrated New Year's Eve on 1 January made fun of those who celebrated on other dates by the invention of April Fools' Day. The use of 1 January as New Year's Day became common in France only in the mid-16th century, and that date was not adopted officially until 1564, by the Edict of Roussillon, as called for during the Council of Trent in 1563. However, there are issues with this theory because there is an unambiguous reference to April Fools' Day in a 1561 poem by Flemish poet Eduard de Dene of a nobleman who sends his servants on foolish errands on 1 April, predating the change. April Fools' Day was also an established tradition in Great Britain before 1 January was established as the start of the calendar year.

In the Netherlands, the origin of April Fools' Day is often attributed to the Dutch victory in 1572 in the Capture of Brielle, where the Spanish Duke Álvarez de Toledo was defeated. "''Op 1 april verloor Alva zijn bril''" is a Dutch proverb, which can be translated as: "On the first of April, Alva lost his glasses". In this case, "bril" ("glasses" in Dutch) serves as a homonym for Brielle (the town where it happened). This theory, however, provides no explanation for the international celebration of April Fools' Day.

In 1686, John Aubrey referred to the celebration as "Fooles holy day", the first British reference. On 1 April 1698, several people were tricked into going to the Tower of London to "see the Lions washed".

Although no biblical scholar or historian is known to have mentioned a relationship, some have expressed the belief that the origins of April Fools' Day may go back to the Genesis flood narrative. In a 1908 edition of the ''Harper's Weekly'' cartoonist Bertha R. McDonald wrote:

Long-standing customs

United Kingdom

In the UK, an April Fool prank is sometimes later revealed by shouting "April fool!" at the recipient, who becomes the "April fool". A study in the 1950s, by folklorists Iona and Peter Opie, found that in the UK, and in countries whose traditions derived from the UK, this continues to be the practice, with the custom ceasing at noon, after which time it is no longer acceptable to play pranks. Thus a person playing a prank after midday is considered the "April fool" themselves.

In Scotland, April Fools' Day was originally called "''Huntigowk Day''". The name is a corruption of "hunt the ''gowk''", ''gowk'' being Scots for a cuckoo or a foolish person; alternative terms in Gaelic would be ''Là na Gocaireachd'', "gowking day", or ''Là Ruith na Cuthaige'', "the day of running the cuckoo". The traditional prank is to ask someone to deliver a sealed message that supposedly requests help of some sort. In fact, the message reads "''Dinna laugh, dinna smile. Hunt the gowk another mile.''" The recipient, upon reading it, will explain they can only help if they first contact another person, and they send the victim to this next person with an identical message, with the same result.

In England a "fool" is known by a few different names around the country, including "noodle", "gob", "gobby", or "noddy".

Ireland

In Ireland, it was traditional to entrust the victim with an "important letter" to be given to a named person. That person would read the letter, then ask the victim to take it to someone else, and so on. The letter when opened contained the words "send the fool further".

Italy, France, Belgium, French-speaking areas

In Italy, France, Belgium and French-speaking areas of Switzerland and Canada, the 1 April tradition is often known as "April fish" (''poisson d'avril'' in French, ''april vis'' in Dutch or ''pesce d'aprile'' in Italian). Possible pranks include attempting to attach a paper fish to the victim's back without being noticed. This fish feature is prominently present on many late 19th- to early 20th-century French April Fools' Day postcards. Many newspapers also spread a false story on April Fish Day, and a subtle reference to a fish is sometimes given as a clue to the fact that it is an April Fools' prank.

Germany

In Germany, an April Fool prank is sometimes later revealed by shouting "April, April!" at the recipient, who becomes the "April fool".

Nordic countries

Danes, Finns, Icelanders, Norwegians and Swedes celebrate April Fools' Day (''aprilsnar'' in Danish; ''aprillipäivä'' in Finnish; ''aprilsnarr'' in Norwegian; ''aprilskämt'' in Swedish). Most news media outlets will publish exactly one false story on 1 April; for newspapers this will typically be a first-page article but not the top headline.

Poland (''Prima aprilis'')

In Poland, ''prima aprilis'' ("First April" in Latin) as a day of pranks is a centuries-long tradition. It is a day when many pranks are played: hoaxes – sometimes very sophisticated – are prepared by people, media (which often cooperate to make the "information" more credible) and even public institutions. Serious activities are usually avoided, and generally every word said on 1 April could be untrue. The conviction for this is so strong that the Polish anti-Turkish alliance with Leopold I signed on 1 April 1683, was backdated to 31 March. However, for some in Poland ''prima aprilis'' ends at noon of 1 April and ''prima aprilis'' jokes after that hour are considered inappropriate and not classy.

Ukraine

April Fools' Day is widely celebrated in Odessa and has the special local name Humorina - in Ukrainian Гуморина (''Humorina''). This holiday arose in 1973. An April Fool prank is revealed by saying "Первое Апреля, никому не верю" ("''Pervoye Aprelya, nikomu ne veryu''") - which means "First of April, I trust nobody" - to the recipient. The festival includes a large parade in the city centre, free concerts, street fairs and performances. Festival participants dress up in a variety of costumes and walk around the city fooling around and pranking passersby. One of the traditions on April Fools' Day is to dress up the main city monument in funny clothes. Humorina even has its own logo a cheerful sailor in a lifebelt — whose author was the artist Arkady Tsykun. During the festival, special souvenirs bearing the logo are printed and sold everywhere. Since 2010, April Fools' Day celebrations include an International Clown Festival and both celebrated as one. In 2019, the festival was dedicated to the 100th anniversary of the Odessa Film Studio and all events were held with an emphasis on cinema.

Spanish-speaking countries

In many Spanish-speaking countries (and the Philippines), "''Día de los Santos Inocentes''" ( Holy Innocents Day) is a festivity which is very similar to April Fools' Day, but it is celebrated in late December (27, 28 or 29 depending on the location).

Turkey

Turkey also has a custom of April Fools' pranks. Pranks and jokes are usually verbal and are revealed by shouting "Bir Nisan!" (April 1st!).

Iran

In Iran, it is called "''Dorugh-e Sizdah''" (lie of Thirteen) and people and media prank on 13 Farvardin ( Sizdah bedar) that is equivalent of 1 April. It is a tradition that takes place 13 days after the Persian new year Nowruz. On this day, people go out and leave their houses and have fun outside mostly in natural parks.
Pranks have reportedly been played on this holiday since 536 BC in the Achaemenid Empire.

Israel

Israel has adopted the custom of pranking on April Fools' Day.

Lebanon

In Lebanon, an April Fool prank is revealed by saying (which means "First of April Lie") to the recipient.

Pranks

A common prank is to carefully remove the cream from an Oreo and replace it with toothpaste, and there are many similar pranks that replace an object (usually food) with another object that looks like the object but tastes different such as replacing sugar with salt and vanilla frosting with sour cream. As well as people playing pranks on one another on April Fools' Day, elaborate pranks have appeared on radio and television stations, newspapers, and websites, and have been performed by large corporations. In one famous prank in 1957, the BBC
