એપ્રિલ ફૂલ્સ ડે અથવા ઓલ ફૂલ્સ ડે તરિકે જાણીતો આ દિવસ, રજાનો દિવસ કે કોઈ પ્રખ્યાત તહેવાર ના હોવા છતાં ભારત સહિત ઘણા દેશોમાં પહેલી એપ્રિલનાં દિવસે બહોળા પ્રમાણમાં અલાયદી રીતે ઉજવવામાં આવે છે. આજના દિવસે લોકો પોતાના મિત્રો, કુટુંબીજનો, પડોશીઓ અને ક્યારેક દુશ્મનો સાથે રમૂજભરી ટિખળ કરે છે. સામાન્ય રીતે આ ટિખળમાં સામી વ્યક્તિને મૂર્ખ બનાવવાનો કે છોભી પાડવાનો મુખ્ય ઉદ્દેશ્ય હોય છે. પારંપરિક રીતે કેટલાક દેશોમાં આવી મજાક-મસ્તીનો દોર ફક્ત બપોર સુધી જ ચાલે છે: જેમકે, યુ.કે., ઓસ્ટ્રેલિયા, ન્યૂઝીલેન્ડ અને કેનેડા, જો કોઇ બપોર પછી આવી રમૂજ કરે તો તેનેજ "એપ્રિલ ફૂલ" કહેવામાં આવે છે. પરંતુ બીજા દેશોમાં અને આપણા ભારતમાં પણ, આવી મજાક આખો દિવસ ચાલે છે.
ઉદ્ગ્મ

એપ્રિલ્ફુલ્સ ડેનું ઉદ્ગ્મ ઘણું વિચિત્ર છે. એક વાયકા પ્ર્માણે ગ્રેગેરિયન કેલેન્ડરને અપનાવાયા પછી તુરંત માં આ દિવસ મનાવવાની શરુઆત થઈ.આ શબ્દનો ઉલ્લેખ અમુક કોઐક વ્યક્તિઓ જે હજી પણ જ્યુલિયન કેલેન્ડર વાપરતા હતાં તેમના સંદર્ભમાં થયો હોય. In many pre-Christian cultures May Day (May 1) was celebrated as the first day of summer, and signalled the start of the spring planting season. An April Fool was someone who did this prematurely. 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.
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.
A possible reference to April Fools' Day can be seen in the Canterbury Tales (ca 1400) in the Nun's Priest's tale, a tale of two fools: Chanticleer and the fox, which took place on March 32nd.

* Alabama Changes the Value of Pi: The April 1998 newsletter of New Mexicans for Science and Reason contained an article written by physicist Mark Boslough claiming that the Alabama Legislature had voted to change the value of the mathematical constant pi to the "Biblical value" of 3.0. This claim originally appeared as a news story in the 1961 science fiction novel Stranger in a Strange Land by Robert A. Heinlein.
* Spaghetti trees: The BBC television programme Panorama ran a famous hoax in 1957, showing the Swiss harvesting spaghetti from trees. They had claimed that the despised pest, the spaghetti weevil, had been eradicated. A large number of people contacted the BBC wanting to know how to cultivate their own spaghetti trees. It was, in fact, filmed in St Albans.
* Left Handed Whoppers: In 1998, Burger King ran an ad in USA Today, saying that people could get a Whopper for left-handed people whose condiments were designed to drip out of the right side. Not only did customers order the new burgers, but some specifically requested the "old", right-handed burger.
* Taco Liberty Bell: In 1996, Taco Bell took out a full-page advertisement in The New York Times announcing that they had purchased the Liberty Bell to "reduce the country's debt" and renamed it the "Taco Liberty Bell." When asked about the sale, White House press secretary Mike McCurry replied tongue-in-cheek that the Lincoln Memorial had also been sold and would henceforth be known as the Lincoln Mercury Memorial.
* San Serriffe: The Guardian printed a supplement in 1977 praising this fictional resort, its two main islands (Upper Caisse and Lower Caisse), its capital (Bodoni), and its leader (General Pica). Intrigued readers were later disappointed to learn that San Serriffe (sans serif) did not exist except as references to typeface terminology. (This comes from a Jorge Luis Borges story.)
* Metric time: Repeated several times in various countries, this hoax involves claiming that the time system will be changed to one in which units of time are based on powers of 10.
* Smell-o-vision: In 1965, the BBC purported to conduct a trial of a new technology allowing the transmission of odor over the airwaves to all viewers. Many viewers reportedly contacted the BBC to report the trial's success. In 2007, the BBC website repeated an online version of the hoax.
* Tower of Pisa: The Dutch television news reported once in the 1950s that the Tower of Pisa had fallen over. Many shocked people contacted the station.
* Write Only Memory: Signetics advertised Write Only Memory IC databooks in 1972 through the late 1970s.
* The Canadian news site bourque.org announced in 2002 that Finance Minister Paul Martin had resigned "in order to breed prize Charolais cattle and handsome Fawn Runner ducks."
* Annual BMW Innovations see a new "cutting-edge invention" by BMW advertised across British newspapers every year, examples including:
** Warning against counterfeit BMWs: the blue and white parts of the logo were reversed
** The "Toot and Calm Horn" (after Tutankhamun), which calms rather than aggravates other drivers, so reducing the risk of road rage,
** MINI cars being used in upcoming space missions to Mars,
** IDS ("Insect Deflector Screen") Technology - using elastic solutions to bounce insects off the windscreen as you drive,
** SHEF ("Satellite Hypersensitive Electromagnetic Foodration") Technology , which sees the car's GPS systems synchronise with home appliances to perfectly cook a meal for the instant you return home,
** Marque-Wiper - mini-wipers for each exterior "BMW" logo coming as standard on all future models,
** "Uninventing the wheel" to counter the "EU ban" on right-hand drive cars,
** Zoom Impression Pixels ("ZIP") to counter new "Slow Cameras"
** "BMW Instant Messaging" - using Reactive User Sound Electronic (RUSE) particles to display the driver's words to the car in front on the windscreen.
** A compact disc available to all BMW owners, which when played over the audio system performed minor service and diagnostic checks; when flipped over it played soothing classical music (Australia).
** Canine Repellent Alloy Protection (CRAP)- a means of discouraging dogs from urinating on car wheels. (2008)

In 2007, many users received "Regional moderator" icons with the promise that they would be able to "wield their awesome power" over other users. For April Fools' Day 2008, NationStates has created a new "World Assembly" in the place of the United Nations, as they had received a cease and desist notice from the United Nations for using its name without consent.

વિશ્વમાં આવા અન્ય દિવસો

Iranians play jokes on each other on the 13th day of the Persian new year (Norouz), which falls on April 1 or April 2. This day, celebrated as far back as 536 BC, is called Sizdah Bedar and is the oldest prank-tradition in the world still alive today; this fact has led many to believe that April Fools' Day has its origins in this tradition.

The April 1 tradition in France and French-speaking Canada includes poisson d'avril (literally "April's fish"), attempting to attach a paper fish to the victim's back without being noticed. This is also widespread in other nations, such as Italy (where the term Pesce d'aprile (literally "April's fish") is also used to refer to any jokes done during the day). In Spanish-speaking countries, similar pranks are practiced on December 28, día de los Santos Inocentes, the "Day of the Holy Innocents". This custom also exists in certain areas of Belgium, including the province of Antwerp. The Flemish tradition is for children to lock out their parents or teachers, only letting them in if they promise to bring treats the same evening or the next day.

In Poland, prima aprilis ("April 1" in Latin) is a day full of jokes; various hoaxes are prepared by people, media (which sometimes cooperate to make the "information" more credible) and even public institutions. Serious activities are usually avoided. This conviction is so strong that the anti-Turkish alliance with Leopold I signed on April 1, 1683, was backdated to March 31.

In Scotland, April Fools' Day is traditionally called Hunt-the-Gowk Day ("gowk" is Scots for a cuckoo or a foolish person), although this name has fallen into disuse. The traditional prank is to ask someone to deliver a sealed message requesting 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 he can only help if he first contacts another person, and sends the victim to this person with an identical message, with the same result. Also Scotland has 2 whole days for pranks, April 1 and April 2.

In Denmark the 1st of May is known as "Maj-kat", meaning "May-cat", and is identical to April Fools' Day, though Danes also celebrate April Fools' Day ("aprilsnar").

Some Jewish communities have a traditional event called a Purim spiel, which is similar in many ways to April Fools' Day. Fake newspaper articles are common.
