April Fools' Day or April Fool's Day

Teasers picture: It looks as if one of Copenhagen's metro cars had an accident, and had broken through and surfaced on the square in front of the town hall. In reality, it was a retired subway car from the subway of Stockholm cut obliquely, with the front end placed onto the tiling and loose tiles scattered around it. Note the sign "Gevalia" and the accident site tape with the words "Uventede gæster?" (unexpected guests?). Gevalia coffee's advertising featured various vehicles popping up with unexpected guests.

There is uncertainty as to where the custom originated, but one theory is that its origin must be found in France when the Julian calendar was replaced by the Gregorian in 1582 and moved New Year's Day from March 25 to January 1.

April's old calendar tradition.
Those who continued to keep the old calendar tradition alive and celebrated the end of New Year's week April 1 were therefore called April Fools, or like they do in Italy, France, Belgium and French-speaking areas of Switzerland and Canada, April 1 tradition is often known as "April fish" (poissons d'avril in French. this happened in France 1508 and the use of January 1 as New Year's Day became common in France only by the mid-16th century, and the date was not adopted officially until 1564.

Since about 1900, many newspapers and other media have had a tradition of bringing in an untrue story on April 1st. Today, April fool are increasingly happening on the Internet.

 

Instant Color TV from the Swedish TV SVT April 1962
Sweden's SVT (Sveriges Television) brought their technical expert, Kjell Stensson, onto the news to inform the public that, thanks to a new technology, viewers could convert their existing sets to display color reception. At the time, there was only the one TV channel in Sweden, and it broadcast in black and white, so this was big news. Stensson explained that all viewers had to do was pull a nylon stocking over their tv screen, and the mesh would cause the light to bend in such a way that it would appear as if the image was in color. He proceeded to demonstrate the process. Thousands of people were taken in. Many Swedes today still report remembering their fathers rushing through the house trying to find stockings to place over the TV set. Regular color broadcasts only commenced in Sweden on April 1, 1970.
