Friend's Day is a celebration of friendship held annually on July 20th, mainly in Argentina and Uruguay but also in some other countries.
The idea for Friend's Day goes back to Argentine teacher, musician, and dentist Enrique Febbraro, who had the idea of turning the anniversary of the first moon landing into an international day of friendship. He argued that on this particular day, the whole world had been friends of the three astronauts. The first official recognition of the day came with decree No. 235/79 by the government of the province of Buenos Aires, which authorized the celebration and gave it official nature.
In Argentina, Friend's Day is often a good excuse for a common friendly gathering, though people also employ the day to get in contact with old and seldom-met friends and greet them. Since it is not a public holiday in Argentina, the gatherings tend to happen during the evening.
Though Friend's Day has always been respected, in recent years it has turned into a very popular mass phenomenon. In 2005, too many well-wishing friends led to a temporary breakdown of the mobile phone network in the cities of Buenos Aires, Córdoba and Rosario. In Rosario, the celebration of the Friends Day has been moved to the 19th of July, when Roberto Fontanarrosa, the best comic writer of the city, died.
