Independence Day (Niger)
The date of the formal, complete independence from France was 3 August 1960, while 18 December 1958 marks the founding of the Republic and creation of the Presidency of the Republic of Niger, following the constitutional changes of the French Fifth Republic, and the elections of 4 December 1958 held across The French Colonial possessions. Nigeriens consider that date to be the founding of their national institutions. Between 18 December 1958 and 3 August 1960, Niger remained a semi-autonomous Republic within the French Community. At the beginning of 1960 a revision of the French Community allowed membership of independent states, and on 28 July the Nigerien Legislative Assembly became the Nigerien National Assembly: Independence was declared on 3 August 1960.
April Fools' Day
In 1508, French poet Eloy d'Amerval referred to a "poisson d’avril" (April fool, literally "Fish of April"), possibly the first reference to the celebration in France. Some writers suggest that April Fools' originated because in the Middle Ages, New Year's Day was celebrated on March 25 in most European towns, through a holiday that in some areas of France, specifically, ended on April 1, and those who celebrated New Year's Eve on January 1 made fun of those who celebrated on other dates by the invention of April Fools' Day. 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, thanks to the Edict of Roussillon.
