Bastille Day
The French National Day is the anniversary of Storming of the Bastille on 14 July 1789, a turning point of the French Revolution, as well as the Fête de la Fédération which celebrated the unity of the French people on 14 July 1790. Celebrations are held throughout France. The oldest and largest regular military parade in Europe is held on the morning of 14 July, on the Champs-Élysées in Paris in front of the President of the Republic, along with other French officials and foreign guests.
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.
