May 5, otherwise known as Cinco De Mayo throughout Mexico and the United States, as well as other parts of the world.
Cinco de Mayo is not a current Mexican holiday, although at one point in history, it had been declared a national holiday in 1862 by Mexican President Benito Juárez. Contrary to popular opinion, Cinco de Mayo is not a holiday celebrating Mexican Independence. It is a day that celebrates the Mexican army’s victory over France in the battle of Puebla on May 5, 1862. France had the mightier military force and was expected to easily win the battle. Instead, the Mexican army of only 4,000 strong was victorious over the French who had an army of 8,000 in the Franco-Mexican War
