"Cinco de Mayo, or the fifth of May, is a holiday that celebrates the date of the Mexican army’s May 5, 1862 victory over France at the Battle of Puebla during the Franco-Mexican War. The day, which falls on Wednesday, May 5 in 2021, is also known as Battle of Puebla Day. While it is a relatively minor holiday in Mexico, in the United States, Cinco de Mayo has evolved into a commemoration of Mexican culture and heritage, particularly in areas with large Mexican-American populations."

"Many people outside Mexico mistakenly believe that Cinco de Mayo is a celebration of Mexican independence, which was declared more than 50 years before the Battle of Puebla."

"Independence Day in Mexico (Día de la Independencia) is commemorated on September 16, the anniversary of the revolutionary priest Miguel Hidalgo y Costilla’s famous “Grito de Dolores” (“Cry of Dolores,” referring to the city of Dolores Hidalgo, Mexico), a call to arms that amounted to a declaration of war against the Spanish colonial government in 1810."
