September 16 is officially Mexican Independence Day. The day is called "Grito de Dolores" (literally Shout from Dolores) or their Independence from Spain, and is routinely celebrated in Mexico.
Many Mexican-Americans and Mexicans living in the US pay little heed to that occasion, but do celebrate "Cinco de Mayo" (fifth of May) as a patriotic holiday. On May 5, 1862, Mexican forces defeated an invading French army at the Battle of Puebla.
