What is the date of National Nacho Day in the United States?

National Nacho Day in the United States is observed on November 6. The food holiday celebrates nachos, the tortilla-chip-and-melted-cheese dish associated with Mexican restaurateur Ignacio “Nacho” Anaya.

Nachos originated in 1943 in Piedras Negras, Coahuila, Mexico, just across the border from Eagle Pass, Texas. Anaya created the snack at the Victory Club after a group of American military officers’ wives arrived and the usual cook was unavailable. His quick combination of fried tortilla pieces, cheese, and jalapeño peppers became known as “Nacho’s Special.”

November 6 is a U.S. observance rather than the anniversary of the dish’s creation. That distinction explains why the date does not match 1943 or a documented birthday of Anaya. It is also separate from the International Day of the Nacho, associated with October 21 in Piedras Negras. Because food holidays are often promoted by calendars, restaurants, and media rather than established as federal holidays, National Nacho Day is best understood as a popular annual observance, not a legal public holiday.
