The national holiday of each country that celebrates that country's nationhood. Each country has a single national day, as a single nation cannot be formed on two separate dates; for example, the United States of America celebrates their national day on Independence Day (United States). Days like National Catfish Day, while called national days, are not officially designated, and do not celebrate nationhood. Such days are categorized under Category:Observances and its subcategories.
