September 15 through October 15, the United States of America celebrates Hispanic Heritage Month. Americans celebrate the culture and traditions of those who trace their roots to Mexico, Puerto Rico, Spain, and all the other Spanish-speaking nations of Central America, South America and the Caribbean.
September 15 was chosen for the celebration because it is the anniversary of independence of five Latin American countries: Costa Rica, El Salvador, Guatemala, Honduras and Nicaragua. They all declared independence in 1821. Additionally, Mexico, Chile and Belize celebrate their independence days on September 16, September 18, and September 21, respectively.
