Hispanic Heritage Month is celebrated annually from September 15 to October 15 in the United States. This month-long observance recognizes and honors the contributions and influence of Hispanic culture to the nation's history, achievements, and culture. The starting date, September 15, is significant as it marks the anniversary of independence for several Latin American countries including Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua. Other important independence days during this period include Mexico on September 16 and Chile on September 18.
