Hispanic Heritage Month is celebrated annually from September 15 to October 15 in the United States. This month-long observance recognizes the contributions and influence of Hispanic culture to the nation's history, culture, and achievements. The starting date, September 15, was chosen because it marks the independence anniversaries of several Latin American countries, including Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua. Additionally, Mexico and Chile celebrate their independence days on September 16 and September 18, respectively. The month also includes the celebration of Columbus Day or Día de la Raza on October 12, which honors the fusion of indigenous and European heritage in Spanish-speaking countries.
