National Hispanic Heritage Month is celebrated in the United States annually from September 15 to October 15. This month-long observance recognizes the contributions and influence of Hispanic culture on the nation's achievements, culture, and history. The celebration starts on September 15 because it marks the anniversary of independence for several Latin American countries, including Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua. Mexico's independence is celebrated on September 16, and Chile's on September 18. The observance also includes Columbus Day or Día de la Raza, which falls on October 12. This month-long period was expanded from a week-long celebration in 1968 to its current form in 1988, formalized by legislation signed into law in the U.S.
