Hispanic Heritage Month is celebrated from September 15 to October 15 in the United States to recognize and honor the contributions and influence of Hispanic culture on the nation's history, achievements, and culture. It originated as Hispanic Heritage Week in 1968, established by legislation signed by President Lyndon B. Johnson, and was expanded to a month in 1988 by President Ronald Reagan. The starting date, September 15, corresponds with the independence anniversaries of several Latin American countries including Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua. The month also includes significant independence days of other Hispanic countries and the celebration of Columbus Day (Día de la Raza). The month highlights the diverse and inclusive environment shaped by Hispanic Americans and educates the broader U.S. public about their history, culture, and contributions to society.
