Hispanic Heritage Month in 2025 is from Monday, September 15 to Wednesday, October 15. This month-long celebration honors the history, culture, and contributions of Hispanic and Latino Americans in the United States. The start date, September 15, is significant because it coincides with the independence anniversaries of several Latin American countries including Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua, with Mexico's independence day on September 16 and Chile's on September 18.
