September 15 – October 15 is officially Hispanic Heritage Month in the United States. This is a time to recognize American citizens with Latino ancestry and celebrate the vital contributions that the Hispanic culture weaves into our American fabric.
First proclaimed by President Lyndon Johnson in 1968 as Hispanic Heritage Week, it was extended to a month-long recognition under President Ronald Reagan in 1988. Originally established to honor neighboring Central American countries who celebrate independence in September (Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua and Mexico), it has since become a lively and colorful month to celebrate Hispanic cultures and customs.
