Each year, Americans observe National Hispanic Heritage Month from September 15 to October 15, by celebrating the histories, cultures, and contributions of those whose ancestors came from Spain, Mexico, the Caribbean and Central and South America.
The observation started in 1968 as Hispanic Heritage Week under President Lyndon Johnson and was expanded by President Ronald Reagan in 1988 to cover a 30-day period starting on September 15 and ending on October 15. It was enacted into law on August 17, 1988.
The day of September 15 is significant because it is the anniversary of independence for Latin American countries Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua. In addition, Mexico and Chile celebrate their independence days on September 16 and September 18, respectively.
Lastly, through a 2014 Presidential Proclamation under President Barack Obama, National Hispanic Serving Institutions Week is September 14-20. Within the 30-day period of Hispanic Heritage Month, Día de la Raza is observed on October 12.
