Each year, Americans observe National Hispanic Heritage Month from September 15 to October 15, by celebrating the histories, cultures and contributions of American citizens whose ancestors came from Spain, Mexico, the Caribbean, 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. It was enacted into law on August 17, 1988.  To learn more visit National Hispanic Heritage Month.
