Today is the first day of U.S. National Hispanic Heritage Month which is marked by celebrating the histories, cultures, and contributions of American citizens 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 September18, respectively. Also, Columbus Day or Día de la Raza, which is October 12, falls within this 30 day period.
