Hispanic Heritage Month is observed from September 15 to October 15 every year to celebrate the positive impact and contributions of Hispanic and Latinx Americans to the nation.
Initially established as a week-long observance by President Lyndon B. Johnson in 1968, it was later expanded into a month-long celebration by President Ronald Reagan in 1988, which was enacted into law later that year.
September is of particular significance because it is the month of independence for several Latin American countries, including Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, Mexico, and Chile. This unusual mid-month beginning and ending of the observance was chosen to coincide with these independence days. The month is also commonly known as Latino Heritage Month or Latinx Heritage Month, which includes celebrating Brazilian culture.
