September 15 marks the first day of Hispanic-Latinx Heritage Month in the United States. The celebration, which is also referred to as National Hispanic Heritage Month, began as Hispanic Heritage week when it was established by legislation that was signed into law by President Lydon Johnson in 1968. In 1988, the single week event was expanded to a month-long period to be celebrated each year from September 15 to October 15.
September 15 is of significance as it marks the anniversary of independence of the Latin American countries of Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua. Mexico also celebrates independence on September 16, Chile on September 18, and Belize on September 21.
