Hispanic Heritage Month celebrates the culture and contributions of Americans tracing their roots to Spain, Mexico, Central America, South America and the Spanish-speaking nations of the Caribbean. The observance was born in 1968 when Congress authorized the president to issue an annual proclamation designating National Hispanic Heritage Week. Two decades later, lawmakers expanded it to a monthlong celebration, stretching from September 15 to October 15.
Hispanic Heritage Month — like its shorter precursor — always starts on September 15, a historically significant day marking the independence of five Latin American countries: Costa Rica, El Salvador, Guatemala, Honduras and Nicaragua. The designated period is also a nod to those from Mexico and Chile, which celebrate their independence September 16 and September 18, respectively.
