Many countries in the New World and elsewhere celebrate the anniversary of Christopher Columbus's arrival in the Americas, which occurred on October 12, 1492 in the Julian calendar and October 21, 1492 in the modern Gregorian calendar, as an official holiday. The day is celebrated as Columbus Day in the United States, as Día de la Raza (Day of the (Hispanic) race) in many countries in the Americas, as Día de las Culturas (Day of the Cultures) in Costa Rica, as Discovery Day in the Bahamas, as Día de la Hispanidad and Fiesta Nacional in Spain, as Día de las Américas (Day of the Americas) in Uruguay and as Día de la Resistencia Indígena (Day of Indigenous Resistance) in Venezuela. These holidays have been celebrated unofficially since the late 18th century, and officially in various countries since the early 20th century.
