Native American Day is a state holiday in California, established in 1968 to honor Native American cultures and contributions to the state and the United States. Also called American Indian Day, it is observed annually on the fourth Friday in September.

In 1968, Governor Ronald Reagan signed a resolution calling for a holiday called American Indian Day, to be held the Fourth Friday in September. In 1998, the California Assembly passed AB 1953, which made Native American Day an official state holiday.

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, as an official holiday. The event is celebrated as Columbus Day in the United States, as Día de la Raza in many countries in Latin America, as Discovery Day in the Bahamas, as Día de la Hispanidad, Fiesta Nacional in Spain, Día del Respeto a la Diversidad Cultural (Day of Respect for Cultural Diversity) in Argentina and as Día de las Américas (Day of the Americas) in Uruguay. These holidays have been celebrated unofficially since the late 18th century, and officially in various areas since the early 20th century.

Columbus Day first became an official state holiday in Colorado in 1906, and became a federal holiday in 1937, though people have celebrated Columbus' voyage since the colonial period. In 1792, New York City and other U.S. cities celebrated the 300th anniversary of his landing in the New World. President Benjamin Harrison called upon the people of the United States to celebrate Columbus Day on the 400th anniversary of the event. During the four hundredth anniversary in 1892, teachers, preachers, poets and politicians used Columbus Day rituals to teach ideals of patriotism. These patriotic rituals were framed around themes such as support for war, citizenship boundaries, the importance of loyalty to the nation, and celebrating social progress.^[1][2]
