Columbus Day, holiday commemorating Christopher Columbus's discovery of America. It has been traditionally celebrated on Oct. 12 throughout most of the United States, parts of Canada, and in several of the Latin American republics. In the United States, however, since the observation in 1971 of the Uniform Holiday Act, it is celebrated on the Monday nearest to Oct. 12.
Columbus Day first became an official state holiday in Colorado in 1905, and became a federal holiday in 1934. But people have celebrated Columbus' voyage since the colonial period. In 1792, New York City and other eastern U.S. cities celebrated the 300th anniversary of his landing in the New World. In 1892, President Benjamin Harrison called upon the people of the United States to celebrate Columbus Day on the 400th anniversary of the event.
God Bless America!
