Is on the second Monday of October, remembers Christopher Columbus’ arrival to the Americas on October 12, 1492
Columbus Day first became an official state holiday in Colorado in 1906, and became a federal holiday in the United States in 1937, though people have celebrated Columbus’s 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 citizenship boundaries, the importance of loyalty to the nation, and celebrating social progress.
Since 1970 (Oct. 12), the holiday has been fixed to the second Monday in October, coincidentally exactly the same day as Thanksgiving in neighboring Canada fixed since 1959. It is generally observed nowadays by banks, the bond market, the U.S. Postal Service, other federal agencies, most state government offices, many businesses, and most school districts.
