There are several holidays and observances on October 9, but the main ones are Columbus Day and Indigenous Peoples Day. Columbus Day is a federal holiday in the United States that commemorates the arrival of Christopher Columbus in the Americas in 1492. Indigenous Peoples Day is a counter-celebration that honors and celebrates the Native American people and their history. Government offices, banks, and the U.S. Postal Service are closed on Columbus Day. However, some schools and libraries may be open or closed depending on the location.
