Columbus Day is observed annually on the second Monday of October. The first official federal observation of Columbus Day occurred in 1937. In 1972, New York was the first state to celebrate Columbus Day, 300 years after Christopher Columbus declared that he had discovered America.
Columbus Day is considered a loosely observed federal holiday, meaning many businesses and establishments remain open and keep regular hours. Banks, federal offices and state offices observe Columbus Day and resume normal hours on the Tuesday following the holiday.Learn more about Postal Services
