Explorer Christopher Columbus landed in the Americas on Oct 12, 1492.
It was declared a federal holiday in 1937.
The presidential proclamation requires the American flag to be flown on all public buildings.
Because it is a federal holiday, institutions like banks and post offices will be closed Monday.
Parades are also scheduled across the nation to celebrate Columbus Day, including one of the largest in New York City featuring about 35,000 marchers.
While we’re celebrating Columbus Day, our neighbors to the north are kicking off Thanksgiving.
Canadians traditionally celebrate the holiday the second Monday of October.
It shares several traditions with the U.S. version, including turkey as the main course at big meals shared with family.
