October 13, 2025, is Columbus Day in the United States, a federal holiday celebrated on the second Monday of October. It commemorates Christopher Columbus's historic voyage and is observed with various ceremonies and activities. On the same day, Indigenous Peoples' Day is also recognized in many places, reflecting a movement to honor the history and culture of Native Americans as a counterpoint to Columbus Day. Banks and federal offices are generally closed on this day, but stock markets remain open. Additionally, October 13 is the anniversary of the U.S. Navy's founding.

In Spain, although October 12 (Día de la Hispanidad) falls on a Sunday in 2025, only some regions observe a day off on Monday, October 13.
