Indigenous Peoples’ Day Act

This bill replaces "Columbus Day" with "Indigenous Peoples’ Day" as the official federal holiday observed on the second Monday in October. It directly affects federal government operations and all federal documents, rules, or laws that previously referenced "Columbus Day" by automatically updating those references to "Indigenous Peoples’ Day" upon enactment. The key mechanism is a simple amendment to federal law (5 U.S.C. § 6103(a)) to change the holiday name and a provision ensuring all existing federal references to Columbus Day are legally treated as referring to Indigenous Peoples’ Day instead. This is a procedural change to federal holidays and references, not a new policy or program.
