CO HB1185

Establishes Colorado Day as a new state legal holiday to be observed on the first Monday in August, replacing Columbus Day as a recognized state holiday.

Removes Columbus Day (second Monday in October) from the list of state legal holidays in Colorado Revised Statutes 24-11-101.

Updates the definition of "business day" in Colorado statutes 5-1-301 and 6-1-102 to include Colorado Day and exclude Columbus Day for purposes of financial instruments and court proceedings.

Includes legislative findings stating that state holidays honor prominent historical figures and civic events, and that replacing Columbus Day does not diminish recognition of Italian-American contributions to the state.

Takes effect August 2, 2019, unless a referendum petition is filed, in which case the measure requires voter approval at the November 2020 general election.
