Today is the 131st anniversary of our state. President Ulysses S. Grant signed the proclamation admitting Colorado into the United States on August 1, 1876. To celebrate, the Colorado History Museum will have free admission today, and there will be a celebration at the Capitol from 10am – 6pm. While many people celebrate Colorado Day on August 1st, the official holiday according to Colorado statutes is actually the first Monday in August (CRS 24-11-111). In years past Colorado Day was a holiday for state employees, and in 1967 the state legislature changed Colorado Day to the first Monday in August, creating a three day holiday. In 1986 the state began observing Martin Luther King day as an official state holiday in lieu of Colorado Day. Colorado State Parks will celebrate Colorado Day by waiving admission fees at all 41 parks on Monday, Aug. 6.
