National Colorado Day is observed every August 1 to commemorate Colorado's admission to the Union as the 38th state in 1876. This day, also known as Colorado Day, is marked by various events and activities at the Colorado State Capitol, including speeches, concerts, historical presentations, exhibitions, and family-friendly games. The celebration highlights Colorado's rich history, which includes the presence of Native American tribes for over 13,000 years and the arrival of European settlers in the 18th century. Although not a state holiday, Colorado Day serves as an opportunity for residents and visitors to engage in local festivities that honor the state's heritage. An alternative celebration, National Colorado Day, is held on April 12, initiated by National Day Calendar in 2017.
