About this calendar

Colorado Holidays lists the public observances tracked across Colorado and the wider United States federal holidays schedule, including dates recognized by the federal government and commonly observed by businesses, banks, schools, and public offices. The framework follows the federal holiday system administered through the Office of Personnel Management and related U.S. government guidance, with fixed-date holidays and Monday observances when a holiday falls on a weekend. In practice, the calendar centres on the recurring national holiday pattern rather than state-only commemorations, which makes it useful for planning across Colorado's work, school, and civic timetable. Entries cover a mix of federal holidays and widely watched observances that shape the start of the year and the spring calendar, including New Year's Day, Martin Luther King Jr. Day, Washington-Lincoln Day, Easter Sunday, Tax Day, and Administrative Professionals Day. The holiday sequence typically begins in January and continues through the year as federal observances arrive in regular intervals, with some dates fixed and others linked to a weekday pattern or religious calendar. Colorado employers, educators, public sector offices, and households often use these holidays to plan office closures, payroll timing, travel, and event scheduling. Because the list is centered on Colorado and the U.S. calendar, it also helps with coordination across state lines when local operations follow federal timing. Subscribers can add Colorado Holidays as a Smart Calendar Feed, free to subscribe, and keep the observance list in Apple Calendar, Google Calendar, or Outlook without manual entry. That is useful for administrators, finance teams, school offices, and anyone coordinating meetings around federal closures or shortened business weeks. The holiday calendar is especially practical when personal reminders, school terms, and business deadlines need to stay aligned with public observance days in Colorado and the broader United States. The calendar updates regularly so cancellations, rescheduled observances, and calendar changes appear automatically in the connected app. That matters most when a holiday-related office closure is announced late or when a weekday observation shifts due to the federal rules that govern holiday placement.
