Denver lies at 105.0° west, where mean solar time is UTC−7 (four minutes per degree of longitude). That is within 1 min of its standard time, so the sun is highest close to noon in winter, and about 1:00 PM in summer.
Daylight saving time in Colorado
Yes. Colorado moves its clocks forward one hour on the second Sunday of March at 2:00 AM and back on the first Sunday of November at 2:00 AM (local time).
These are the federal dates (15 U.S.C. §260a); the daylight saving time page has the law.
All coming change dates are on the America/Denver page.
Clock history of Colorado
Colorado has kept the same clocks as Denver since at least 1970: tzdata records both under America/Denver. Clocks have moved for daylight saving time every year since 1970. Before 1970 local practice could differ from Denver’s, and tzdata does not track it separately; the year-by-year table, which starts with Denver’s local mean time, is on the America/Denver page.
