Each column is one day from sunrise to sunset in local clock time. The one-hour steps are the daylight saving time changes.

The longest day in 2026 is June 21 with 14 h 59 min between sunrise at 5:32 AM and sunset at 8:31 PM. The shortest is December 21 with 9 h 21 min. The difference, 5 h 38 min between June 21 and December 21, ranks 27th largest among the 51 capitals. That is typical for a capital at this latitude.

Earliest sunrise and latest sunset

The earliest sunrise of the year comes on June 8 at 5:31 AM, and the latest sunset on June 25 at 8:32 PM. The latest sunrise falls on October 31 at 7:27 AM, and the earliest sunset on December 1 at 4:35 PM.

Clocks change on March 8 (to MDT) and November 1 (to MST), which moves every clock time by an hour. The earliest sunrise and latest sunset still fall days away from the longest day, because solar noon drifts through the year.

Solar noon and the time zone

On standard time Denver's clocks run 7 hours behind UTC, which matches the meridian at 105° W. The capitol sits at 104.99° W, almost exactly on that meridian, so the clock and the sun agree closely on standard time. Solar noon on January 15 is at 12:09 PM and on July 15 at 1:06 PM; the rest of the gap comes from daylight saving time and the equation of time.

Compared with neighboring capitals

Day length depends on latitude, so capitals to the north get longer June days and shorter December days. Among neighbors, Cheyenne gets the most June daylight, 9 minutes more than Denver on June 21.
