What time zone is Durango in?
Mountain. Colorado law sets the state's standard clock as Mountain Standard Time, seven hours behind UTC. Summer is the other half. Clocks jump one hour ahead at 2 AM on the second Sunday of March and fall back at 2 AM on the first Sunday of November, per Colorado Revised Statutes 2-4-109. That makes Durango a UTC-6 town for about eight months of every year.
Nothing local bends the answer. The whole county follows Denver, and so do the airport, the courthouse and the ski area, so a train timetable printed in Silverton and a lift schedule printed at Purgatory run on the same clock as your phone.
When do the clocks change in Durango?
For 2026, the switch back happens at 2 AM on Sunday, November 1, according to NIST. Two o'clock becomes one o'clock, and that hour happens twice. The next spring-forward falls on the second Sunday of March 2027, which is March 14.
Here is what it does to a Durango evening. We pulled downtown sunrise and sunset times from the U.S. Naval Observatory for the days around the change, plus the two extremes of the year.
| Date | Sunrise | Sunset |
|---|---|---|
| Oct. 31, 2026 | 7:35 AM | 6:15 PM |
| Nov. 1, 2026 | 7:36 AM | 6:13 PM |
| Nov. 2, 2026 | 6:37 AM | 5:12 PM |
| Dec. 21, 2026 | 7:22 AM | 4:58 PM |
| June 21, 2027 | 5:51 AM | 8:35 PM |
Read the jump between Sunday and Monday. Dusk arrives a full hour earlier by the wall clock, from 6:13 to 5:12, even though the sun itself slipped about a minute. Sunrise leaps the other way, from 7:36 to 6:37, so Monday morning is bright before most people leave for work.
Midwinter gives Durango roughly 9 hours and 36 minutes of sun. Midsummer stretches past 14. Pick your trail runs and ski days with those numbers in mind, and if you need ideas for where locals head after work, our parks and trails guide has them.
The shift also lands just ahead of snow season. Purgatory Resort lists Friday, November 20 as its scheduled opening day, per its lift ticket page.
Could Colorado stay on summer hours all year?
On paper, yes, but not yet. A later clause in that same law would make the summer clock permanent, but only after two things happen. Congress has to pass a bill that lets states do it, and at least four other Mountain-zone states must enact the same change. Until the governor tells the revisor of statutes that both conditions are met, the clause sits idle (C.R.S. 2-4-109).
The statute's own name for that permanent clock is "United States Mountain Daylight Saving Time," or UTC minus six hours. NIST still publishes the standard March-to-November calendar for 2026, and we found nothing suggesting the conditions have been met, so expect the usual change on November 1.
How does Durango's time compare with nearby places?
New Mexico, 20 miles south, moves its clocks on identical dates, since NIST names only Arizona and a few territories as exceptions. Arizona is the one that matters here, because the Four Corners sits just 84 miles away, per the Durango Area Tourism Office. NIST notes that most Arizonans skip the change, though the Navajo Nation observes it.
In practice, the clock on a drive toward Phoenix depends on the season and on whose land you are crossing. From November to March, Arizona matches Colorado. For the rest of the year most of that state runs an hour behind, while Navajo land stays in step with Durango. Scheduling a call with someone in Arizona? Ask where in Arizona.
Heading east is easier. Denver shares Durango's time, which keeps the 6.5-hour trip simple. We cover that route in how far Durango is from Denver.
