Mountain Time between the coasts
Colorado lies entirely within the Mountain Time Zone, which stretches from Montana and Idaho down to New Mexico and the western tip of Texas. Denver is the zone's best-known reference city. It sits two hours behind New York and one hour ahead of Los Angeles all year, because all three switch on the same Sundays.
The neighbor that complicates things is Arizona. Phoenix stays on MST without daylight saving, so it matches Denver from November to March and falls one hour behind from March to November. Utah, New Mexico and Wyoming change clocks with Colorado. Teams that span the Rockies should check the season before booking a cross-state call.
A mile high and close to the 105th meridian
Denver sits almost exactly on 105° west, the meridian Mountain Standard Time is based on, so solar noon falls within about 15 minutes of 12:00 in winter and near 1:00 PM in summer. Around the June solstice the sun rises near 5:32 AM and sets about 8:31 PM, roughly 15 hours of light. In December sunrise is around 7:18 AM and sunset around 4:38 PM, a day of about 9 hours 20 minutes.

Denver's workday against the rest of the country
The New York Stock Exchange opens at 7:30 AM in Denver and closes at 2:00 PM. That central position is useful for national teams: 10:00 AM in Denver is noon in New York and 9:00 AM in Los Angeles, a slot where all three coasts are at work. London is seven hours ahead for most of the year. The MST to EST page has the full hour-by-hour table, and the world clock shows Denver next to other cities.
Frequently asked questions
- Is Denver two hours behind New York?
- Yes, year-round. Colorado and New York change clocks on the same Sundays, so the difference never changes.
- Does Colorado observe daylight saving time?
- Yes. Colorado switches to MDT on the second Sunday of March and back to MST on the first Sunday of November, like most of the country.
- What time is it in Denver when it is noon in London?
- 5:00 AM for most of the year. During the few weeks when the US and UK clock changes are out of step, it is 6:00 AM.
- Is Mountain Time the same as Denver time?
- Denver is the reference city for Mountain Time, and calendar apps often list the zone as 'America/Denver'. The exception within the zone is most of Arizona, which skips daylight saving.

- About 15 hours around June 20, with sunrise close to 5:30 AM and sunset after 8:30 PM.
