The Mountain Time Zone is the time zone used by Denver, Colorado, and 10 other states within the United States. Mountain Time is seven hours behind Coordinated Universal Time (UTC-7). It’s essential to be aware of the time difference when traveling to or communicating with Denver.

To make sure you adjust to the time zone smoothly, we suggest avoiding caffeine and alcohol on the day of travel, getting plenty of rest the night before, and setting your watch to Mountain Time as soon as you board your flight. Also, try to adjust your eating and sleep schedule to match the local time as soon as you can.

Avoiding common mistakes, such as booking flights on the wrong day or missing important meetings due to incorrect time zone calculations, is crucial to ensuring a positive travel experience.

What Time is it in Denver? Understanding Mountain Time

Mountain Time is defined as a time zone that is seven hours behind Coordinated Universal Time (UTC-7). It’s used primarily in the Western United States, including Denver, Colorado.

Compared to Eastern Standard Time, which is five hours behind UTC, and Pacific Standard Time, which is eight hours behind, Denver sits comfortably in the middle.

Additionally, Denver observes Daylight Saving Time and moves its clocks forward by one hour on the second Sunday in March and back by one hour on the first Sunday in November.

Why Denver is on Mountain Time: A Historical Perspective

Denver’s time zone history can be traced back to the late 1800s, a time when time zones were not standardized, and railroad companies primarily determined local time. Before the establishment of Mountain Standard Time, Denver kept time that was only 28 minutes behind Eastern Standard Time.

The adoption of Mountain Time was primarily motivated by the need to improve timekeeping accuracy and efficiency for rail transportation. Denver was a critical transportation hub, with several railway lines intersecting in the city. Standardizing the time zone helped to streamline travel schedules and reduce confusion for travelers and rail operators alike.

Compared to other cities on the Mountain Time Zone, Denver’s location centered around the Rockies also played a role in its designation as Mountain Time.

Denver’s Time Zone: How it Affects the City’s Businesses and Residents

Being on Mountain Time has significant implications for businesses and residents in Denver. For example, it means that the city’s residents may need to adjust to earlier or later work hours compared to others in the same time zone. In addition, Denver may have to start or end business hours earlier to align with customers or clients in different time zones.

On the other hand, Mountain Time’s location, shared with several other scenic destinations in the United States, makes it a popular location for tourists and businesses. It also allows for easy communication with both coastal regions in the United States with just a three-hour time difference.

Denver’s Time Zone: Tips for Adjusting to Mountain Time from East or West Coast

Adjusting to a new time zone can be challenging, but there are several tips that can help make it easier. For example, get plenty of sunlight during the day, avoid screens at least an hour before bed, and stay hydrated.

If you’re coming from the East Coast, try to stay up as late as possible on your first night in Denver to help adjust to the new time zone. Conversely, if you’re coming from the West Coast, try to go to bed earlier and wake up earlier to get onto Mountain Time. Lastly, avoid consuming too much alcohol or caffeine, as these can disrupt your sleep patterns and make it harder to acclimate to the time zone.


Understanding Denver’s time zone is crucial for a successful trip to the city, whether for business or pleasure. Being on Mountain Time allows access to both East and West Coast cities and scenic destinations, but it also requires travelers to account for the time difference when planning their schedules. By following our tips for adjusting to Mountain Time and avoiding common mistakes, you can enjoy your time in Denver to the fullest.
