Colorado, like most of the western United States, operates on Mountain Time (MT), which is six hours behind Coordinated Universal Time (UTC). This means that when it’s 12:00 PM UTC, it’s 6:00 AM MT in Colorado. But there’s more to it than just the basics. Colorado’s relationship with time has a fascinating history and some unique quirks that make it a bit more complicated than you might think.
The History of Time Zones in Colorado
From Local Sun Time to Standard Time
Before the advent of standard time zones, each town and city followed its own “local sun time,” which was determined by the position of the sun in the sky. This led to significant discrepancies in time across different locations, making it difficult to coordinate schedules and travel. To address this problem, the United States adopted standard time zones in 1883, dividing the country into four time zones: Eastern, Central, Mountain, and Pacific.
Colorado’s Early Time Zones
Prior to 1883, Colorado was divided between two time zones: the 105th meridian time zone, which ran through the western part of the state, and the 109th meridian time zone, which encompassed the eastern portion. However, as the railroad expanded westward and standardized time became increasingly important for transportation, Colorado shifted to a single time zone: Mountain Time.

Daylight Saving Time in Colorado
In 1918, the United States adopted daylight saving time (DST) for the first time, which involved shifting clocks forward by one hour during the summer months to make better use of daylight. This practice has been adopted and repealed several times throughout history, and Colorado has its own unique history with DST.
Colorado’s DST Saga
Colorado initially observed DST, but in 1973, voters approved a referendum that permanently abolished DST in the state, making Colorado one of the few states in the U.S. that did not observe DST. However, in 2005, Congress passed a law that mandated DST for most of the country, forcing Colorado to once again observe DST against the will of its residents. In 2023, most of the country is moving towards a permanent DST, but Colorado still retains the option to permanently stay on Mountain Standard Time. What happens in the future is still uncertain.
The Impact of Time Zones on Colorado Life
The unique time zone and the recurring debate over daylight saving time have had a significant impact on Colorado life. It affects everything from business hours and school schedules to sporting events and social gatherings.
Business and School Schedules
The Mountain Time Zone means that Colorado’s business hours and school schedules are typically one hour ahead of those on the East Coast and two hours ahead of those on the West Coast. This can be challenging for businesses that operate nationwide or internationally, but it also presents opportunities for Colorado businesses to take advantage of overlapping work hours with East Coast and West Coast counterparts.
Sporting Events
Colorado’s time zone plays a significant role in the state’s sports scene. For example, football games involving the Denver Broncos are often broadcast nationally in prime time, but for Colorado fans, these games often start much earlier in the evening. And for fans watching international sporting events, the Mountain Time Zone can mean early morning wake-up calls to catch the action.
How to Find the Current Time in Colorado
With the internet and smartphone apps, it’s easier than ever to find the current time in Colorado. Here are some quick and convenient methods:
Online Time Zone Converters
There are numerous websites and mobile apps that offer time zone converters. Simply enter the city or location you’re interested in, and the website will provide the current time in that location. Many of these sites also allow you to compare the time to other time zones, making travel planning easy.
Smartphones and Smart Watches
Most smartphones and smartwatches come equipped with built-in clock apps that automatically update to the correct time based on your location. You can also manually set your device to a specific time zone, which is useful if you’re traveling or working with people in different time zones.
The Future of Time in Colorado
While Colorado currently observes both Mountain Standard Time and Mountain Daylight Time, there is ongoing debate about whether the state should permanently switch to Mountain Standard Time or embrace a permanent DST. The arguments for each side are complex, with potential benefits and drawbacks depending on your perspective. The outcome of this debate will have a significant impact on Colorado’s relationship with time for years to come.
What Time Is It In Colorado Now
Conclusion
In summary, Colorado operates on Mountain Time (MT), which is six hours behind Coordinated Universal Time (UTC). The state’s unique history with daylight saving time has led to ongoing debates about whether to permanently switch to Mountain Standard Time or embrace a permanent DST. Understanding the time in Colorado is essential for anyone visiting or doing business in the state, and using online tools, smartphones, or smartwatches can make it easy to stay informed. Whether you’re planning a trip or simply curious about the time in the Rocky Mountains, gaining a deeper understanding of Colorado’s relationship with time will enhance your appreciation of this beautiful state and its distinct way of life.
