Knowing the current time is essential, especially when you’re coordinating across different regions. If you’ve ever wondered, “What Time Is It Mt?”, you’re likely trying to understand Mountain Time (MT). This time zone plays a crucial role across a significant portion of North America and even extends into Mexico. Spanning from northern Canada down to Mexico, Mountain Time is geographically vast, though it’s the least populated time zone in the United States. Understanding MT is key for anyone working, traveling, or connecting with people in this zone.
Defining Mountain Time (MT)
Mountain Time isn’t a fixed time; instead, it designates a geographical area that adjusts its time twice a year with Daylight Saving Time (DST). This means Mountain Time can refer to either Mountain Standard Time (MST) or Mountain Daylight Time (MDT) depending on the season.
- Mountain Standard Time (MST), observed during the winter months, is equivalent to UTC-7.
- Mountain Daylight Time (MDT), used during the summer months when DST is in effect, is UTC-6.
Similar to other North American time zones like Pacific Time (PT), Central Time (CT), Eastern Time (ET), and Atlantic Time (AT), Mountain Time provides a general term for the time observed in this region. It’s bordered by Central Time to the east and Pacific Time to the west, creating time differences that are important to recognize.
Where is Mountain Time Observed?
Mountain Time is observed across a wide range of locations. The specific areas can be broken down by country and whether they observe DST or remain on MST year-round.
US States in Mountain Time (MST/MDT)
Many US states observe Mountain Time, switching between MST in the winter and MDT in the summer. These include:
- Arizona – It’s important to note that this only applies to the Navajo Nation within Arizona. Most of Arizona does not observe Daylight Saving Time and remains on MST year-round, which is equivalent to Pacific Daylight Time (PDT) during summer.
- Colorado – The entire state of Colorado observes Mountain Time with DST.
- Idaho – Most of Idaho is in the Mountain Time Zone, excluding western counties such as Benewah, Bonner, Boundary, Clearwater, Kootenai, Latah, Lewis, Nez Perce, Shoshone, and the northern part of Idaho which are in Pacific Time.
- Kansas – Only a few western counties of Kansas, specifically Greeley, Hamilton, Sherman, and Wallace, observe Mountain Time.
- Montana – The entire state of Montana is on Mountain Time.
- Nebraska – Western counties of Nebraska, including Arthur, Banner, Box Butte, Chase, Cheyenne, Dawes, Deuel, Dundy, Garden, Grant, Hooker, Keith, Kimball, Morrill, Perkins, Scotts Bluff, Sheridan, Sioux, and the western part of Cherry County, observe Mountain Time.
- New Mexico – The entire state of New Mexico is in the Mountain Time Zone.
- North Dakota – South-western parts of North Dakota, specifically the counties of Adams, Billings, Bowman, Golden Valley, Grant, Hettinger, Mercer, Slope, and Stark, and southern parts of Dunn and McKenzie, most of Morton and Sioux counties observe Mountain Time.
- Oregon – Only a small part of Malheur County in Oregon is within the Mountain Time Zone. The rest of Oregon observes Pacific Time.
- South Dakota – Western counties of South Dakota, such as Bennett, Butte, Corson, Custer, Dewey, Fall River, Haakon, Harding, Jackson, Lawrence, Meade, Pennington, Perkins, Shannon, and Ziebach, and the western parts of Stanley County, are on Mountain Time.
- Texas – A few counties in western Texas, El Paso and Hudspeth, and part of Culberson County, observe Mountain Time.
- Utah – The entire state of Utah is within the Mountain Time Zone.
- Wyoming – The entire state of Wyoming observes Mountain Time.
Canadian Provinces/Territories in Mountain Time (MST/MDT)
Several Canadian provinces and territories also observe Mountain Time with DST:
- Alberta – The entire province of Alberta is on Mountain Time.
- British Columbia – A few eastern communities in British Columbia, including Cranbrook, Golden, and Invermere, observe Mountain Time.
- Northwest Territories – The majority of the Northwest Territories is within the Mountain Time Zone.
- Nunavut – Only Kugluktuk and Cambridge Bay in Nunavut observe Mountain Time. Other parts of Nunavut are on Eastern Time.
- Saskatchewan – Only the city of Lloydminster and its surrounding area in Saskatchewan observe Mountain Time. Most of Saskatchewan does not observe DST and remains on Central Standard Time (CST) year-round.
Mexican States in Mountain Time (MST/MDT)
Mountain Time also extends into Mexico:
- Baja California Sur – The state of Baja California Sur observes Mountain Time.
- Chihuahua – The state of Chihuahua is on Mountain Time.
- Nayarit – The state of Nayarit observes Mountain Time.
- Sinaloa – The state of Sinaloa is within the Mountain Time Zone.
Locations Observing MST Year-Round
Some areas within the Mountain Time zone do not observe Daylight Saving Time and remain on MST throughout the year.
Mexican States Observing MST Year-Round
- Sonora – The state of Sonora in Mexico remains on MST all year.
Canadian Provinces/Territories Observing MST Year-Round
- British Columbia – Certain locations in British Columbia, including Creston, the Northern Rockies Regional Municipality, and most of the Peace River Regional District (except Fort Ware), observe MST year-round.
- Yukon – The entire Yukon territory is on MST year-round.

Converting Mountain Time to Other Time Zones
When considering “what time is it mt?”, it’s often helpful to understand how it relates to other time zones.
- Mountain Time vs. Pacific Time: Mountain Time is one hour ahead of Pacific Time. So, if it’s 10:00 AM PT, it’s 11:00 AM MT.
- Mountain Time vs. Central Time: Central Time is one hour ahead of Mountain Time. If it’s 11:00 AM MT, it’s 12:00 PM CT.
- Mountain Time vs. Eastern Time: Eastern Time is two hours ahead of Mountain Time. If it’s 10:00 AM MT, it’s 12:00 PM ET.
To easily convert Mountain Time to other time zones, you can use a time zone converter. These tools are readily available online and can quickly show you the current time in Mountain Time relative to any other time zone in the world.
Conclusion
Understanding “what time is it mt?” involves knowing about Mountain Time, its variations between MST and MDT, and the extensive regions where it is observed. From the US Mountain states to parts of Canada and Mexico, Mountain Time is a significant time zone in North America. Whether you’re scheduling a call, planning travel, or just curious about the time, knowing the specifics of Mountain Time is incredibly useful.
