Current Time in GMT − 7 Zone
About GMT-7
GMT-7 is seven hours behind Greenwich Mean Time. This offset is used for Mountain Standard Time (MST) in parts of the US and Canada, including cities like Denver and Calgary during the winter. Notably, the state of Arizona uses MST year-round. During the summer, this offset becomes Pacific Daylight Time (PDT) for the entire US and Canadian West Coast.
UTC Offset: GMT-7
What is GMT-7?
GMT-7 means Greenwich Mean Time 7 hours behind the Greenwich meridian, the historical reference line running through the Royal Observatory in London. GMT offsets are the everyday way many countries, broadcasters, and travel timetables describe their local time relative to the UK.
Note that some of the countries listed below sit on GMT-7 for only part of the year: when daylight saving time starts or ends they move one hour, so always check the live local times shown on this page or on each country's own page.
GMT-7 vs UTC-7
For everyday purposes GMT-7 and UTC-7 are the same wall-clock time. GMT is the traditional name based on mean solar time at Greenwich, while UTC is the modern atomic-time standard used by computers and aviation. If you are setting a meeting or catching a flight, either works; if you are configuring a server, use UTC-7.

GMT-7: The Mountain Time Offset and Its Fixed UTC-7 Regions
GMT-7 is a fixed UTC offset of 7 hours behind Coordinated Universal Time (UTC). Unlike named time zones such as Mountain Standard Time (MST), which may observe daylight saving time (DST) and shift to UTC-6 in summer, GMT-7 as a pure offset does not change. This page covers the regions that permanently or seasonally use UTC-7, including parts of Canada, Mexico, and the United States, and explains how this offset relates to the broader timekeeping system.
Fixed UTC Offset vs. Named Time Zone
A fixed UTC offset like GMT-7 is simply a number: it tells you that clocks in that zone are always 7 hours behind UTC. A named time zone, such as Mountain Standard Time (MST), is a political and geographical area that may apply different offsets at different times of the year. For example, MST is UTC-7 during standard time, but regions that observe DST switch to Mountain Daylight Time (MDT, UTC-6) from spring to fall. Therefore, the list of countries and regions on GMT-7 is not static; it changes seasonally as DST-observing areas move on and off this offset.
Countries and Regions Currently on GMT-7
- Canada: Parts of British Columbia (including Dawson Creek, Fort Nelson, Creston), Yukon (Whitehorse, Dawson), Northwest Territories (Inuvik, Cambridge Bay), and Alberta (Edmonton, Calgary area). Note that most of Alberta observes DST, so it is on UTC-7 only during winter; in summer it shifts to UTC-6.
- Mexico: The state of Sonora (Hermosillo) and the state of Sinaloa (Mazatlan) are on UTC-7 year-round. Most of Mexico observes DST, but these states do not.
- United States: The Mountain Time Zone states, including Arizona (Phoenix) – which does not observe DST – and parts of Idaho (Boise), Colorado (Denver), Montana, New Mexico, Utah, Wyoming, and others. Most of these states observe DST, so they are on UTC-7 only during winter; in summer they shift to UTC-6.
Representative Cities on GMT-7
- Year-round UTC-7: Phoenix (Arizona, USA), Hermosillo (Sonora, Mexico), Mazatlan (Sinaloa, Mexico), Creston (British Columbia, Canada), Fort Nelson (British Columbia, Canada), Dawson Creek (British Columbia, Canada).
- Seasonal UTC-7 (winter only): Denver (Colorado, USA), Boise (Idaho, USA), Edmonton (Alberta, Canada), Whitehorse (Yukon, Canada), Inuvik (Northwest Territories, Canada), Cambridge Bay (Nunavut, Canada).
IANA Time Zones at GMT-7
The IANA time zone database includes the following zones that use UTC-7 as their standard offset: America/Boise, America/Cambridge_Bay, America/Ciudad_Juarez, America/Creston, America/Dawson, America/Dawson_Creek, America/Denver, America/Edmonton, America/Fort_Nelson, America/Hermosillo, America/Inuvik, America/Mazatlan, America/Phoenix, America/Whitehorse, Canada/Mountain, US/Arizona, US/Mountain. Note that some of these zones (like America/Denver) observe DST, so their actual offset changes twice a year.
Practical Scheduling Notes
When scheduling across GMT-7, remember that many locations in this offset observe DST. During winter (November to March), most of the Mountain Time zone is on UTC-7. During summer (March to November), those areas shift to UTC-6. However, regions like Arizona and Sonora stay on UTC-7 year-round. So a meeting at 10:00 AM in Phoenix (UTC-7) is 11:00 AM in Denver (UTC-6 in summer). Always check the current offset for the specific city. The military designation for UTC-7 is Tango (T). UTC and GMT are functionally identical for timekeeping; GMT-7 and UTC-7 read the same on a clock.
Frequently Asked Questions
What is the difference between GMT-7 and Mountain Standard Time (MST)?
GMT-7 is a fixed offset of 7 hours behind UTC. MST is a named time zone that uses GMT-7 during standard time, but regions observing DST switch to Mountain Daylight Time (MDT, UTC-6) in summer. So MST is not always the same as GMT-7; only areas that do not observe DST (like Phoenix) are always on GMT-7.
Which major cities are permanently on GMT-7?
Phoenix (Arizona, USA), Hermosillo (Sonora, Mexico), Mazatlan (Sinaloa, Mexico), Creston (British Columbia, Canada), Fort Nelson (British Columbia, Canada), and Dawson Creek (British Columbia, Canada) are on GMT-7 year-round.
Does all of Canada use GMT-7 in winter?
No, only parts of Canada use GMT-7. These include most of Alberta, parts of British Columbia (like Dawson Creek and Fort Nelson), Yukon, and the Northwest Territories. However, many of these areas observe DST, so they switch to UTC-6 in summer.
What is the military time zone letter for GMT-7?
The military letter for UTC-7 is Tango (T). It is used in aviation and military operations to denote the offset.
If I have a meeting at 3:00 PM GMT-7, what time is it in New York (UTC-5)?
New York is on Eastern Time, which is UTC-5 during standard time and UTC-4 during daylight time. If New York is on standard time, 3:00 PM GMT-7 is 5:00 PM EST. If New York is on daylight time, it is 6:00 PM EDT. Always check the current DST status.
Is GMT-7 the same as UTC-7?
Yes, GMT and UTC are functionally identical for everyday timekeeping. Both refer to the same time standard, so GMT-7 and UTC-7 read the same on a clock.
