What is MST in UTC?
Coordinated Universal Time is 6 hours ahead
Mountain Time is on UTC−6:00 and Coordinated Universal Time is on UTC+0:00 right now. Mountain Time is on daylight saving, so its clocks read MDT. The gap changes during the year — see below.

When the difference changes
Mountain Time and Coordinated Universal Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:
- Now – November 1, 2026Coordinated Universal Time is 6 hours ahead
- November 1, 2026 – March 14, 2027Coordinated Universal Time is 7 hours ahead
- March 14, 2027 – onwardsCoordinated Universal Time is 6 hours ahead
Periods shorter than a day are not listed: both zones change at 2am in their own local time, so there are a few hours on each transition date when the gap is briefly something else.
Daylight saving
Mountain Time
Clocks go back one hour at 2am local time, becoming MST.
Coordinated Universal Time
Coordinated Universal Time stays on UTC all year, so its offset from UTC never moves.
MST to UTC conversion table
Every hour of Tuesday, September 22, 2026, converted from Mountain Time to Coordinated Universal Time. 6 of the 24 hours fall on a different calendar day in the prime meridian, which is marked.

Scheduling between the two
Working hours overlap from 9:00 am to 12:00 pm MDT, which is 3:00 pm to 6:00 pm UTC. Anything inside that window falls in the normal working day at both ends.
Mountain Time (MDT) is used in Salt Lake City, Albuquerque and Calgary. Arizona keeps MST all year and does not follow MDT.
Coordinated Universal Time (UTC) is used in aviation, computing, and science worldwide. UTC never changes for daylight saving.
