UTC to MST Full 24-Hour Conversion Table
Mountain Standard Time (MST) is fixed at 7 hours behind Coordinated Universal Time, written as UTC−7. To convert any UTC time to MST, subtract 7 hours:
$$\text{MST} = (\text{UTC Hour} - 7) \bmod 24$$
Because of the subtraction, every UTC hour from 00:00 to 06:00 rolls back to the previous calendar day in MST (marked “− 1 day” below). For example, 03:00 UTC converts to 20:00 MST on the previous day.

| 00:00 | 17:00 | 5:00 PM | − 1 day |
| 01:00 | 18:00 | 6:00 PM | − 1 day |

Minutes are unchanged by the conversion because MST differs from UTC by a whole number of hours; only the hour (and sometimes the date) changes.
Key Terms: UTC, MST and MDT
- UTC (Coordinated Universal Time)
- The primary time standard by which the world regulates clocks and time. UTC does not change with the seasons and serves as the reference point (offset 0) from which all time zones are defined. It is closely aligned with Greenwich Mean Time (GMT).
- MST (Mountain Standard Time, UTC−7)
- The standard time observed in the Mountain Time Zone of North America during the winter months. It is fixed at 7 hours behind UTC. Arizona (outside the Navajo Nation) uses MST year-round because it does not observe daylight saving time.
- MDT (Mountain Daylight Time, UTC−6)
- The daylight saving variant of Mountain Time, used in most of the zone (e.g., Colorado, Utah, Montana) from spring to fall. It is 6 hours behind UTC — one hour ahead of MST. When daylight saving is in effect, convert UTC by subtracting 6 hours instead of 7.
- Fixed UTC offset
- A constant difference between a local time and UTC, expressed as UTC±hh:mm. A fixed offset such as UTC−7 stays the same all year and ignores daylight saving transitions, which makes conversions straightforward: simply add or subtract the offset. “Mountain Time” as observed by people, however, switches between MST (UTC−7) and MDT (UTC−6) across the year.
Frequently Asked Questions
What is the time difference between UTC and MST?
Mountain Standard Time (MST) is 7 hours behind Coordinated Universal Time, written as UTC-7. To convert UTC to MST, subtract 7 hours from the UTC time. For example, 14:00 UTC becomes 07:00 MST. This 7-hour gap stays constant whenever standard time is in effect.
How do I convert UTC to MST manually?
Subtract 7 hours from the UTC time. If the result is negative, add 24 hours and move to the previous calendar day. For example, 03:00 UTC minus 7 hours equals 20:00 MST the prior day. For times after 07:00 UTC, the date stays the same.
What is 10 UTC in MST?
10:00 UTC equals 03:00 MST, since MST is 7 hours behind UTC. Subtracting 7 from 10 gives 3, so it is 3:00 AM Mountain Standard Time on the same calendar day. No date change occurs because the result remains above zero.
What is 2pm UTC in MST?
2:00 PM UTC (14:00) equals 7:00 AM MST. Subtracting the 7-hour offset from 14:00 gives 07:00, which is 7:00 AM Mountain Standard Time on the same day. The conversion keeps the same calendar date because the result stays positive.
Does MST change for daylight saving time?
MST itself does not change; it is always UTC-7. However, most Mountain regions switch to Mountain Daylight Time (MDT), which is UTC-6, during summer. Arizona (except the Navajo Nation) stays on MST year-round. Make sure you want MST specifically, not the locally observed time, which may be MDT.
Which places use Mountain Standard Time?
MST covers parts of the United States, Canada and Mexico, including Colorado, Utah, Montana, Wyoming, New Mexico and much of Arizona, plus Alberta and parts of Sonora, Mexico. Arizona observes MST all year, while other Mountain zones shift to MDT in summer.
