MST to UTC — Time Zone Converter
Mountain Time (MST, UTC−7) covers the US Mountain states; Coordinated Universal Time (UTC, UTC+0) covers the global reference timeline. In standard time, UTC is 7 hours ahead of MST. Mornings in the US Mountain states overlap with afternoons in the global reference timeline, which keeps both sides inside office hours. Use the live converter below — it applies today's IANA time zone data, including daylight saving time, and gives you a meeting schedule you can paste straight into email or Slack.

Frequently asked questions
What is the time difference between MST and UTC?+
Mountain Time (MST) is UTC−7 and Coordinated Universal Time (UTC) is UTC+0, so in standard time UTC is 7 hours ahead of MST. The gap shifts by an hour around daylight saving transitions, so always check a live converter near the change dates in spring and autumn.
Does MST or UTC observe daylight saving time?+
Mountain Time observes daylight saving time (MST in winter, MDT in summer). Coordinated Universal Time stays on UTC+0 all year — no daylight saving time.
What is the best time for a meeting between MST and UTC?+
Mornings in the US Mountain states overlap with afternoons in the global reference timeline, which keeps both sides inside office hours. The converter above highlights office hours in green for both zones, so you can slide to a time that works for everyone.
How do I share a MST to UTC meeting time by email?+
Pick a time in the converter, log it to the Smart Clipboard, and copy it as bullets, a formatted table, or a one-line question — with both MST and UTC times spelled out so nobody has to do the math.
