About converting MST to UTC

Mountain Time (Denver) and Coordinated Universal Time (UTC) are in different time zones, so a meeting, call or stream that's convenient in one may be early or late in the other. The clocks above update live and account for daylight saving automatically, so the time difference you see is the real one for today — not a fixed number that goes stale twice a year.

To plan across the two, type a time into the MST box (or tap a quick preset) and read the UTC equivalent, including a "next day" or "previous day" note when the conversion crosses midnight. For any other pair of zones or cities, use the full timezone converter.

MST vs UTC: the time difference through the year

The gap between MST and UTC changes during the year because only one of them uses daylight saving.

Best time to meet

The two zones

MST · Mountain Time

Mountain Time is UTC−7 in winter (MST) and UTC−6 in summer (MDT) for Denver, Salt Lake City and Calgary. Most of Arizona stays on MST (UTC−7) all year.

UTC · Coordinated Universal Time

Coordinated Universal Time (UTC) is the world's time standard, kept by atomic clocks. It never changes for daylight saving.

Frequently asked questions

6 answers
What is the time difference between MST and UTC?
It's shown live at the top of this page (and it can change with daylight saving). The converter uses the current, DST-aware difference between Mountain Time and Coordinated Universal Time, so the time you see is always right for right now.
How do I convert MST to UTC?
Enter a time in the MST box and the equivalent UTC time appears instantly, adjusted for the current offset between the two zones — including a note if it lands on the previous or next day.
Is this MST to UTC converter accurate with daylight saving?
Yes. It uses your browser's built-in time-zone database (the IANA zones behind Denver and UTC), which tracks daylight-saving changes automatically, so the current times and difference are correct.
What time is it in UTC right now?
The live clock above shows the current time in UTC (UTC), updating every second, alongside MST.
Does the MST to UTC time difference change?
Yes. Over the next 12 months it is 6 h ahead or 7 h ahead, depending on the date — see the table of periods on this page.
What is a good meeting time for MST and UTC?
Office hours overlap from 9:00 AM to 11:00 AM MST (3:00 PM to 5:00 PM UTC).
