About converting UTC to MST

Coordinated Universal Time (UTC) and Mountain Time (Denver) 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 UTC box (or tap a quick preset) and read the MST 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.

UTC vs MST: the time difference through the year

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

Best time to meet

The two zones

UTC · Coordinated Universal Time

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

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.

Frequently asked questions

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