UTC to MST converter
UTC never changes for daylight saving time, but Mountain Time does, so the gap moves by an hour twice a year. The table below always shows the right one for your date.
Convert Coordinated Universal Time (UTC) to Mountain Standard Time (MST) for any date and time.
Mountain Time is 6 hours behind UTC from March to November, and 7 hours behind the rest of the year.
Right now UTC is UTC+0 and Mountain Time is on MDT (UTC−6). Mountain Time switches back to standard time on 1 November 2026.
US clocks go back on 1 November 2026. From then, MST is 7 hours behind UTC.
9:00 am to 5:00 pm UTC is 3:00 am to 11:00 am MDT.
- 8:00 am UTC is 2:00 am MDT

Your working hours overlap for 2 hours, from 3:00 pm UTC (9:00 am MDT) to 5:00 pm UTC (11:00 am MDT). That's the best window for a meeting.
About these time zones
UTC: Coordinated Universal Time
Coordinated Universal Time is UTC+0.
The world's reference time. Every other zone is defined as an offset from UTC, and it never changes for daylight saving time. Servers, aviation and international deadlines use it.
MST: Mountain Standard Time
Mountain Standard Time is UTC−7. MST is also used for Malaysia Standard Time (UTC+8). This page converts US Mountain Time.
Colorado, Utah, New Mexico, Wyoming, Montana and southern Idaho, plus Alberta in Canada. Most of Arizona stays on MST all year (the Navajo Nation follows daylight saving time). MT is the short form for the whole zone.
Most places on Mountain Time are on MDT (UTC−6) right now, not MST. People still say "MST" all year, so the times on this page follow the clocks and show MDT until 1 November 2026.
How the difference changes
Right now MDT is 6 hours behind UTC. From 1 November 2026, when US clocks go back, the difference becomes 7 hours. From 14 March 2027, when US clocks go forward, the difference becomes 6 hours.
