Mountain Time

Mountain Time covers Denver, Salt Lake City, Calgary and much of the US interior west.

--:--:--

Mountain Time is UTC−7 in winter (MST) and UTC−6 in summer (MDT).

Arizona is the well-known exception: most of the state stays on Mountain Standard Time all year and does not change its clocks, which means Phoenix matches Denver in winter and Los Angeles in summer.
