Utah is Mountain Time statewide (MST/MDT, UTC−7 in winter, UTC−6 in summer), with no Pacific or Central areas; its city Salt Lake City follows the same clock.
Crossing the state line
Utah’s western neighbor Nevada is on Pacific Time, one hour behind Salt Lake City — except West Wendover on the state line, which follows Mountain Time. In summer most of Arizona, which skips daylight saving, is also an hour behind Utah, though the Navajo Nation matches Utah year-round.
