What time zone is Utah in?
All of Utah is in the Mountain Time Zone. Utah observes daylight saving time, so it is on Mountain Standard Time (MST, UTC-7) from early November to mid-March and Mountain Daylight Time (MDT, UTC-6) from mid-March to early November. The whole state uses the same clock, from St. George to Salt Lake City to Logan.
Utah sits inside the Mountain Time Zone set by the U.S. Department of Transportation, whose federal time zone boundary rule takes in the entire state. Colorado, Wyoming, New Mexico and most of Idaho share the same clock. On SGWOM, every event time in the St. George events calendar is listed in Mountain Time.
Is Utah on MST or MDT right now?
Utah moved its clocks back one hour at 2 a.m. on Sunday, November 1, 2026, so it is on Mountain Standard Time (UTC-7) until 2 a.m. on Sunday, March 14, 2027. That morning clocks spring forward to Mountain Daylight Time (UTC-6), which lasts until 2 a.m. on Sunday, November 7, 2027.
Those dates come from federal law. Since 2007, the Uniform Time Act has set daylight saving time to start at 2 a.m. on the second Sunday of March and end at 2 a.m. on the first Sunday of November. Utah follows that schedule.
| Period | Utah time | Offset |
|---|---|---|
| Nov. 1, 2026 to Mar. 14, 2027 | Mountain Standard Time (MST) | UTC-7 |
| Mar. 14, 2027 to Nov. 7, 2027 | Mountain Daylight Time (MDT) | UTC-6 |
What time zone is Salt Lake City in?
Salt Lake City is on Mountain Time, the same as the rest of Utah: MST (UTC-7) in winter and MDT (UTC-6) in summer. There is no time difference between Salt Lake City and St. George at any time of year.
The time in St. George, Cedar City, Hurricane, Kanab and Moab is exactly the same as in Salt Lake City. If your phone shows a different time after a drive, it has likely picked up a cell tower across the Nevada or Arizona line.
Time difference between St. George and nearby states
This is where Southern Utah gets confusing. St. George sits a few miles from both Nevada and Arizona, and neither shares Utah's clock all year. Nevada is on Pacific Time. Most of Arizona never changes its clocks, because federal law lets a state that lies entirely in one time zone stay on standard time year-round, and Arizona has chosen to.
| Place | Early Nov. to mid-March | Mid-March to early Nov. |
|---|---|---|
| Mesquite, NV and Las Vegas, NV (Pacific Time) | 1 hour behind | 1 hour behind |
| Valley of Fire State Park, NV | 1 hour behind | 1 hour behind |
| Grand Canyon North Rim, AZ | Same time | 1 hour behind |
| Page, Horseshoe Bend and Fredonia, AZ | Same time | 1 hour behind |
| Phoenix and Scottsdale, AZ | Same time | 1 hour behind |
| Navajo Nation, incl. Monument Valley | Same time | Same time |
| Hopi Reservation, AZ | Same time | 1 hour behind |
| Salt Lake City, Kanab and the rest of Utah | Same time | Same time |
| Los Angeles, CA | 1 hour behind | 1 hour behind |
| Chicago, IL (Central Time) | 1 hour ahead | 1 hour ahead |
| New York, NY (Eastern Time) | 2 hours ahead | 2 hours ahead |
Times are relative to Utah. "1 hour behind" means it is an hour earlier there than in St. George.
Driving to Mesquite or Las Vegas
Crossing into Nevada on I-15 south of St. George, you gain an hour all year. A 7 p.m. show in Mesquite starts at 8 p.m. St. George time. Coming home, a 5 p.m. Nevada departure puts you back in St. George around 6:35 p.m. Utah time on the 35-minute drive, so plan dinner reservations and pickups with the hour in mind. Our St. George to Mesquite guide has the route and drive time.
Driving to the Grand Canyon, Page or Lake Powell
In winter, northern Arizona and Utah show the same time. From mid-March to early November, most of Arizona is an hour behind Utah, so a Grand Canyon tour that starts at 10 a.m. Arizona time starts at 11 a.m. St. George time. Check which time zone your tour or ticket is written in before you leave. See our St. George to Grand Canyon guide and the Page, Arizona drive guide.
The Navajo Nation exception
The Navajo Nation, which covers much of northeastern Arizona and reaches into southeastern Utah, does observe daylight saving time, so it matches Utah all year, including at Monument Valley. The Hopi Reservation, which is surrounded by the Navajo Nation, follows the rest of Arizona and does not change its clocks. The AP has reported that in summer, a drive across the region can mean changing time zones several times.
Is Utah getting rid of daylight saving time?
Not yet. Utah passed S.B. 59 in 2020 to stay on daylight saving time all year, but it only takes effect if Congress changes federal law to allow it and at least four other western states pass similar laws. Neither has happened, so Utah still changes its clocks twice a year. A 2025 bill to move Utah to permanent standard time instead did not pass.
The 2020 law, S.B. 59, Daylight Saving Time Amendments, would put all of Utah on Mountain Daylight Time year-round. Its two conditions are written into the bill: Congress has to amend 15 U.S.C. 260a to let states observe daylight time all year, and at least four western states besides Utah have to pass similar laws. Federal law today only allows the opposite, staying on standard time year-round, which is what Arizona does. In 2025, H.B. 120 proposed moving Utah to permanent standard time instead; it did not pass. We will update this page if either changes.
