Current time in Arizona
Mountain Standard Time UTC−7 · no DST
Arizona's time zone
Arizona keeps Mountain Standard Time (MST, UTC−7) every day of the year. The state opted out of daylight saving in 1968, so its clocks never change — in winter Arizona matches Mountain Time cities like Denver, and in summer it lines up with Pacific Time cities like Los Angeles.
The exception is the Navajo Nation in the state's northeast, which observes DST to stay consistent with its sections in Utah and New Mexico. The Hopi Reservation, entirely surrounded by Navajo land, follows the rest of Arizona and skips DST — so on some summer drives through the northeast the hour can change more than once.

Frequently asked questions
Is the time the same everywhere in Arizona?
Mostly. The state keeps MST year-round, but the Navajo Nation does observe DST, so it runs an hour ahead of the rest of Arizona from March to November.
What's the time difference between Arizona and California?
In winter Phoenix is 1 hour ahead of Los Angeles; in summer both read the same time, because California springs forward and Arizona doesn't. Full chart: MST to PST.
Does Arizona observe daylight saving time?
No — not since 1968, apart from the Navajo Nation. See who else skips DST on the DST page.
