Arizona does not observe daylight saving time and stays on Mountain Standard Time (MST, UTC−7) year-round. The state legislature opted out of DST in 1968, largely because adding an extra hour of evening sunlight in an already very hot climate was seen as a burden rather than a benefit.
During DST months (mid-March to early November), the rest of the Mountain Time zone springs forward to MDT (UTC−6), so Arizona ends up one hour behind Denver and Albuquerque. During those same months Arizona's clocks match Pacific Daylight Time, so Los Angeles and Phoenix show the same time. From November through March, Arizona is one hour ahead of Los Angeles and matches the rest of the Mountain Time zone.
No. Arizona is the only contiguous US state that does not observe daylight saving time. The state stays on Mountain Standard Time (MST, UTC−7) every day of the year. The exception is the Navajo Nation in northeastern Arizona, which does observe DST and is therefore one hour ahead of the rest of Arizona from mid-March to early November.
Arizona is always in the Mountain Standard Time (MST) zone, UTC offset −7. Because it skips DST, it effectively aligns with Pacific Daylight Time (PDT) in summer and Mountain Standard Time (MST) in winter — matching a different set of US cities depending on the time of year.
During daylight saving time (approximately March–November), yes — Arizona and California show the same clock time. During standard time (approximately November–March), Arizona is one hour ahead of California.
Use the converter above to find the current Arizona time. A good rule of thumb: during DST months, Arizona matches Pacific Time; during standard-time months, Arizona matches Mountain Time. Reasonable calling hours are generally 8 AM – 9 PM local Arizona time.
The Navajo Nation spans northeastern Arizona as well as parts of Utah and New Mexico. Unlike the rest of Arizona, the Navajo Nation does observe daylight saving time. During DST months, the Navajo Nation is one hour ahead of the surrounding Arizona land. The Hopi Reservation, which is entirely surrounded by the Navajo Nation, follows Arizona's lead and does not observe DST, creating a patchwork of time zones within a small geographic area.
In the US, DST begins on the second Sunday in March (clocks spring forward one hour at 2:00 AM) and ends on the first Sunday in November (clocks fall back one hour at 2:00 AM). Arizona ignores both transitions.
