How time works in Arizona
Arizona does not observe daylight saving time: it stays on Mountain Standard Time (UTC −07:00) all year. In summer that puts Phoenix on the same clock as Los Angeles; in winter it matches Denver.
The Navajo Nation in the northeast of the state is the exception and does move its clocks forward in summer. The Hopi Reservation, which lies within the Navajo Nation, does not.
