Time in Arizona
Daylight saving time
Unlike most of the United States, Arizona does not observe daylight saving time (DST), with the exception of the Navajo Nation, which does observe DST. The Hopi Reservation, which is not part of the Navajo Nation but is geographically contained within it, does not observe DST.
The tz database version 2012c contains two time zones for Arizona:
