Time in Arizona

Time in Arizona, as in all U.S. states, is regulated by the United States Department of Transportation.

Daylight saving time

Daylight saving time in Arizona. DST regions are colored yellow.

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.^[1]

The tz database version 2016f contains two time zones for Arizona:
