Arizona Time Zone

The Arizona Time Zone is the Mountain Standard Time (MST) zone. The Mountain Standard Time Zone is 7 hours behind UTC (Universal Time, Coordinated).

Arizona does not observe Daylight Saving Time (March through November). During Daylight Saving Time (DST) most of Arizona is at the same time as California (Pacific Daylight Time or PDT). From the first Sunday in November through the second Sunday in March Arizona is one hour ahead of those states on Pacific Standard Time, like California and Nevada; one hour behind states in the Central Time Zone, such as Texas and Illinois; and only two hours behind those states on Eastern Time, such as New York and Florida. The only exception in Arizona is the Navajo Nation, in northeastern Arizona, which does observe Daylight Saving Time.
