Welcome to our guide on Daylight Savings Time in Arizona. Unlike most of the United States, Arizona does not observe Daylight Savings Time (DST), choosing instead to remain on Mountain Standard Time (MST) year-round. This unique timekeeping choice means that Arizona does not "spring forward" or "fall back" with the clock changes in spring and fall. However, there are exceptions: the Navajo Nation in northeastern Arizona does observe DST, aligning with neighboring states. This section will help you understand how Arizona's approach to timekeeping impacts daily life, travel, and communication, making it easier for residents and visitors alike to navigate the state's diverse time zones.
The Navajo Nation Exception ?
The Navajo Nation (northeastern Arizona) does observe DST, so during DST months the Navajo clock is one hour ahead of the rest of Arizona.
Travel tip: the Hopi Reservation (entirely surrounded by the Navajo Nation) does not observe DST and remains on MST year-round, creating a "time island" for travelers.
Impact on Visitors and Communication?
- Flight times: Confirm whether times are listed in local Arizona time (MST) or your departure city's time. Phoenix Sky Harbor (PHX) operates on MST year-round.
- Road trips: Phones may auto-switch near Navajo borders. Verify times manually when in doubt.
- Business hours: In summer, Mountain Time states (e.g., Utah, Colorado) are one hour ahead of most of Arizona.
