Arizona Time Zone: Always on Mountain Time [The Reasons Behind]
Traveling or communicating with Arizona can be a bit confusing owing to its unique time zone rules. While most of the state stays on Mountain Standard Time (MST) throughout the year, exceptions do exist, such as in the Navajo Nation.
This blog will help you navigate Arizona’s time zone quirks, offering clarity about when and where daylight saving applies within the state. Let’s dive into unraveling this geographical anomaly!
Content Highlights
- Arizona follows Mountain Standard Time (MST) all year round without observing daylight saving time.
- The Navajo Nation within Arizona follows Mountain Daylight Time (MDT) and does observe daylight saving time.
- Arizona’s decision not to observe daylight saving time is driven by factors such as extreme heat, energy conservation, and maintaining a consistent daily routine for residents.
- Traveling and communicating in Arizona may require adjustments due to the state’s unique time zone situation.
Details of Arizona Time Zone
Arizona follows two time zones depending on the season – Mountain Standard Time (MST) and Mountain Daylight Time (MDT).
Important Details of Arizona Time Zone
- Official time zone: Mountain Time Zone (MT)
- Observes Daylight Saving Time (DST): No
- UTC offset: UTC-7 (all year)
Arizona is one of only two states in the United States that does not observe Daylight Saving Time. This means that Arizona has the same time as neighboring states California and Nevada during the summer season when those states observe DST.
The Navajo Nation, located in Arizona, observes Daylight Saving Time. This means that the Navajo Nation is one hour ahead of the rest of Arizona during the summer months.
Here is a table showing the time difference between Arizona and other major US cities:
| City | Time difference |
|---|---|
| Los Angeles, CA | No difference |
| Phoenix, AZ | No difference |
| San Diego, CA | No difference |
| Seattle, WA | 1 hour ahead |
| Denver, CO | No difference |
| Chicago, IL | 1 hour ahead |
| New York, NY | 2 hours ahead |
Mountain Standard Time (MST)
Arizona uses Mountain Standard Time (MST) all year. MST is common in this state. This sets it apart from many others. Arizona does not change its clocks for daylight saving time. It sticks to MST even then.
So, while other states shift their clocks, Arizona’s time stays the same. This makes knowing the current local time easier for people in Arizona.
Mountain Daylight Time (MDT)
Mountain Daylight Time (MDT) is set at UTC -6h. This means it falls six hours behind the world’s Coordinated Universal Time. Tuba City in Arizona follows Mountain Daylight Time. However, most of the state does not keep to this time.
There are a few exceptions, though! The Navajo Nation within Arizona uses Mountain Daylight Time. They stand apart from the rest of the state by following this rule.
In Arizona, the Navajo Nation lives by Mountain Time Zone rules. This means they move their clocks one hour ahead in spring and back again in fall because the tribe follows daylight saving time.
But this is not what happens in all of Arizona! The Hopi Reservation, which lies within the Navajo Nation lands, does not use daylight saving time. They keep their time steady all year round, just like most parts of Arizona.
So be careful when you travel between these two reservations, as your clock might need to change more often than you think!

Arizona’s Unique Time Zone Situation
Arizona made the decision not to observe daylight saving time, which sets it apart from most other states.
Arizona’s choice not to observe daylight saving time
Arizona is unique because it doesn’t follow daylight saving time. This means that the clocks in Arizona don’t go forward or back like they do in other places. The decision to not observe daylight saving time was made because of the state’s unique time zone situation.
Arizona wanted to avoid confusion and inconsistencies with time across the state. So, when most people are changing their clocks for daylight saving time, people in Arizona can just keep their clocks the same all year round.
Reasons behind Arizona’s decision
Arizona has made the decision not to observe daylight saving time for several reasons. One of the main factors is the extreme heat that Arizona experiences during the summer months.
By opting out of daylight saving time, residents and businesses can avoid having to endure an extra hour of sunlight in the hottest part of the day. This helps to conserve energy and reduce strain on air conditioning systems.
Another reason behind Arizona’s decision is the impact on sleep patterns. Daylight saving time can disrupt our internal clocks, leading to less restful sleep. With Arizona’s choice not to observe it, residents can maintain a consistent schedule year-round, which can positively affect overall well-being.
In addition, not participating in daylight saving time allows businesses and schools in Arizona to save on energy bills by operating under a fixed schedule throughout the year. This consistency provides stability and convenience for both individuals and organizations within the state.
Current Local Time in Arizona
Arizona is currently observing Mountain Standard Time (MST), which is 7 hours behind Coordinated Universal Time (UTC-7).
Current time in Phoenix and other cities in Arizona
Arizona has a number of significant cities, each following the Mountain Time Zone. Below is a table detailing the current local times in some of these cities. Be aware that these times do not adjust for daylight saving, as most of Arizona does not observe it.
| City | Current Local Time |
|---|---|
| Phoenix | The current local time in Phoenix is 33 minutes ahead of the apparent solar time. |
| Tucson | Like the rest of Arizona, Tucson does not observe daylight saving time and remains on Mountain Standard Time year-round. |
| Mesa | Mesa follows the same time as the majority of the state – Mountain Standard Time, with no daylight saving time. |
| Chandler | Chandler also stays on Mountain Standard Time throughout the year without any daylight saving time. |
| Scottsdale | Scottsdale does not adjust for daylight saving time, remaining on Mountain Standard Time year-round. |
| Glendale | Glendale operates on Mountain Standard Time, with no daylight saving time. |

Arizona Time Zone Map
The Arizona Time Zone Map provides a clear visual representation of the different time zones within the state, helping to clarify the boundaries and distinctions between Mountain Standard Time (MST) and Mountain Daylight Time (MDT).
Visual representation of Arizona’s time zones
The time zones in Arizona can be a bit confusing, but a visual representation can help make things clearer. Arizona has two main time zones: Mountain Standard Time (MST) and Mountain Daylight Time (MDT).
Most of the state follows MST all year round, which means they don’t change their clocks for daylight saving time. However, some parts of Arizona switch to MDT during daylight saving time.
The Navajo Nation also has its own separate time zone, which may not align with the rest of the state. With a map showing these boundaries, it becomes easier to understand how Arizona’s different time zones are divided.
Clarifying the boundaries of each time zone
The boundaries of each time zone in Arizona depend on where you are in the state. Most of Arizona, including Phoenix, follows Mountain Standard Time (MST) annually. This means they don’t have daylight saving time, and their clocks stay the same throughout the year.
However, there is an exception for the Navajo Nation within Arizona. The Navajo Nation has its own time zone that differs from MST. So if you’re traveling through or visiting areas like Monument Valley, make sure to check the local time as it may be different from other parts of Arizona.
Time difference between Arizona and other states/countries
The time difference between Arizona and other states/countries varies because Arizona does not observe Daylight Saving Time, except within the Navajo Nation.
| Country/State | Time difference with Arizona |
|---|---|
| New York, USA | +2 hours during standard time, +3 hours during daylight saving time |
| California, USA | Same time during standard time, -1 hour during daylight saving time |
| London, UK | +7 hours during standard time, +8 hours during daylight saving time |
| Sydney, Australia | +17 hours during standard time, +18 hours during daylight saving time |
| Beijing, China | +15 hours, no daylight saving time observed |
Please note that this table represents the time difference during standard time and daylight saving time. Daylight Saving Time begins on the second Sunday in March and ends on the first Sunday in November in most parts of the United States, altering the time difference with Arizona. It’s always advisable to check the current local time in Arizona before planning any cross-time zone activities.
How Arizona’s time zone affects travel and communication
Travel and communication in Arizona can be affected due to its unique time zone situation. Unlike other states, Arizona does not observe daylight saving time. This means that while neighboring states may change their clocks for the time change, Arizona remains in Mountain Standard Time (MST) throughout the year.
This can lead to confusion when scheduling meetings or coordinating travel with individuals or businesses in different states. The time difference between Arizona and neighboring states that observe daylight saving time can vary throughout the year, causing challenges for travelers adjusting their schedules accordingly.
It’s important for visitors and residents alike to be aware of this difference to avoid any miscommunication or missed appointments.
