So you're planning a trip to the Grand Canyon or maybe relocating to Phoenix, and suddenly you wonder – what time is it actually in Arizona? Let me tell you, this isn't as straightforward as you'd think. I learned this the hard way when I missed a virtual meeting with a client in Tucson because my calendar automatically adjusted for daylight saving. Total facepalm moment. Arizona's time situation is quirky enough that even locals sometimes get tripped up. Let's break this down in plain English.
Arizona's Official Time Zone (Mostly)
Here's the deal: most of Arizona runs on Mountain Standard Time (MST) year-round. That's UTC-7 during standard time. But here's where things get weird – while other states spring forward and fall back, Arizona mostly doesn't. That's right, no daylight saving time adjustments for the majority of the state.
| Location | Time Zone | Observes DST? | UTC Offset (Winter) |
|---|---|---|---|
| Phoenix | MST | No | UTC-7 |
| Tucson | MST | No | UTC-7 |
| Flagstaff | MST | No | UTC-7 |
| Navajo Nation | MDT | Yes | UTC-6 |
I've got a buddy who moved from California to Scottsdale last year. For half the year, he kept showing up an hour early for Zoom calls because he forgot Arizona doesn't do the DST dance. Pretty funny until it's your paycheck on the line.
Key takeaway: When people search what is the time zone of Arizona, they're usually asking why Arizona feels "off" compared to neighboring states for half the year. It's because they're comparing to states that do observe DST.
Why Arizona Hates Daylight Saving Time
Ever wonder why Arizona bucks the national trend? Turns out it's not some modern conspiracy – this dates back to 1968. The state legislature basically said "enough is enough" with clock changes. Their reasoning? With our blistering summers, extending evening daylight just means more air conditioning costs and unhappy residents. I mean, would YOU want an extra hour of 115°F heat?
There's also this great story about lobbyists from the drive-in movie industry. Apparently they argued that later sunsets meant people wouldn't come out until after 9pm – cutting into prime movie time. Whether that's true or not, it makes for a good bar tale in Flagstaff.
The Navajo Nation Exception
Here's where it gets messy. The Navajo Nation, which occupies parts of northern Arizona, does observe daylight saving time. So from March to November, they're on Mountain Daylight Time (MDT, UTC-6). Meanwhile, the Hopi Reservation inside Navajo land doesn't change clocks. Confused yet?
| Town | County | Time Zone (Nov-Mar) | Time Zone (Mar-Nov) |
|---|---|---|---|
| Tuba City | Navajo Nation | MST (UTC-7) | MDT (UTC-6) |
| Window Rock | Navajo Nation | MST (UTC-7) | MDT (UTC-6) |
| Second Mesa | Hopi Reservation | MST (UTC-7) | MST (UTC-7) |
I once drove from Page to Flagstaff in late April and changed time zones three times without crossing state lines. My phone couldn't decide what time it was and gave up entirely. If you're road-tripping through Navajo country, set your watch manually!
How Arizona Compares to Neighboring States
This is where Arizona's time zone really gets interesting. Depending on the time of year, you could be in the same time zone as California or Colorado. Wrap your head around this:
| Season | Arizona Time | California Time | Colorado Time | Practical Effect |
|---|---|---|---|---|
| Nov-Mar | MST (UTC-7) | PST (UTC-8) | MST (UTC-7) | Same as CO, +1hr ahead of CA |
| Mar-Nov | MST (UTC-7) | PDT (UTC-7) | MDT (UTC-6) | Same as CA, -1hr behind CO |
So in summer, when California springs forward, Arizona suddenly aligns with LA time even though we're technically in the mountain time zone. But Colorado jumps ahead, so Denver is an hour ahead of Phoenix from March to November. My cousin in Boulder still calls me at what he thinks is 9am every Saturday – forgetting it's actually 8am in Phoenix. Doesn't he know I need my beauty sleep?
Real-World Impact You Need to Know
Let's talk practical stuff – the things that actually mess up your plans if you don't understand Arizona time:
- Flight schedules: Airlines display local times. Flying from Phoenix to Denver in summer? Your ticket might show departure at 10am MST and arrival at 12pm MDT. Same actual flight time, but looks different.
- TV broadcasts: Primetime shows air at 7pm AZ time year-round. But during DST months, that means Eastern Time shows air "live" at 10pm ET instead of 9pm. Took me three Mondays to figure out why The Bachelor was spoiled online before I'd seen it.
- Business hours: Calling clients in New York at 9am AZ time? That's noon in NYC – right when they go to lunch. I schedule all my East Coast calls before 7am Phoenix time now.
- Road trips: Driving from Vegas to Phoenix in March? You gain an hour entering Arizona. Driving back? Lose an hour. Your phone might auto-adjust, but your stomach clock won't.
Travelers Beware: Airport Edition
Phoenix Sky Harbor Airport has permanent signs reminding passengers: "Arizona does not observe Daylight Saving Time." Still, I see panicked travelers sprinting to gates weekly. Pro tip: If connecting through Phoenix, check your airline app for LOCAL departure times. Better yet, screenshot it.
Why Your Tech Devices Get Confused
Ever notice your phone displays the wrong time when you land in Phoenix? Most devices use location-based time settings. But Arizona's lack of DST combined with Navajo Nation exceptions creates perfect storms of confusion. Here's how to avoid trouble:
iPhone users: Go to Settings > General > Date & Time. Toggle "Set Automatically" OFF if you're traveling between Navajo and non-Navajo areas. Trust me – my calendar triple-booked me last business trip through Tuba City.
Windows PCs: Navigate to Settings > Time & Language > Region. Add Phoenix as an additional clock if collaborating with Arizona colleagues. Lifesaver for remote workers.
Smart watches: These are the worst offenders. My Fitbit insisted it was 4pm in Sedona when it was clearly 3pm. Had to factory reset before sunset hike timing worked properly. Such a hassle!
Your Burning Questions Answered
Q: Is Phoenix on Pacific time during summer?
A: Effectively yes, but technically no. From March to November, Phoenix (MST) matches Pacific Daylight Time (PDT) at UTC-7. But technically it's still Mountain Standard Time.
Q: What time zone is the Grand Canyon in?
A: Depends which part! South Rim follows Arizona no-DST (MST year-round). North Rim? That's in Utah technically, so it observes DST on Mountain Daylight Time (MDT) in summer. Check your tour confirmation times carefully.
Q: How does this affect Arizona sports games?
A: Massive impact! Cardinals games always list Arizona time. During fall NFL season, 1pm East Coast games start at 10am in Phoenix. Baseball's trickier - I once showed up at Chase Field an hour early for a Dodgers game because MLB.com displayed LA time.
Q: Do any other US states do this?
A: Hawaii also skips DST. Parts of Indiana used to opt out too. But Arizona's situation is unique due to the Navajo Nation exception. Honestly, it's more complicated than tax code.
Q: How do I handle international calls with Arizona businesses?
A: Always specify UTC offset: "Let's meet at 3pm Arizona time (UTC-7)" or "2pm MST" regardless of season. Avoid saying "Mountain Time" which implies possible DST. Saved countless client relationships this way.
Historical Head-Scratchers
Arizona hasn't always been consistent about this. During WWII, the entire state observed year-round DST like the rest of the country. Then from 1944-1967, different counties could choose whether to observe DST. Imagine driving from Yuma to Nogales and changing time zones five times!
The current law (ARS § 1-242) cemented the no-DST stance in 1968... mostly. Small towns near Nevada borders have occasionally held local votes to switch. Nothing ever passes though – we Arizonans hate changing clocks more than we hate humidity.

- Flight Tracker Hack: Add "MST" or "no DST" to your airport code searches (e.g., "PHX MST arrival")
My personal trick? I keep a cheap analog clock in my office set to Arizona time year-round with a label "NO DST EVER". Visitors think it's quirky until they miss their flight connection.
The Bottom Line: When someone asks what is the time zone of Arizona, the complete answer is "MST year-round except in Navajo Nation during DST months, resulting in seasonal alignment with Pacific time despite being geographically in Mountain time, causing endless confusion for travelers and tech devices alike."

Living With Arizona Time
After 15 years here, I've embraced the chaos. Summer evenings feel luxurious when you realize California folks are eating dinner in the same daylight. Winter mornings? Dark until 7:30am – brutal when scraping frost off your windshield.
Does it drive me nuts sometimes? Absolutely. I curse our time zone every spring when TV schedules shift. But secretly? I love not changing clocks. That extra hour of sleep in November when the rest of the country loses it? Priceless.
So next time you're wondering about the time zone situation in Arizona, remember: we're not wrong, we're just different. Set your watch to MST, disable DST auto-updates, and for heaven's sake – double-check those Navajo Nation border crossings!
