Time is weird here. In most of America, you "spring forward" or "fall back" like clockwork, but if you’re looking at the az time zone right now, you’ll notice we just don’t play that game.
It’s currently January 2026. While my friends in New York are shivering through early sunsets and my family in Colorado is strictly on Mountain Standard Time, Arizona is doing its own thing. Well, mostly.
Honestly, the biggest mistake people make is assuming the whole state follows the same rule. It doesn't. If you’re driving through the high desert or planning a meeting with a Phoenix-based team, you’ve got to understand the "donut" effect.
The Reality of AZ Time Zone Right Now
Arizona is officially on Mountain Standard Time (MST). We are UTC-7.
Right now, in the dead of winter, we are perfectly synced up with Denver and Salt Lake City. But come March? Everything changes. While the rest of the country pushes their clocks forward to chase the sun, Arizona stays put. We don't want more sun. We have plenty.
Think about it. When it’s 115 degrees in July, the last thing any sane person wants is the sun hanging around until 9:00 PM. That extra hour of "daylight" is basically just an extra hour of expensive air conditioning and misery.

Why We Quit the Clock Changing Game
We actually tried Daylight Saving Time (DST) back in 1967. It lasted exactly one summer.
The outcry was pretty much immediate. Parents hated that their kids were trying to go to sleep while the sun was still blazing. Drive-in movie theaters (which were a huge deal back then) couldn't start their first show until nearly 10:00 PM.
By 1968, the Arizona Legislature basically said "no thanks" and passed a law to stay on Standard Time year-round. We’ve been the rebels of the time world ever since, alongside Hawaii.
The Navajo Nation "Donut" Exception
This is where it gets kind of trippy. If you’re traveling through Northeastern Arizona, your phone clock is going to have a mid-life crisis.
The Navajo Nation does observe Daylight Saving Time. Why? Because their land stretches into New Mexico and Utah, and they wanted to keep their entire nation on the same schedule.

- Arizona State: No DST (MST all year).
- Navajo Nation: Uses DST (Switches to MDT in summer).
- Hopi Reservation: No DST (They are inside the Navajo Nation but follow Arizona state rules).
If you drive from Flagstaff to Window Rock in the summer, you'll jump forward an hour. If you then drive into the Hopi village of Kykotsmovi, you jump back an hour. You can literally cross six time zone boundaries in a single afternoon without ever leaving the state.
How It Affects Your Connections
If you're doing business or calling home, the az time zone right now means we are two hours behind the East Coast (EST) and one hour ahead of the West Coast (PST).
But write this down: From March to November, we effectively become the West Coast.
When California "springs forward" into Pacific Daylight Time, they land exactly on our time. For those eight months, Phoenix and Los Angeles are twins. It makes scheduling a lot easier for half the year, but it leads to a lot of "wait, are you an hour ahead of me or not?" texts in the spring.
Does it actually save energy?
The original logic for DST was to save fuel and electricity. In Arizona, researchers have found the opposite is true.

A famous study out of Indiana (which used to have similar time quirks) suggested that having more sunlight in the evening actually increases energy use because people run their AC harder to combat the heat of the late afternoon sun.
In Phoenix, where the pavement stays hot long after dark, that extra hour of sun is a literal budget killer.
Practical Steps for Travelers and Professionals
Don't trust your "automatic" clock settings if you are near the border of the Navajo Nation. Manually lock your phone to "Phoenix" time if you have a tour scheduled in Page or Lower Antelope Canyon.
Most tour operators in Page (which is technically outside the Navajo Nation) stay on Arizona time, but some guides might use Navajo time. Always ask: "Is this Phoenix time or Navajo time?" when you book.
If you are scheduling a Zoom call for late March, remember that while you stay the same, the person on the other end is moving.
Check these specific things before your next AZ trip:
- Confirm the location: Are you in a Tribal area or state land?
- Sync your calendar: Use "Phoenix" as the time zone, not "Mountain Time," or your calendar might shift your appointments by an hour when the seasons change.
- Check the sun: Even without the clock change, our winter days are short. Sunset in January is usually around 5:45 PM.
Lock in your meeting times using a tool like WorldTimeBuddy, but specifically select "Phoenix" to avoid the MST/MDT confusion. If you're visiting the Grand Canyon, you're on Arizona time. If you're heading to Monument Valley, you're likely on Navajo time. Double-check your reservations now to avoid showing up an hour late to the best sunrise of your life.
