If you just landed at Sky Harbor and your phone is doing that weird glitchy thing where it can’t decide if it’s 2:00 PM or 3:00 PM, welcome to the club. Dealing with the Phoenix AZ time right now is basically a rite of passage for anyone visiting the Valley of the Sun. Most of the United States plays this biannual game of musical chairs with their clocks, but Arizona? We collectively decided in the late sixties that we were done with that.
Right now, Phoenix is on Mountain Standard Time (MST). It stays on MST every single day of the year. While your friends in New York or Chicago are "springing forward" and losing sleep, Arizonans are just vibing, keeping our clocks exactly where they are. It’s one of those quirks that makes this state fiercely independent, but it also makes scheduling a Zoom call with your East Coast boss a total nightmare half the year.
The "One Hour" Rule That Isn't a Rule
The biggest misconception about the time in Phoenix is that we’re always "one hour behind Denver" or "the same as Los Angeles." Both are true, but only sometimes. Because Arizona doesn’t observe Daylight Saving Time (DST), our relationship with the rest of the country shifts like sand in a monsoon.
From roughly March to November, when the rest of the US is "saving" daylight, Phoenix has the exact same time as Los Angeles (Pacific Daylight Time). During the winter months—from November to March—we align perfectly with Denver (Mountain Standard Time). Basically, we are the stabilizers. We don't move; the rest of the world moves around us.
Why the Heck Don't We Change?
You might think it’s just laziness, but it’s actually about survival and your electric bill. Back in 1967, Arizona actually tried out Daylight Saving Time for one summer. It was a disaster.

Think about it: Phoenix in July is a furnace. If we pushed the clocks forward, the sun wouldn't set until nearly 9:00 PM. That means an extra hour of blistering, 110-degree heat while people are trying to get home from work or put their kids to bed. It meant air conditioners had to crank for an extra hour during the hottest part of the day. The state legislature looked at the energy costs and the general misery of the population and said, "Yeah, no thanks."
Governor Jack Williams signed the bill to opt-out in 1968, and we’ve been the "Standard Time" holdout ever since. Honestly, it’s a flex. While everyone else is groggy for a week in March, we’re just enjoying our early morning hikes before the sun turns the trail into a skillet.
The Navajo Nation Exception
Now, if you’re planning a road trip up north to the Grand Canyon or Antelope Canyon, things get weird. The Navajo Nation, which covers a massive chunk of Northeastern Arizona, does observe Daylight Saving Time.
Why? Because the reservation extends into Utah and New Mexico, and they wanted to keep their entire nation on the same schedule. But wait—it gets better. The Hopi Reservation is completely surrounded by the Navajo Nation, and the Hopi do not observe DST.

If you drive from Phoenix to Window Rock in the summer:
- You start in Phoenix (MST).
- You enter the Navajo Nation and suddenly you’re an hour ahead.
- You drive into the Hopi partition and you’re back an hour.
- You leave the Hopi area back into Navajo land and you "gain" an hour again.
It is the only place in America where you can effectively time travel four times in a single afternoon just by crossing a street. If you’re booking a tour at Lower Antelope Canyon, always—and I mean always—double-check if the tour operator is using "Arizona Time" or "Navajo Time." Missing your slot because of a phantom hour is a very common, very sad tourist mistake.
Living the MST Life: Practical Tips
If you’ve just moved here or you’re just visiting, the Phoenix AZ time right now will mess with your head for at least a week. Here’s how to actually manage it without losing your mind.
Check the "Pacific vs Mountain" status
If you are doing business with people in California, remember that in the summer, you are on the same time. No math needed. In the winter, you are one hour ahead of them.

The Eastern Time Gap
This is the one that gets people. In the winter, Phoenix is only 2 hours behind New York. In the summer, we are 3 hours behind. If you have a 9:00 AM meeting on Wall Street, you’re waking up at 6:00 AM in the winter, but 5:00 AM in the summer. It’s brutal.
Automated Clocks
Your iPhone and Android are usually smart enough to handle this, but occasionally they get confused near the borders or if your "set automatically" toggle is acting up. Always ensure your time zone is set to "Phoenix" specifically, rather than just "Mountain Time." If you select "Mountain Time," your phone might try to "spring forward" with Denver, and you’ll show up to brunch an hour early like a weirdo.
Why This Matters for Your Health
There’s actually some science backing up Arizona’s stubbornness. Studies by experts like those at the American Academy of Sleep Medicine suggest that the "spring forward" jump causes a spike in heart attacks and traffic accidents due to sleep deprivation. By staying on Standard Time year-round, Arizonans avoid that annual shock to the system.
Sure, we don't get those 9:00 PM sunsets in the summer, but honestly, nobody in Phoenix wants to be outside at 9:00 PM in July anyway. We prefer our light in the morning when it’s a relatively "cool" 85 degrees.
Actionable Next Steps for Travelers
- Sync Your Calendar: If you use Google Calendar, go into settings and set your "Primary Time Zone" to (GMT-07:00) Arizona Time. This prevents the "ghost shift" of appointments when you cross state lines.
- Confirm Tours: If you're heading to Page, AZ or the Navajo Nation, call your guide 24 hours ahead and ask: "Are you operating on Phoenix time or DST?"
- The Sunset Rule: If you’re trying to catch a sunset at Camelback Mountain, don’t rely on your "hometown" logic. Check a local Phoenix weather app. In the dead of summer, the sun usually drops around 7:40 PM.
- Watch the Borders: If you're driving to Las Vegas or Los Angeles in the winter, remember you will gain an hour as soon as you cross the Colorado River.
The Phoenix AZ time right now is more than just a number on a clock; it's a reflection of a state that values its own comfort and energy grid over national conformity. It’s a bit confusing, sure, but once you get used to never having to change your microwave clock, you'll wonder why everyone else hasn't caught on yet.
