Ever tried calling a friend in Arizona during the summer, only to realize you’re three hours ahead instead of two? It’s a classic. Everyone else is "springing forward" or "falling back," while Phoenix just... sits there.
Right now, if you're asking what time is it in Phoenix, the answer is pretty straightforward: it is Mountain Standard Time (MST). But there is a huge catch. Phoenix doesn't do Daylight Saving Time. While the rest of the country is busy fumbling with microwave clocks twice a year, Phoenix stays exactly where it is.
The Mystery of Arizona Time Explained
Honestly, it feels like a glitch in the matrix the first time you deal with it. From March to November, Phoenix is essentially on the same time as Los Angeles (Pacific Daylight Time). Then, once the clocks revert in the fall, Phoenix suddenly aligns with Denver (Mountain Standard Time).
You’ve basically got a city that changes its relationship with the rest of the world without actually changing its own clock.
Why? Because it’s hot.
Seriously, that is the primary reason. Back in 1967, the Arizona legislature took one look at the Uniform Time Act and said, "No thanks." If they shifted the clocks forward in the summer, the sun wouldn't set until nearly 9:00 PM. In a place where July temperatures regularly cruise past 110 degrees, nobody wants an extra hour of blistering sunlight in the evening.
Does Phoenix ever change?
Short answer: No.
Long answer: Still no, but your phone might make you think otherwise if you aren't careful.
If you are currently in Phoenix, your clock is at UTC-7. It stays at UTC-7 in January. It stays at UTC-7 in July.
What Time Is It In Phoenix Compared to You?
Since Phoenix is the "constant" and everyone else is the "variable," calculating the time difference depends entirely on the month. This is where people usually get tripped up.

- New York / East Coast: During the winter, Phoenix is 2 hours behind. In the summer? It’s 3 hours behind.
- Chicago / Midwest: Winter is 1 hour behind; Summer is 2 hours behind.
- Los Angeles / West Coast: In the winter, Phoenix is 1 hour ahead. In the summer, Phoenix is on the exact same time as LA.
It’s a bit of a headache for business meetings. I’ve seen people miss Zoom calls for years because they assumed "Mountain Time" always meant the same thing. In Phoenix, "Mountain Time" specifically means Mountain Standard Time all year long.
The Navajo Nation Exception
Wait, there’s a weird exception you should know about. If you drive north out of Phoenix toward the Grand Canyon and keep going northeast into the Navajo Nation, the time changes.
The Navajo Nation does observe Daylight Saving Time.
Why? Because their territory spans into New Mexico and Utah, and they wanted to keep their whole nation on one consistent schedule. But—and it gets weirder—the Hopi Reservation is inside the Navajo Nation, and they don't observe Daylight Saving.
If you’re driving through that part of Arizona in the summer, your car’s GPS will lose its mind. You can literally change time zones four times in an hour just by driving down the highway.
Why Phoenix Won't Ever "Spring Forward"
There’s a lot of talk lately about making Daylight Saving Time permanent across the U.S. (the Sunshine Protection Act). Even if that passes, Phoenix is likely to stay right where it is.
The energy costs are the main driver. A study by Arizona State University researchers, including experts like history professor Calvin Schermerhorn, has pointed out that an extra hour of evening sun would send air conditioning bills through the roof. When the sun is a literal hazard, you don't want more of it.
Summary of the Phoenix Time Situation:
- Current Zone: Mountain Standard Time (MST).
- UTC Offset: Always -7.
- DST Status: Never observed.
- Summer Sync: Matches Pacific Daylight Time (PDT).
- Winter Sync: Matches Mountain Standard Time (MST).
What You Should Do Next
If you're planning a trip or a meeting, don't just search "what time is it in Phoenix" and call it a day. Check the date.
If you’re visiting in the summer, prepare for the "Pacific Time" mindset. If you're coming in the winter, think "Mountain Time." And if you're heading to the Navajo Nation, just give up and wear two watches.
The best way to stay sane is to set your digital calendar specifically to "Phoenix Time" rather than just "Mountain Time." Most modern operating systems have a specific "Arizona" or "Phoenix" toggle that ignores the Daylight Saving jumps. Use it. It’ll save you from showing up an hour early—or late—to your next desert adventure.
