Ever try to schedule a Zoom call with someone in Phoenix and end up sitting in an empty digital lobby for an hour? You’re not alone. It’s a classic move. One minute Arizona is on the same page as Denver, and the next, it’s basically a suburb of Los Angeles.
People ask what is time in phoenix like it’s a simple question with a single answer. Honestly, it's not.
The short answer is that Phoenix is always on Mountain Standard Time (MST). It never leaves. While the rest of the country is busy "springing forward" and "falling back," Arizona just stays put. This creates a weird seasonal dance where Phoenix matches Pacific Time in the summer and Mountain Time in the winter.
It’s confusing. It’s glorious. And if you live here, it’s a point of fierce desert pride.
The 1967 Rebellion: Why Phoenix Opted Out
Most people think Daylight Saving Time (DST) is some ancient law of nature. It isn't. In the U.S., it was largely standardized by the Uniform Time Act of 1966. Arizona tried it for exactly one year—1967—and the state basically collectively lost its mind.

Imagine it’s July in the Sonoran Desert. The sun is already a physical weight.
If Arizona followed DST, the sun wouldn’t set until nearly 9:00 PM. That sounds lovely in a place like Seattle or New York, but in Phoenix? That’s an extra hour of 110-degree heat baking the pavement while you’re trying to put your kids to bed. It means your air conditioner has to work an hour longer at peak capacity.
The state legislature looked at the mounting energy bills and the grumpy, heat-exhausted citizens and said, "No thanks." By 1968, they passed a law to stay on Standard Time year-round. They realized that in the desert, daylight isn't something you want to "save." You want it to go away so you can finally sit on your patio without melting.
The "Time Traveler" Reality of Living in Arizona
Because Phoenix doesn't move, everyone else moves around it. This is where the headache starts for business travelers and remote workers.
- From March to November: Most of the U.S. is on Daylight Saving Time. During this stretch, Phoenix is effectively on the same time as California (Pacific Daylight Time).
- From November to March: The rest of the country "falls back" to Standard Time. Suddenly, Phoenix is back in sync with its Mountain Time neighbors like Utah and Colorado.
It’s a bizarre seasonal shift. If you have a standing 9:00 AM meeting with a colleague in New York, that meeting will be at 6:00 AM for you in the summer, but 7:00 AM in the winter. You basically have to relearn your entire external schedule twice a year, even though your own wall clock hasn't budged.
The Navajo Nation Exception (The Donut Hole)
If you think the state-wide rule is tricky, wait until you drive north. Arizona actually has a "time donut."
The Navajo Nation, which covers a massive portion of Northeastern Arizona, does observe Daylight Saving Time. They do this because their reservation spans across Arizona, New Mexico, and Utah, and they wanted to keep their whole nation on one consistent time.
But wait, there's more.
The Hopi Reservation is located entirely inside the Navajo Nation. And the Hopi, following the rest of Arizona’s lead, do not observe DST.

If you drive across Northern Arizona on a summer day, you could theoretically change your watch six times in a couple of hours just by crossing tribal borders. It’s a logistical nightmare for local delivery drivers but a fun trivia fact for everyone else.
Why We Don't Just "Fix" It
Every few years, someone in the legislature suggests Arizona should just join the rest of the world. The argument is usually about "interstate commerce" or making it easier for people to watch live sports without doing math.
But the "what is time in phoenix" debate usually dies pretty quickly.
The environmental impact is a huge factor. A 2008 study by the Department of Energy actually looked at this, and while results vary by region, the consensus in Arizona is that extra evening sun leads to significantly higher cooling costs. In a state where the power grid is already pushed to the limit during July heatwaves, nobody wants to gamble with an extra hour of sun.
Plus, there’s the lifestyle factor. Arizonans live for "The Cool Down." That moment when the sun dips behind the White Tank Mountains and the temperature drops from "surface of the sun" to "actually pleasant" is sacred. Shifting that hour later would ruin the only time of day people can actually go for a run or walk the dog.
How to Handle Phoenix Time Like a Pro
If you’re visiting or doing business here, don't rely on your internal clock. It will betray you.
- Check the UTC Offset: Phoenix is always UTC-7. Always.
- Use "Arizona" as a Time Zone: When setting up calendar invites in Outlook or Google, don't just select "Mountain Time." Select the specific "Arizona" or "Phoenix" option. Most modern software is smart enough to know Arizona doesn't shift, but if you just click "Mountain," the software might accidentally bump your meeting by an hour in March.
- Confirm the Coast: If you're talking to someone in California during the summer, you’re on the same time. If it’s winter, you’re an hour ahead of them.
Honestly, the easiest way to manage what is time in phoenix is to just assume the rest of the world is wrong. We’re the ones staying consistent; everyone else is the one playing with their clocks.
For those moving here, give it a year. You’ll eventually experience that first Sunday in March when the news reports everyone else is losing an hour of sleep, and you’ll realize you get to sleep in. It’s a small, smug victory that makes the 115-degree August days just a little more bearable.
Immediate Practical Steps
Stop trying to memorize the offset. Instead, if you're coordinating with Phoenix:
- Set your world clock app to include "Phoenix" as a permanent city.
- Always verify "Standard" vs "Daylight" when booking flights; Phoenix Sky Harbor operates on MST year-round, which can lead to "missing" flights if your connecting city shifted and you didn't account for the change in the gap.
- When in doubt, use a site like TimeAndDate to see the current "live" offset before sending that calendar invite.
