Right now, if you’re looking for tempe arizona time now, you’re probably either planning a meeting, catching a flight, or trying to figure out why your calendar invite looks "off."
It’s currently Mountain Standard Time (MST) in Tempe.
But here’s the kicker: Tempe—and pretty much all of Arizona—is a rebel. While the rest of the country is busy "springing forward" or "falling back" like clockwork, Tempe just stays put. Honestly, it’s one of the most confusing things for travelers, but for locals, it’s a point of pride. We don't touch our clocks. Ever.

The Mystery of the Shifting Time Zone
If you’re looking at a map, Arizona is technically in the Mountain Time Zone. But because we don't observe Daylight Saving Time (DST), our relationship with our neighbors changes twice a year.
It’s kinda like being in a long-distance relationship where only one person moves.
From March to November, when most of the U.S. is on Daylight Saving Time, Tempe actually has the exact same time as Los Angeles and Las Vegas. We’re basically on "Pacific Time" without actually being in the Pacific Time Zone. Then, in November, when everyone else "falls back," we suddenly realign with Denver and Salt Lake City.
We stay at UTC-7 all year long.

Why do we do this? It's not just to be difficult. Back in the 1960s, the state tried DST for one year and realized it was a total nightmare. Imagine living in a desert where the sun is already trying to kill you. Now imagine "saving" an extra hour of that scorching afternoon sun so it stays light until 9:00 PM.
No thanks.
By staying on Standard Time, we get sunset an hour earlier in the summer. That means the air conditioning can finally catch a break, and kids can actually go outside to play before it's their bedtime. It’s basically a massive energy-saving hack that keeps our power grid from melting down when it’s 115°F outside.
Tempe Arizona Time Now: The Navajo Nation Exception
Wait, it gets weirder.
If you’re just staying in Tempe, you’re fine. But if you decide to take a road trip from Tempe up to the Grand Canyon or Monument Valley, you might run into the "time warp."
The Navajo Nation, which covers a huge chunk of northeastern Arizona, does observe Daylight Saving Time. They do this because their land spans across Arizona, New Mexico, and Utah, and they wanted to keep their government offices on the same schedule.
But then—I'm not making this up—the Hopi Nation, which is entirely surrounded by the Navajo Nation, does not observe DST.

If you drive through that area in the summer, your phone's clock will literally jump back and forth an hour as you cross tribal borders. If you’ve got a tour booked at Antelope Canyon or a dinner reservation in Window Rock, you better double-check which "Arizona time" they’re using.
Quick Cheat Sheet for Tempe Time:
- Summer (March–Nov): Same as Los Angeles (PDT).
- Winter (Nov–March): Same as Denver (MST).
- Always: UTC-7.
Don't Let Your Phone Lie to You
Most modern smartphones are smart enough to handle the tempe arizona time now calculation, but they occasionally glitch if you’re near a border or using a VPN.
I’ve seen plenty of business travelers show up an hour early for a meeting at Arizona State University because their Outlook calendar thought Arizona followed the same rules as Colorado.
The safest bet?
If you’re scheduling something with someone in Tempe, don't just say "7:00 PM Mountain Time." That is a trap. Always specify "7:00 PM Arizona Time" or "7:00 PM MST." Most people outside the state don't realize that "Mountain Time" is a broad term that includes both Standard and Daylight versions, but Tempe only uses the Standard one.
Practical Steps to Stay on Track
Living or working in Tempe means you become a default expert in mental math. You're constantly adding or subtracting hours depending on the month.
If you want to stay sane while dealing with the time here, follow these simple steps:
- Manual Override: If you're visiting Tempe from a DST state, manually set your phone’s time zone to "Phoenix" rather than letting it "Set Automatically." This prevents it from hopping to a nearby cell tower in a different zone.
- The "California Rule": Remember that from March to November, Tempe is California time. It’s the easiest way to keep it straight in your head.
- Check the Sun: Remember that in the dead of summer, the sun rises around 5:30 AM in Tempe. If you’re planning a hike at "A" Mountain (Hayden Butte), you want to be done by 8:00 AM at the latest. The "time" might say it's early, but the desert heat doesn't care about the clock.
- Calendar Invites: Always use the "GMT-07:00 Arizona" time zone setting in Google Calendar or Outlook. This ensures the invite shifts correctly for your recipients in other states when their clocks change, while your time remains static.
Basically, Tempe time is simple because it never changes, which ironically makes it complicated for everyone else. Just keep your eyes on the "Arizona" setting and you'll never be late for a sunset at Tempe Town Lake.
