So, you’re looking for flagstaff time right now.
If you just want the quick answer: Flagstaff is on Mountain Standard Time (MST).
Because Arizona (mostly) refuses to touch its clocks, Flagstaff stays at UTC-7 year-round. While the rest of the country is busy "springing forward" or "falling back" and feeling like they’ve been hit by a truck, Flagstaff just... sits there. It's consistent. It's stubborn. Honestly, it's kinda great once you get used to it.
The Weirdness of Arizona Time
Most people assume that if you're in the mountains, you're on Mountain Time. You are, but there’s a catch.
Since Flagstaff doesn't observe Daylight Saving Time (DST), its relationship with other cities changes twice a year. In the winter, Flagstaff matches Denver. They're both MST. But come March, when Denver jumps ahead to Mountain Daylight Time (MDT), Flagstaff stays put.
Suddenly, Flagstaff has the same time as Los Angeles.
Think about that. You can drive from the high pines of Flagstaff to the beaches of Santa Monica in the summer and never have to change your watch. But if you drive east into New Mexico, you'll lose an hour the second you cross the state line. It’s a logistical headache for anyone trying to schedule a Zoom call with someone on the East Coast.

Why Flagstaff Won't Change
Why does Arizona do this? It's not just to be difficult.
Back in the late 1960s, Arizona basically looked at the sun and said, "No thanks, we've had enough." The logic was simple: heat. In a state where the sun is trying to bake you alive for four months of the year, the last thing anyone wants is more "daylight" in the evening.
If Flagstaff used DST, the sun wouldn't set until nearly 9:00 PM in the summer.
While that sounds nice for a BBQ, it means the desert floor (and even the high-altitude volcanic soil in Flagstaff) stays hot much longer. It drives up energy costs. Air conditioners have to work harder. Parents can't get their kids to go to bed because it looks like mid-afternoon outside at 8:30 PM.
Navigating the Navajo Nation Exception
Now, if you think you've got it figured out, let's complicate things.
The Navajo Nation, which covers a massive chunk of northeastern Arizona (just a short drive from Flagstaff), does observe Daylight Saving Time. They want to be on the same time as their tribal lands in New Mexico and Utah.

But wait, there's more.
The Hopi Reservation is entirely surrounded by the Navajo Nation. And the Hopi? They follow Arizona's lead and don't use DST.
If you drive from Flagstaff to Tuba City and then into the heart of the reservation during the summer, you could theoretically change time zones six times in a single afternoon. It’s the only place in America where your GPS might actually have a nervous breakdown trying to tell you when you'll arrive for dinner.
Current Sun Cycles in the High Country
Right now in January 2026, the days are short but starting to stretch.
In Flagstaff, the sun is currently coming up around 7:34 AM and dipping behind the San Francisco Peaks around 5:38 PM. You get about 10 hours of daylight. Because of the 7,000-foot elevation, that sun is intense even when it’s 20 degrees outside.
If you're planning a hike at Buffalo Park or heading up to Snowbowl, you’ve gotta track these sunset times. Once the sun drops, the temperature in Flagstaff doesn't just fall—it plummets. It can go from a crisp 45 degrees to a bone-chilling 15 degrees in the span of an hour.

Practical Tips for Travelers
If you’re visiting, don’t trust your phone to always get it right immediately, especially if you’re near the reservation boundaries.
- Manual Override: If you have an important tour at the Grand Canyon or a dinner reservation in town, manually set your phone to "Phoenix" or "MST" time rather than "Set Automatically."
- The 2-Hour Gap: In the summer, remember that Flagstaff is 3 hours behind New York. In the winter, it’s only 2 hours behind.
- Check the Weather: Don't let the "sunny" part of "daylight" fool you. Flagstaff is one of the snowiest cities in the United States.
The Actionable Reality of Flagstaff Time
Understanding flagstaff time right now is really about understanding your location relative to the state's borders.
If you are currently in Flagstaff, you are on Mountain Standard Time. You are seven hours behind Coordinated Universal Time (UTC-7).
If you are trying to call someone in Flagstaff from Chicago or New York, double-check if it’s currently "Daylight" season (March through November). If it is, subtract an extra hour from what you usually expect.
The best thing you can do is sync your internal clock to the mountain rhythm. People in Flagstaff tend to start their days early to catch the light and wrap up when the mountain shadows get long. Whether you're here for the stars (it is the world's first International Dark Sky City, after all) or the snow, the clock is just a suggestion—the sun is the real boss.
Your next steps for staying on schedule:
- Check your device's time zone setting: Ensure it is set to "Arizona" or "Phoenix" rather than a generic "Mountain Time" setting that might trigger a DST shift.
- Confirm tour times: If you've booked a trip to Antelope Canyon or the Navajo Nation, call the operator to ask specifically if they are on "Navajo Time" or "Arizona Time."
- Plan for the "Temp Drop": Note the sunset time for today (approx. 5:38 PM) and ensure you are off the trails at least 30 minutes prior to avoid the rapid temperature cliff.
