The Navajo Nation Observes Daylight Saving Time
Arizona famously skips daylight saving time — but not all of it does. The Navajo Nation, which covers much of northeastern Arizona, observes DST like most of the country. From mid-March to early November, clocks on Navajo land in Arizona run one hour ahead of the rest of the state.
Why: One Nation, Three States
The Navajo Nation is the largest reservation in the United States, spanning parts of Arizona, New Mexico, and Utah. New Mexico and Utah both observe daylight saving time. If the Arizona portion followed state practice, the Nation would be split into two different times for most of the year — the same community, school district, or chapter house could sit an hour apart from the next one over. Observing DST keeps a single, uniform time across the entire Nation.
The Hopi Exception Inside the Exception
It gets better. The Hopi Reservation is completely surrounded by the Navajo Nation — and it follows Arizona practice, ignoring DST. There is even a piece of Navajo land (the Jeddito enclave) inside the Hopi Reservation, which is inside the Navajo Nation, which is inside Arizona.
The result, during DST months, is a genuine geographic oddity: driving a stretch of highway in northeastern Arizona, you can cross between Navajo and Hopi land and change the clock time several times in under two hours of driving without ever leaving the state.
What Time Is It Where, Right Now?
| Area | Mid-March – early Nov | Early Nov – mid-March |
|---|---|---|
| Arizona (most of the state) | MST (UTC−7) | MST (UTC−7) |
| Navajo Nation (incl. its Arizona portion) | MDT (UTC−6) — 1 hour ahead | MST (UTC−7) — same |
| Hopi Reservation | MST (UTC−7) — matches Arizona | MST (UTC−7) |
In winter, everything lines up: the whole state, Navajo Nation included, reads the same clock. The split only exists while daylight saving time is in effect elsewhere.
Practical Tips for Visitors
- Phone clocks near boundary areas can jump back and forth as they pick up towers on either side — don't trust an auto-updating phone for a tour departure time.
- Tour operators at places like Monument Valley (Navajo) typically run on Navajo time (MDT in summer); Antelope Canyon tours near Page often state times explicitly in both. Confirm which clock a reservation uses.
- When in doubt, ask "is that Navajo time or Arizona time?" — locals are used to the question.
For the state outside the Navajo Nation, the live clock on our home page is always correct.
