Talk:Time in Arizona

Phoenix, AZ -July 4, 2022 is on Pacific Time

Suggest some editing on this information. The beginning states that "All of AZ is on MT TIME" therefore, misleading and reading further the article gives reference to Phnx/Albq but as of today, July 4, 2022, Phoenix is on Pacific Time. The graph chart should reflect this, as well as many maps I see on the Web that are incorrect and show nothing about an entire hour's difference. No wonder some are confused. I've checked many reliable sites. Oddly they begin "All of Arizona is on Mt.Time" and should state "Parts of AZ are on Pacific Time," right at the beginning. Most people will not read further to finally happen upon any exceptions, if they are noted correctly. There is a lot of reference to the Navajo Nation time observance and oddly again, this is on the Northeastern side of the State. Just a suggestion for clarity that "All" will clearly see that; "No, not all of Arizona is on Mountain Time through the entire year." There's some large chunks missing for the West side of Arizona.

I agree. With the exceptions of Navajo Nation observing UTC-6 while Denver is currently in MDT, AZ is operating in UTC-7 just as the Pacific is that's why it's the same local time in Phoenix as it is in Seattle right now. So we have created 2 states, co-existing and currently operating on MTS labeled as "mountanous" but physically observing UTC-7 "Pacific" time. PDT = MST = MPST = UTC-7 = OR, WA CA BC Baja Peninsula Mazatlan

MDT = UTC-6 = Mexico City, Durango, most of Mexico (different time zone so there is an hour difference)

If AZ and the coastal regions of Mexico don't change to a Pacific suffix and remain considered mountainous, international planning and even locals may not notice the change or conversion of MST vs MDT which currently coincide simultaneously like never before.

This matters because the Sunshine Act just passed approval from the Senate and states we all remain on daylight, no more clock changes and no more rogue states being required to stop on standard time due to 1966 law. Therefore, MTS must be converted namewise to be in alignment with Pacific. Otherwise, the ancient predicted time of Mazatlan's upcoming total solar eclipse will continue to be falsely advertised in UTC-6 time and not as locally observed UTC-7 with totality peaking at 11:07am not noon like the rest of Mexico. 173.241.161.229 (talk) 02:44, 12 May 2023 (UTC)

This article is nothing but misleading.

Arizona observes two time zones, this article and all subsequent comments are trying to indicate that it only acknowledges one time zone. It needs to be deleted. 2600:1011:B32F:5C05:231D:B9D:CB63:EA39 (talk) 11:38, 26 May 2025 (UTC)

Technically Accurate but Practically Misleading

I agree with the concerns raised above. The lead is technically accurate but practically misleading. Here's a concrete proposed revision:

Current lead:

All of Arizona is in the Mountain Time Zone. Since 1968, most of the state—except the Navajo Nation—does not observe daylight saving time and remains on Mountain Standard Time (MST) all year.

Proposed revision:

All of Arizona is in the Mountain Time Zone. Since 1968, most of the state—with the exception of the Navajo Nation—has not observed daylight saving time. In practice, this means most of Arizona is on the same time as California from March to November, and the same time as Utah and New Mexico from November to March.

This keeps the technical accuracy while immediately clarifying the practical effect for readers. As a 25-year Arizona resident, I can confirm this matches how locals actually describe it. ~~~~ Zelray (talk) 03:30, 18 February 2026 (UTC)

Hi Zelray: what you quote as "Current lead" is only one sentence of the lead. The complete lead of the article currently reads as below (bolding, wikilinks, and references have not been preserved in the pasted text here). Dmoore5556 (talk) 04:02, 18 February 2026 (UTC)

[begin]

Time in Arizona, as in all U.S. states, is regulated by the United States Department of Transportation as well as by state and tribal law.

All of Arizona is in the Mountain Time Zone. Since 1968, most of the state—except the Navajo Nation—does not observe daylight saving time and remains on Mountain Standard Time (MST) all year. This results in most of Arizona having the same time as neighboring California each year from March to November, when locations in the Pacific Time Zone observe daylight saving time. From November to March, clocks across the state match those in neighboring Utah and New Mexico.
