Is AZ MST or PST?

Time Zone. Arizona is on Mountain Standard Time . Arizona does not observe Daylight Savings, with the exception of the Navajo Nation. Arizona previously observed Daylight Savings beginning in 1918, but made the permanent change to Standard time in 1968.

Yes, Arizona can have two time zones depending on the period of the year: The Mountain Standard Time (MST) used by most of the state, and the Daylight Saving Time (DST) used by the Navajo Nation inside of Arizona.

great to know, thanks! > (or Eastern Standard Time) is 3 hours ahead of Arizona. Just for the record, that's actually Eastern Daylight Time. EST is what most of the rest of the western Atlantic coast follows year-round (GMT-5).

March 13, 2022, marks the start of Daylight Saving Time for most of the United States. But unlike almost everywhere else, Arizona doesn't observe Daylight Saving Time DST, and hasn't done so for about the last 40 years.

Since California (CA) and Arizona (AZ) currently have equivalent time zones, you can call someone during your normal hours and it will be the same time in Arizona as it is in California. Remember to check daylight savings for any time changes if you are scheduling a call.

Arizona was granted an exception to Daylight Saving Time in the late 1900s due to the extreme heat our state experiences. If the Grand Canyon State were to "spring forward," the sun wouldn't set until 9 p.m. during the summer. This would impede nighttime activities as well as push back bedtime for children.

Because of Arizona's hot climate, DST is largely considered unnecessary. The argument against extending the daylight hours into the evening is that people prefer to do their activities in the cooler evening temperatures.

Because the ground doesn't freeze in Phoenix, you only have to dig 18 inches below the surface to pour concrete footing for a house. If you want a basement, you'll have to go out of your way to dig deeper. That's complicated by a common soil phenomena in the state called caliche.

The low humidity in Phoenix means there are fewer clouds in the air to shield the land and absorb the heat, and the rocky terrain radiates the heat from the ground. To put it simply, the heat comes at us from all angles, which explains why Phoenix air conditioning is a must!

Due to Hawaii's location, there are fewer variations between winter and summer daylight hours, so it makes sense to not have daylight savings time in this state. Hawaii and Arizona are the only two states in the U.S. that do not observe daylight savings time.

Arizona, Hawaii and the U.S. territories that don't observe daylight saving time could choose whether to stick with their current time or move to daylight time.

The only parts of the US that do not have Daylight Saving Time are Hawaii, most of Arizona, Puerto Rico, the US Virgin Islands, Northern Mariana Islands, Guam, and American Samoa. Arizona experimented with the change beginning in 1918, but decided to permanently opt out of the Daylight Saving Time in 1968.

The U.S. Department of Transportation is responsible for overseeing DST and the country's time zones. All states but Hawaii and Arizona (except the Navajo Nation) observe DST. The territories of American Samoa, Guam, the Northern Mariana Islands, Puerto Rico and the U.S. Virgin Islands also do not observe DST.

Unlike most of the United States, Arizona does not observe daylight saving time (DST), with the exception of the Navajo Nation, which does observe DST. The Hopi Reservation, which is not part of the Navajo Nation but is geographically surrounded by it, also does not observe DST.

The idea is that in the summer months, we shift the number of daylight hours we get into the evening. So if the sun sets at 8 pm instead of 7 pm, we'd presumably spend less time with the lights on in our homes at night, saving electricity.

I speak, of course, of Democratic president Woodrow Wilson, who signed our nation's first law mandating Daylight Savings Time, the Standard Time Act, in 1918.
