Time in Arizona

Arizona is a state that spans two time zones. The state is divided by the Colorado River, which runs through the middle of the state. The eastern part of the state is in the Eastern timezone for Arizona, while the western part of the state is in the Pacific Time Zone. When is it in Arizona? The state of Arizona spans two time zones, so it is important to know which time zone you are in. The eastern part of the state is in the Eastern Time

Arizona is a beautiful state in the southwest of the United States. The state is known for its natural beauty and its many sunsets. It is also known as the Grand Canyon State. Arizona is also the sixth-largest state in the country.

Arizona is home to the Grand Canyon National Park, one of the Seven Natural Wonders of the World. The Grand Canyon is 277 miles long, up to 18 miles wide, and over a mile deep.  It’s 3:15 pm on a Wednesday in Arizona. If you’re in Connecticut, it’s 12:15 pm; in Tennessee, it’s 11:15 am. In Arizona, it’s 3:15 p.m.

History of Arizona Time Zone

The history of time zones in Arizona is fascinating due to the state’s unique approach to daylight saving time (DST). Here’s an overview:

Pre-Standard Time Zones

Before the standardization of time zones, timekeeping was a local matter, with towns setting their clocks based on the position of the sun or a well-regulated local clock. This system was chaotic for scheduling, particularly for railways.

Adoption of Standard Time Zones

In 1883, railway companies in the United States and Canada established standard time zones to streamline scheduling. The U.S. Congress formally adopted this system in 1918 with the Standard Time Act, which also incorporated daylight saving time.

Arizona and Daylight Saving Time

Arizona, situated in the Mountain Time Zone, initially participated in daylight saving time along with the rest of the country. However, due to Arizona’s hot climate, there was strong resistance to DST. The additional hour of daylight in the evening led to hotter temperatures when people were most active, which was particularly uncomfortable and costly in terms of air conditioning.

Exemption from DST

In 1968, Arizona was granted a federal exemption from daylight saving time, meaning the state would not advance clocks in the spring to begin DST. The Navajo Nation, which spans parts of Arizona, Utah, and New Mexico, decided to continue observing DST to maintain uniformity across its territory, despite the exemption.

Anomaly of the Navajo Nation and the Hopi Reservation

The Navajo Nation observes daylight saving time, making it an anomaly within Arizona. Conversely, the Hopi Reservation, which is surrounded by the Navajo Nation, does not observe DST, aligning with the rest of Arizona. This creates a unique situation where a short drive through these areas can involve multiple time changes.

Current Situation

As of my last update in April 2023, Arizona does not observe daylight saving time, except for the Navajo Nation. This means that for most of the state, the time zone is effectively Mountain Standard Time year-round. When the rest of the Mountain Time Zone moves their clocks forward for DST, Arizona is effectively on the same time as Pacific Daylight Time.

Legislative Attempts

There have been occasional legislative attempts to change Arizona’s approach to DST, either to adopt it statewide or to put the decision to a public vote. However, as of my last update, none of these efforts have been successful.

What Time Zone in Arizona?

Arizona is primarily in the Mountain Standard Time (MST) zone. However, it’s important to note that most of Arizona does not observe Daylight Saving Time (DST). This means that during DST, the state effectively operates at the same time as Pacific Daylight Time (PDT). The Navajo Nation, in the northeastern part of the state, does observe DST, aligning with the Mountain Daylight Time (MDT) during those months.

How Many AZ Time Zones Are There?

Arizona primarily adheres to Mountain Standard Time (MST) throughout the year, with no changes during different seasons. However, within Arizona, the Navajo Nation switches to Daylight Saving Time (DST), adopting Mountain Daylight Time (MDT) during this period.

It’s often mistakenly thought that Arizona shifts between Pacific Daylight Time (PDT) in the summer and Mountain Standard Time (MST) in winter. This confusion stems from the fact that MST and PDT both align with UTC-7, leading Arizona to share the same local time as California and Nevada during summer, even though Arizona remains on MST year-round.

Does Arizona have 2 time zones?

Yes, Arizona can be said to have two effective time zones.

The state is situated in the Mountain Standard Time (MST) zone. The majority of Arizona does not adhere to daylight saving time (DST). In contrast, the Navajo Nation in the northeast of the state observes DST. As a result, they switch to Mountain Daylight Time (MDT) from March to November, in line with DST.

Between November and March, during the non-DST months, the entire state of Arizona operates on Mountain Standard Time. However, with the onset of DST, the Navajo Nation moves one hour ahead of the rest of Arizona. This practice is due to the Navajo Nation’s territory extending into Utah and New Mexico, where DST is observed.

How are Time Zones Represented?

There are 24 time zones represented on Earth, each identified by a letter of the alphabet. The time zone in which you live is determined by your geographical location and the time within that zone. UTC, or Coordinated Universal Time, is the global time standard and is used to compare the time in different time zones.

UTC is not used for standard time in any one time zone but is instead used to establish the time for the world. For example, the time zone in which you live may be Eastern Standard Time in North America and Central European Time in Europe. You will receive an error message if you try to view content that includes UTC.

What is the Difference Between Standard Time and Daylight Saving Time?

Standard time is the time that is set by the government and daylight saving time is the time that is set by the government and moved one hour ahead during the summer.  The United States participates in daylight saving time.  The sun rises later in the summer and the sun rises earlier in the summer. To make it easier to go to work and come home from work the government moves the clock ahead one hour. 

The world has organized time zones, or time zones that are fifteen degrees apart or thirty minutes. If a person wishes to know what time it is when it is dark at home, and it is light at work they can look at a clock at work. It will show the local time, which is an hour later than the home time. The person then can add or subtract an hour to get the right time at the home or business. There are 24 hours in a day, so the answer is easy to calculate.

How Many Time Zones Are in the United States?

There are six time zones in the United States. They are Eastern, Central, Mountain, Pacific, Alaska, and Hawaii. The Eastern time zone is the most populous, and it covers the eastern part of the country. The Central time zone covers the central part of the country and it’s the second-most populous. time zone.

The Mountain time zone (or the Mountain standard time zone) covers the western part of the country, as well as parts of the northeastern part. The Pacific and Alaska time zones cover smaller areas. Puerto Rico also has a time zone. 

Conclusion: There are 24 time zones in the world. Arizona is in the Mountain Standard Time Zone. There are 11 time zones in the United States. For more information, visit RSLOnline.

Why does the Navajo Nation Follow Daylight-saving Time?

Although the Navajo Reservation near the Four Corners region does not have an official time zone, it has chosen to adhere to daylight-saving time like the rest of the country. (except the rest of Arizona and the state of Hawaii). The reservation area is large (over 27,400 square miles) and because parts of it reach into neighboring states that do observe daylight saving time, the decision was made in 1968 to stick to the time change.

What is even more interesting is that there are two different Native American reservations situated inside the Navajo Nation; The Hopi reservation is surrounded by the Navajo reservation, and they do not follow daylight-saving time. Sounds interesting, right? You can also read more like this here.

This means if you were to drive from one side of the Navajo reservation, through the Hopi reservation, and back into Navajo land within a 100-mile span, you would change time zones several times!

The Navajo Nation is a beautiful and sacred place where you can find the world-famous Monument Valley and the looming mountain formation known as Shiprock. There are also many charming small towns full of hospitable people.

Why does Arizona not follow Daylight-saving Time?

A bill was put forth in Arizona to keep the state’s clocks on the same time year-round. The argument for observing daylight-saving time is that it gives workers more light in the evenings and less light in the mornings through spring and summer.

Arizona’s legislature decided that since Arizona has more sunny days and daylight than other states, we don’t need an extra hour of sunlight in the hot summer months. Most Arizonans would agree; not having to change the clocks twice a year is a nice perk!

Most phones and cars can automatically change time zones, making road trips across state lines more convenient.

Is Arizona at the same time as California?

Arizona and California share the same time only part of the year:

During Standard Time: Arizona is in Mountain Standard Time (MST) and California is in Pacific Standard Time (PST), so Arizona is one hour ahead of California.

During Daylight Saving Time (DST): Most of Arizona does not observe DST and remains on MST, which is equivalent to Pacific Daylight Time (PDT). During this period, Arizona and California share the same time.

The exception is the Navajo Nation in northeastern Arizona, which does observe DST. During DST, this area is not at the same time as California.

Why does Arizona not have daylight savings?

Arizona chooses not to follow daylight saving time largely due to its unique climatic and geographical factors.

As explained on the Britannica website, in the summer, having an additional hour of sunlight in the evening would lead to extended periods of intense heat.

By not adhering to daylight saving time, Arizona also streamlines time management for its businesses, governmental bodies, and citizens.

Remember, daylight saving time is approaching, so most will set their clocks forward by an hour this weekend, except in certain states like Arizona.
