While most of the rest of the United States observes Daylight Saving Time (DST), Arizona does not. In March, most of the country will “spring forward” and set their clocks one hour earlier. In November, they “fall back” and reset the clocks to an hour later, gaining back the extra hour returning to Standard Time. Meanwhile Arizona stays on standard time all year long, inspiring the refrain: Spring remain, Fall the same. Arizona is in the Mountain Standard Time (MST) zone, also known as Mountain Time. Places in the Mountain Time zone who observe daylight saving time are referred to as Mountain Daylight Time (MDT).
When did this happen, and why?
How did we get here?
The idea of changing clocks to take advantage of more sunlight in the summer months is not new. Congress first adopted a measure in 1918 to extend the workday and conserve fuel needed for war industries during World War I. The same legislation established standard time zones (40 Stat 450 & 56 Stat 9). After the war, the nationwide mandate was repealed but DST continued as a local option. DST was implemented again as “War Time” during World War II. The nationwide mandate was repealed again in 1945. Once again state and local governments could choose to observe it. They had the additional authority to decide when would start and end. By 1966, there was a patchwork of local laws that caused confusion and inefficiencies for radio and TV stations, railways, airlines, and bus companies. And, presumably, anyone who wanted to know what time it was.
In 1966, Congress passed the Uniform Time Act, intended to “promote the adoption and observance of uniform time within the standard time zones”. It implemented a plan to adopt DST. It instructed all Americans to move their clocks forward one hour on the last Sunday of April and back one hour on the last Sunday of October of each year. The law allowed any state to exempt itself from the time changes, provided the exemption applied to the entire state.
Since 1966, standard time has shrunk to about 4 months as Congress has shifted the start of DST earlier and the start of standard time later. Currently, DST starts the second Sunday in March and ends the first Sunday in November.
In 1968, the Arizona Legislature exempted the state from the DST, choosing to remain on standard time throughout the year. Filed that same year was Senate Concurrent Resolution 2 proposing to refer the issue to the voters. Both measures passed the Senate and were transmitted to the House at about the same time. The House opted to proceed by passing a statute. Senate Bill 1 was approved in the Senate by a vote of 25 to 3 (PDF page 972) and in the House of Representatives 49 to 1 (PDF page 782), enough to pass with an emergency clause. It became effective upon the signature of Governor Jack Williams on March 21, 1968. You can read it at Arizona Revised Statutes §1-242. It has never been amended.
Not all areas inside the borders of Arizona shun DST. The Navajo Nation lies in northeastern Arizona, northwestern New Mexico, and southeastern Utah. The Navajo Nation is on DST, keeping the entire reservation on the same time. But it’s a little more complicated than that. The Hopi Nation, which is surrounded by Navajo land, is not on DST and therefore is on the same time as most of Arizona. Given that there is also a portion of the Navajo Nation that is surrounded by Hopi land, you may need a map to be able to tell what time it is during DST in northeastern Arizona.
Why did Arizona oppose DST? To Arizonans living in areas with intense heat, an extra hour of sunlight in the evening is not appealing. It would not spur people to go out and enjoy the longer evening hours that are beloved by Americans in summer-loving climates. In addition, in the Arizona desert observing DST is unlikely to meet the original goal of energy conservation. A few other areas have opted out of DST, including the State of Hawaii, Puerto Rico, Virgin Islands, Northern Mariana Islands, Guam, and American Samoa.
Is DST a good idea?
The original goal of DST was to shift the clocks forward during the months with the most sunlight to maximize use of natural light and save heating and transportation fuel. It’s not clear that DST meets that goal. Life and energy consumption have changed dramatically since 1966. Now, air conditioning is virtually everywhere, there are multiple TV sets and computers in a typical home, and most people who plan activities to enjoy the “bonus hour” use gasoline to get there. The savings were evaluated by the Department of Energy in a report to Congress in 2005 and by the Congressional Research Service in 2020.
Studies suggest that DST is not good for our health. Time changes disrupt our natural circadian rhythm. When clocks are set ahead in the spring, many people can’t fall asleep at night and feel more groggy in the morning. This can impair focus and judgment during the time it takes our bodies to adjust, resulting in lost productive time and car accidents. Some studies show a higher risk of heart attack following time changes, especially after the “spring forward” change that starts DST. Some people who suffer from mood disorders may experience an increase in depressive symptoms after the “fall back” change when daylight grows shorter.
And most people detest changing their clocks twice a year. A poll published in the Economist/YouGov in November 2021 found that 63% of respondents want to stay on the same time all year. Other polls found the number to be even higher: nearly 75% would prefer not to change their clocks. Twenty-eight state legislatures considered the issue in 2022. The National Conference of State Legislatures (NCSL) reports that some 450 bills and resolutions have been considered by state legislatures in the last 7 years.
If DST is eliminated, the choice is between permanent DST or permanent standard time. This is a major dispute. The Economist/YouGov poll found that 48% preferred permanent DST, while 29% favored permanent standard time. A different poll showed that 40% of respondents support permanent standard time, with 31% preferring permanent DST. Eighteen states have enacted measures to establish year-round DST as soon as federal law allows it. In general, businesses that benefit from longer business hours, such as retail, restaurants, and outdoor recreation advocate for permanent DST. For instance, longer daylight in the fall, when the days grow shorter, has been a boon for the candy and Halloween industries. The hurdle to this point of view is that states can opt out of DST, but don’t have the authority to set permanent DST without federal approval.
Others recommend permanent standard time. One factor is the health benefit of standard time. More light in the morning, for example, helps many to feel more alert and to maintain a healthful regular bedtime. There is evidence that altering the body’s relationship to the sun can negatively affect sleep, cardiac function, weight, and risk of cancer. Some of the business community agrees. The ski industry, for example, supports standard time year-round because it enables ski activities earlier in the day. Parents have long worried about DST in the fall, when schoolchildren go to school while it is still dark. And don’t forget us here in Arizona. We Arizonans love our sunshine, but most of us feel we can get too much of a good thing. During the extreme heat of our summers, we don’t want to postpone sunset. Traffic in August is cranky enough already.
Arizona was granted an exception to Daylight Savings Time in the late 1900s due to the extreme heat our state experiences.
