Why Arizona and Hawaii Don’t Follow Daylight Saving Time—And the Unique Reasons Behind It

Every year, millions of Americans adjust their clocks to accommodate Daylight Saving Time (DST). However, two states—Arizona and Hawaii—stand apart by refusing to participate in this time-changing tradition.
But why? What makes these two states so different that they have opted out of something the rest of the country follows? Let’s explore the surprising reasons behind their decision and how daylight saving time affects daily life across the nation.
The Purpose of Daylight Saving Time
A Time-Saving Idea That Dates Back Over a Century
The concept of daylight saving time originated in 1895 when New Zealand scientist George Hudson proposed the idea of adjusting the clocks to make better use of daylight hours. The goal was simple: shift one hour of daylight from the morning to the evening, reducing energy consumption by minimizing the use of artificial lighting.
Although the idea was initially met with skepticism, it gained momentum during World War I when nations sought ways to conserve energy. The United States officially adopted daylight saving time in 1918, with President Woodrow Wilson signing the Standard Time Act into law. This move was intended to cut electricity costs by maximizing natural light in the afternoons.
Since then, most U.S. states have followed the tradition of adjusting their clocks twice a year—springing forward in March and falling back in November.
However, not everyone agrees with this system. Some states and territories believe DST disrupts their daily lives rather than benefiting them.
How Daylight Saving Time Works in the U.S.
Every year, daylight saving time begins on the second Sunday of March when clocks are moved forward one hour at 2:00 a.m. This shift transitions the country from standard time to daylight saving time, giving people an extra hour of daylight in the evening.
Then, on the first Sunday in November, the clocks are set back an hour, returning to standard time for the fall and winter months.
States That Follow Daylight Saving Time
Currently, 48 U.S. states abide by this practice, adjusting their clocks in accordance with daylight saving rules. The only two states that don’t? Arizona and Hawaii.

Why Arizona and Hawaii Are Exempt from Daylight Saving Time
While most of the U.S. follows daylight saving time, Arizona and Hawaii have chosen to opt out. But why do these two states refuse to follow the tradition? The reasons lie in geography, climate, and lifestyle preferences.
Hawaii: Close to the Equator, No Need for Time Changes
Hawaii, known for its tropical beaches and year-round warm temperatures, sits close to the equator. This location means that sunrise and sunset times remain relatively constant throughout the year.
- Unlike northern states, which experience drastic differences in daylight hours between summer and winter, Hawaii’s daylight schedule doesn’t fluctuate much.
- Because of this consistency, changing the clocks would offer little benefit to residents.
- Instead, adjusting the time would only create unnecessary disruptions to daily life.

Arizona: Avoiding the Heat of Extended Daylight Hours
Arizona’s decision to reject daylight saving time is tied to its desert climate. Unlike many other states that welcome longer daylight hours in summer, Arizona’s residents see things differently.
The state experiences scorching hot summers, with temperatures often exceeding 100°F (37°C). Extending daylight hours in the summer would mean longer, hotter afternoons—something most people would rather avoid.
Businesses, workers, and families preferred to keep the current time schedule rather than adjust their clocks twice a year.
Arizona officials decided that switching to daylight saving time would make already unbearable summer temperatures even worse.
Instead of benefiting from extra evening sunlight, residents would face longer, hotter afternoons, making outdoor activities uncomfortable.
Exception: The Navajo Nation
Interestingly, not all of Arizona follows standard time year-round. The Navajo Nation, which extends across Arizona, Utah, and New Mexico, does observe daylight saving time.
This means that within Arizona itself, there are areas that do change their clocks, while the rest of the state remains on standard time.
Other U.S. Territories That Do Not Follow DST
In addition to Arizona and Hawaii, five U.S. territories also refuse to observe daylight saving time. These territories include:

Like Hawaii, these territories are located in tropical regions, where daylight hours remain relatively stable throughout the year. The lack of seasonal variations makes daylight saving time unnecessary.
The Debate Over Daylight Saving Time: Should It Be Abolished?
The debate surrounding daylight saving time has intensified in recent years. Many Americans question whether the twice-yearly clock change is still relevant in today’s world.
Arguments Against DST
- Disrupts Sleep Patterns – Studies suggest that the time shift negatively affects people’s health, causing sleep disturbances, fatigue, and increased risks of heart attacks in the days following the time change.
- Limited Energy Savings – The original reason for DST was to reduce electricity usage, but modern lighting and energy-efficient appliances have minimized the impact of shifting the clocks.
- Economic Costs – Businesses and airlines often face scheduling challenges due to the inconsistency of time zones between states that do and don’t observe DST.
Arguments in Favor of DST
Reduces Crime Rates – With more daylight in the evening, crime rates—especially those involving theft and burglary—have been reported to decrease in areas that observe DST.
More Evening Daylight – Advocates argue that longer daylight hours encourage outdoor activities, boost mental health, and increase economic activity.
Traffic Safety – Some studies indicate that DST may reduce car accidents by improving visibility during peak commuting hours.
Final Thoughts
Daylight saving time remains a hotly debated topic across the U.S., with some states pushing for permanent DST, while others advocate for eliminating it altogether.
Arizona and Hawaii have proven that not every place benefits from daylight saving time. With Hawaii’s steady daylight hours and Arizona’s extreme heat, these states had compelling reasons to opt out.
As discussions continue, one question remains: Should the entire country follow their lead?
