The Very Simple Reason Why Nevada Doesn’t Do Daylight Saving Time (Along with THIS State)

Nevada, like Arizona, does not observe Daylight Saving Time (DST), and the reason is quite simple: the state is in a region where the long summer days can make the shift unnecessary, and the benefits of saving daylight don’t The “very simple reason” is that Nevada, along with Arizona, doesn’t observe Daylight Saving Time primarily because it’s a hot desert state.

The argument is that having an extra hour of daylight in the evening during the summer would be a disadvantage, not a benefit. Here’s a breakdown:

• Arizona: The state officially opted out of the Uniform Time Act of 1966, which standardized Daylight Saving Time for the rest of the country. Their main reasoning was to avoid the extreme heat. With summer temperatures regularly soaring above 100°F, having an extra hour of evening sun would mean people would run their air conditioners and other cooling systems for a longer period of time, leading to higher energy consumption. By staying on Standard Time year-round, the sun sets an hour earlier, allowing for more outdoor activity during the cooler parts of the evening. The exception is the Navajo Nation, which observes DST to align with tribal lands in Utah and New Mexico.
  
• Nevada: While Nevada currently observes Daylight Saving Time, there have been recent and ongoing legislative efforts to join Arizona and Hawaii in permanently opting out. The motivation is similar to Arizona’s—the intense heat and a desire to avoid the clock changes. Lawmakers and citizens have expressed support for ending the practice, citing health benefits from maintaining a consistent circadian rhythm and the desire to avoid the late summer sunsets that make it difficult for people to go about their evening routines. As of mid-2025, a bill to end DST in Nevada has passed the Assembly and is headed to the Senate.

The other U.S. state that does not observe Daylight Saving Time is Hawaii. Its location near the equator means that the sunrise and sunset times do not vary enough throughout the year to justify the practice. The amount of daylight is relatively consistent, making the time change unnecessary.
