A Wyoming lawmaker is leading the charge to end Daylight Saving Time (DST) in the state. Representative Dan Zwonitzer, a Republican from Cheyenne, has introduced a bill that would end the tradition of turning clocks forward in the spring and back in the fall, a change that many people have found increasingly unnecessary and disruptive.
If passed, the bill would keep Wyoming on standard time year-round, meaning the state would no longer shift between Mountain Standard Time (MST) and Mountain Daylight Time (MDT). This change would align with efforts in several other states and countries to reconsider or end Daylight Saving Time.
What is Daylight Saving Time and Why Do We Have It?
Daylight Saving Time was first introduced during World War I as a way to save energy by making better use of natural daylight in the evening hours. The idea was to shift an hour of daylight from the morning, when people were still asleep, to the evening, when they could use it more effectively.
In the United States, DST is observed from the second Sunday in March to the first Sunday in November, though some states have opted out or chosen to experiment with different schedules. Over the years, however, there has been growing criticism of DST. Critics argue that the energy savings are minimal at best and that the time changes disrupt sleep patterns, leading to health issues and decreased productivity.
Why Wyoming Wants to End DST
Rep. Zwonitzer’s proposal comes as part of a broader effort to reevaluate the need for Daylight Saving Time. According to him, the time changes have negative effects on people’s lives and are no longer necessary in a modern society. “It’s time to end the practice that disrupts our routines and makes it harder to adjust to the changing seasons,” he said.
Zwonitzer believes that staying on standard time year-round would provide a more stable and predictable schedule for Wyoming residents. This stability, he argues, would be better for mental health, productivity, and overall well-being, particularly as the state moves into the winter months when the days are shorter.
Many people in Wyoming, like those in other states, have long expressed frustration with the twice-yearly time changes. From missed appointments to disrupted sleep, the effects of DST have been a source of annoyance for many. In fact, studies show that the transition into and out of DST is often associated with an increase in accidents, heart attacks, and even strokes. By eliminating the practice, Zwonitzer hopes to reduce these risks and improve public health.
Other States Are Considering the Change
Wyoming is not alone in its efforts to end Daylight Saving Time. Several other states have made moves to either abolish or alter their observance of DST. Hawaii and most of Arizona already remain on standard time year-round, and in recent years, states like California and Florida have considered or passed legislation to make DST permanent.

At the federal level, there have been discussions about making DST permanent across the country. A bill introduced in the U.S. Senate last year, known as the Sunshine Protection Act, would make DST permanent nationwide. However, the bill has yet to be passed into law, and some states, like Wyoming, prefer to maintain control over their time-keeping decisions.
Potential Benefits of Ending Daylight Saving Time
Advocates for ending Daylight Saving Time argue that it would lead to several benefits. Here are some reasons why many believe it’s time to get rid of the time change:
- Improved Health: The disruption caused by shifting the clocks forward and back can have serious health consequences. It can cause sleep deprivation, which in turn affects mood, cognitive function, and overall health. By keeping the clocks the same throughout the year, people would likely experience better sleep and improved well-being.
- Reduced Stress: The time change can add extra stress to people’s lives, especially in the days following the transition. For many, adjusting to the new time means losing an hour of sleep, which can be particularly difficult for children, elderly individuals, and people with certain health conditions. Keeping a consistent time year-round could help reduce this stress.
- Increased Productivity: With no need to adjust to different time schedules, people may find that they are more productive and have a better work-life balance. Consistent sleep patterns and fewer disruptions can improve overall energy levels and focus.
- Less Risk of Accidents: Studies have shown that the transition into DST often leads to an increase in accidents and injuries. The disruption to sleep patterns can make people less alert and more prone to accidents. Eliminating DST could reduce these risks.
- More Time for Outdoor Activities: Without the need to adjust to a different time twice a year, families and individuals could enjoy more consistent daylight hours in the evening, allowing for more outdoor activities, whether it’s hiking, biking, or spending time with loved ones.
Challenges to Ending DST
While there are clear benefits to ending Daylight Saving Time, the proposal is not without its challenges. For one, some people enjoy the extended daylight hours in the summer that DST provides. Businesses, especially those in retail and tourism, also argue that the extra hour of daylight helps drive consumer activity and boosts the economy. Additionally, there are concerns about how ending DST might affect industries that rely on precise timekeeping, such as aviation and broadcasting.
In addition, not all states may be ready to make the change. Some lawmakers argue that the issue of timekeeping should be handled at the federal level, ensuring consistency across the country. They worry that a patchwork of states with different time rules could create confusion and complications.
The Future of Daylight Saving Time in Wyoming
As Rep. Zwonitzer’s bill moves through the Wyoming legislature, it remains to be seen whether the state will follow in the footsteps of other regions that have made changes to DST. If the bill passes, Wyoming would be one of the few states to permanently stay on standard time, and it could set a precedent for other states to follow.
In the meantime, residents of Wyoming will have to continue adjusting their clocks twice a year as the debate over Daylight Saving Time continues across the country.
