We, the undersigned residents of Clark County, Nevada, respectfully request that our county adopt Mountain Standard Time (MST) year-round. This adjustment would eliminate the twice-yearly clock changes associated with Daylight Saving Time (DST) and provide a more consistent schedule that aligns better with health and societal needs.

Why Mountain Standard Time Year-Round?

Currently, Clark County operates on Pacific Time, but switching to MST permanently would mean later sunsets during the winter months. This change could bring significant benefits to our community, including improved public health, enhanced safety, and economic gains.

 
1. Improved Mental Health and Reduced Seasonal Affective Disorder (SAD)

Sunset occurring an hour later in winter would mean more daylight hours in the evening, when most people are active and able to enjoy outdoor activities. Research shows that increased exposure to natural light can:

• Boost mood and reduce symptoms of depression, including SAD.
• Improve sleep quality by supporting healthy circadian rhythms.

2. Enhanced Physical Health

Longer daylight hours encourage outdoor exercise, which is critical for combating obesity, diabetes, and cardiovascular diseases. A later sunset supports:

• Increased opportunities for outdoor activities after work or school.
• Improved vitamin D levels due to increased sun exposure.

3. Increased Traffic Safety

Studies consistently show that later sunsets lead to fewer accidents, as daylight helps drivers see pedestrians and road hazards more clearly. A permanent MST schedule would help:

• Reduce accidents during the evening rush hour in winter.
• Protect schoolchildren during after-school activities.

4. Economic and Lifestyle Benefits

Businesses benefit from extended daylight hours because consumers are more likely to shop, dine out, and engage in leisure activities in the evening. Additionally, workers enjoy:

• Better work-life balance with more time for evening recreation.
• Fewer disruptions caused by biannual clock changes, which impact productivity.

Why Now?

Many states and regions are reconsidering DST, with growing support for permanent standard time. Adopting MST year-round would place Clark County at the forefront of progressive change, setting an example for the rest of Nevada and neighboring states.

This petition is an opportunity to align our county’s policies with the latest research, enhancing quality of life for all residents.
