Daylight Saving Time in Las Vegas 2026: Dates, History, and Impact

Does Las Vegas Observe Daylight Saving Time?

Yes, Las Vegas, like the rest of Nevada, observes daylight saving time (DST). Nevada follows the Uniform Time Act of 1966, which mandates DST across most of the United States. Las Vegas switches between Pacific Standard Time (PST, UTC-8) in winter and Pacific Daylight Time (PDT, UTC-7) in summer. For details on the city's timekeeping, see our page on the Las Vegas Time Zone — PST/PDT (UTC offset, history).

In 2026, daylight saving time begins on Sunday, March 8, and ends on Sunday, November 1. On March 8 at 2:00 AM local time, clocks spring forward to 3:00 AM PDT. On November 1 at 2:00 AM, clocks fall back to 1:00 AM PST. These transitions align with the federal DST schedule observed across the U.S. (except Arizona and Hawaii).

HISTory of DST in the United States and Las Vegas

Daylight saving time has a long history. The U.S. first adopted DST in 1918 during World War I to conserve fuel. After being repealed and reinstated, the Uniform Time Act standardized it nationwide in 1966. Nevada has consistently observed DST since then. For a deeper dive, check the Las Vegas Time Zone page.

While Las Vegas has always followed federal DST rules, there have been proposals to change them. In recent years, the Sunshine Protection Act (which would make DST permanent) passed the U.S. Senate in 2022 but stalled in the House. If enacted, Las Vegas would remain on PDT year-round. This would affect sunrise and sunset times, especially in winter. For example, in December, sunrise would be after 8 AM instead of before 7 AM.

Public Policy Debates Around DST

The debate over DST continues. Supporters argue it saves energy, reduces traffic accidents, and boosts evening recreation — important for a tourism hub like Las Vegas. Opponents cite health risks from disrupted sleep and minimal energy savings. Nevada has considered legislation to exempt itself, but no bill has passed.
