Clocks Fall Back Early Sunday In Nevada

Daylight saving time ends before dawn Sunday, Nov. 1, for Clark County residents. Clocks must be set back one hour at 2 a.m., giving people an extra hour of sleep. Mornings will have more light and darkness will arrive earlier in the evening.

Most cellphones adjust on their own. Owners of analog clocks need to turn them back manually.

Daylight saving time was first adopted in the United States through the Standard Time Act of 1918. Congress has considered ending the practice several times since.

A proposal called the Sunshine Protection Act would make daylight saving time permanent. The measure would keep clocks moved forward in March rather than returning to standard time in November, extending evening light during winter months. The bill is unlikely to pass this year. President Trump has supported the change and urged people in Arkansas to contact Sen. Tom Cotton, a Republican who opposes the bill because children would attend school in the dark.

Some sleep scientists and doctors want standard time made permanent instead, saying it supports healthier sleep cycles and lowers health risks. Other research indicates permanent daylight saving time could increase vehicle collisions involving pedestrians during darker morning commutes.

States may opt out of daylight saving time with congressional approval. Hawaii, most of Arizona, and U.S. territories do not change clocks. California voters approved ending daylight saving time in 2018, but legislative efforts to enact the change have since failed. Daylight saving time resumes March 14, 2027.

Nevada observes daylight saving time. Residents should turn analog clocks back one hour at 2 a.m. Nov. 1.
