Daylight Saving Time Begins Sunday As Clocks Spring Forward

Daylight Saving Time Begins Sunday As Clocks Spring Forward...

Millions of Americans will lose an hour of sleep this weekend as daylight saving time starts at 2 a.m. local time on Sunday, March 13. The annual time change is trending today as people prepare to adjust their clocks and debate the practice's continued relevance.

The shift means later sunsets but darker mornings for most of the country. Only Hawaii and most of Arizona (except the Navajo Nation) remain on standard time year-round. The change comes as Congress continues debating the Sunshine Protection Act, which would make daylight saving time permanent.

Sleep experts warn the time change can disrupt circadian rhythms for days. Studies show increased risks of heart attacks, strokes, and car accidents in the week following the spring transition. Many Americans report grogginess and decreased productivity at work on "Sleepy Monday."

Public opinion appears divided. A 2026 YouGov poll shows 48% of Americans prefer permanent daylight saving time, while 33% favor permanent standard time. The remaining 19% want to keep the current twice-yearly switch. Business groups argue extended daylight hours boost retail sales, while educators cite safety concerns about darker winter mornings.

The time change occurs as many smart devices automatically adjust, but manual clocks in cars, microwaves, and other appliances still require updates. Fire departments traditionally use the event to remind citizens to check smoke detector batteries.

Daylight saving time will end on November 6, 2026, when clocks fall back one hour. Until then, Americans can expect sunsets after 7 p.m. in most locations, with the latest occurring around the summer solstice in June.
