Daylight saving time will conclude on Sunday, Nov. 2, 2025, at 2 a.m. Clocks will revert back one hour, allowing people to gain an extra hour of sleep. This change means that when the clock strikes 2 a.m., it will roll back to 1 a.m. However, this shift also means that evenings will become darker earlier, with sunset occurring around 4:30 p.m. in many areas following the change.

Daylight saving time, which began in the U.S. over a century ago, has been a topic of ongoing debate. Some argue for its abolition, citing potential health risks associated with the time change. Dr. Tara Narula, a chief medical correspondent, noted that adjusting to the time shift can take several days. "We know that it takes sometimes seven days to weeks, really, for us to adjust," she said. Many medical organizations advocate for a standard time that aligns better with natural daylight hours.

Historically, daylight saving time was first implemented in the U.S. in 1918 as a measure to conserve energy during World War I. The practice was temporarily abandoned but was reinstated during World War II. The Uniform Time Act of 1966 established a consistent schedule for daylight saving time across the country, which currently runs from the second Sunday in March to the first Sunday in November.

While most states observe daylight saving time, Hawaii and most of Arizona do not participate. Additionally, several U.S. territories, including American Samoa, Guam, Puerto Rico, and the U.S. Virgin Islands, also do not observe the time change.

Efforts to make daylight saving time permanent have gained traction in recent years. In January 2025, the Sunshine Protection Act was reintroduced in Congress, aiming to eliminate the biannual clock changes. However, a recent bipartisan bill that would allow states to opt for permanent daylight saving time was blocked in Congress, leaving the future of the practice uncertain.

Public opinion on daylight saving time has shifted significantly. A recent Gallup poll indicated that 54% of Americans support abolishing the clock changes, a notable decrease from 74% in 1990. As discussions continue, many states are pushing for legislation to establish year-round daylight saving time, but any changes will require federal approval.

As the end of daylight saving time approaches, experts recommend gradually adjusting sleep schedules to ease the transition. Dr. Narula advises shifting bedtimes and wake times by 10 to 15 minutes in the days leading up to the change. This can help mitigate potential disruptions to sleep patterns and overall well-being.

Looking ahead, daylight saving time will resume on Sunday, March 8, 2026, when clocks will spring forward one hour at 2 a.m. Until then, Americans will revert to standard time, with discussions about the future of this practice continuing in legislative chambers across the country.
