DST ends November 2, 2025, clocks back

Daylight Saving Time (DST) in the U.S. ends on Sunday, November 2, 2025, at 2:00 AM local time. At this time, clocks will be set back one hour, granting everyone an extra hour of sleep and signaling the return to Standard Time. This yearly adjustment is intended to make better use of daylight during the shorter days of fall and winter.

DST introduced during World War I for energy

Daylight Saving Time was first introduced during World War I as a way to conserve energy. By extending daylight into the evening hours, countries could reduce their reliance on artificial lighting, which at the time was primarily powered by fossil fuels. The idea was that by shifting the clock, people would use less energy, thereby aiding the war effort. While the energy-saving benefits of DST have been debated in recent years, the practice has remained in place in many countries, including the United States.

Time change affects sleep; adjust gradually

The change can affect sleep schedules, making some people feel tired or disoriented for a few days. To mitigate these effects, experts recommend adjusting your sleep schedule gradually in the days leading up to the time change. This can involve going to bed and waking up a little later each day to ease the transition. Maintaining a consistent sleep routine, even on weekends, can also help regulate your body's natural sleep-wake cycle.
