We get an extra hour of sleep when Daylight Saving Time ends, which is when clocks are set back one hour. In 2025, this will occur on Sunday, November 2. At 2 a.m. local time, clocks are turned back to 1 a.m., theoretically granting people an extra hour of sleep that night. However, research indicates that many people do not fully capitalize on this extra hour of sleep because the body's internal clock may disrupt sleep patterns for several days following the change.
