Daylight saving time 2026 start date and key details

Daylight saving time begins on March 8, 2026, at 2 a.m. local time, when clocks will spring forward one hour, resulting in a loss of sleep for many Americans. This annual practice, which shifts an hour of daylight from morning to evening, has been observed on the second Sunday of March since 2007. While daylight saving time was initially introduced during World War I to conserve energy, its actual impact on energy savings has been minimal, and only Hawaii and Arizona do not participate.
