More than 300 million Americans will shift clocks on March 8, 2026, when Daylight Saving Time US 2026 begins. At 2:00 a.m. local time, clocks spring forward to 3:00 a.m., starting longer daylight evenings across most U.S. states. The DST schedule runs until November 1, 2026. The change supports evening commerce, travel schedules, and outdoor activity. However, Arizona and Hawaii skip Daylight Saving Time. Several U.S. territories also stay on standard time year-round. Smartphones adjust automatically, but manual clocks need resetting. Debate continues in Washington over ending DST permanently. For now, Americans still spring forward every March.
