Clocks in most of the United States jump forward an hour on Sunday, March 8, 2026, at 2:00 a.m. — that's the moment Daylight Saving Time begins, and you lose an hour of sleep to gain an hour of evening daylight. * Clocks fall back on Sunday, November 1, 2026, at 2:00 a.m., when Daylight Saving Time ends and the country returns to Standard Time — the "extra hour" everyone looks forward to in the fall. * Both of these are the earliest possible dates the changes can occur under current U.S. law. Daylight Saving Time always starts on the second Sunday in March and ends on the first Sunday in November, and in 2026 the calendar lines up so both fall on the earliest Sunday that rule allows. * Not every state changes its clocks. Arizona (outside the Navajo Nation) and Hawaii stay on Standard Time year-round, so residents there can ignore both dates entirely. Most U.S. territories — Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Northern Mariana Islands — also skip the switch. * Practical tip: most smartphones, computers, and connected devices update automatically at 2 a.m. local time. Anything that doesn't — an oven clock, a car dashboard, a wall clock — you'll need to change by hand.
