Daylight Savings Time Starts US
Date: March 8, 2026
Start of Daylight Savings Time U.S.
Most of the United States observes daylight saving time (DST), the practice of setting the clock forward by one hour when there is longer daylight during the day, so that evenings have more daylight and mornings have less.
Exceptions include Arizona (except for the Navajo Nation, which observes daylight saving time), Hawaii, and the territories of American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the United States Virgin Islands.
