U.S. springs forward as Daylight Saving Time begins March 8

Daylight Saving Time begins on Sunday, March 8, 2026, and people are urged to set their clocks ahead by one hour at 2 a.m., a reminder posted on Facebook said.

The annual spring shift moves clocks forward to extend evening daylight and is observed in most U.S. states. Arizona and Hawaii do not observe Daylight Saving Time, nor do U.S. territories including Puerto Rico, Guam, the U.S. Virgin Islands, American Samoa and the Northern Mariana Islands.

The time change can affect sleep patterns, travel schedules and workplace operations. Many smartphones, computers and other digital devices update automatically, but experts often advise that people manually adjust wall clocks, watches and appliances and check smoke and carbon monoxide detector batteries while changing clocks.

Debate continues over whether Daylight Saving Time yields significant energy savings or broader benefits, and its health and safety impacts are the subject of ongoing study. We will provide more information as it becomes available.
