Health experts warn of short-term risks from the shift, with competing proposals in Congress to end the biannual change.

Overview

  • Most of the United States advances clocks by one hour at 2 a.m. on Sunday, March 8, with the seasonal schedule running until Sunday, Nov. 1, 2026.
  • Hawaii, most of Arizona, and U.S. territories including Puerto Rico, Guam, American Samoa and the U.S. Virgin Islands do not change clocks, though the Navajo Nation observes the switch.
  • Research cited by medical organizations links the spring transition to temporary increases in fatal crashes, heart attacks and strokes, and experts advise morning sunlight exposure and earlier bedtimes to ease adjustment.
  • The Senate-approved Sunshine Protection Act from 2022 remains stalled in the House, and a new February proposal by Rep. Greg Steube would set the nation permanently a half hour ahead and end clock changes, which would require federal action.
  • British Columbia moves clocks forward Sunday and will remain on daylight time year-round, creating a cross-border difference as U.S. law currently allows only permanent standard time without congressional approval.
