Overview

• Australia advances clocks by one hour at 2 a.m. on Sunday, Oct. 5 in NSW, Victoria, South Australia, Tasmania and the ACT, while Queensland, Western Australia and the Northern Territory do not observe daylight saving.
• The UK ends British Summer Time at 2 a.m. on Sunday, Oct. 26, returning to GMT as internet-connected devices update automatically and analog clocks require manual changes.
• The United States returns to standard time at 2 a.m. on Sunday, Nov. 2, with exceptions including Hawaii, most of Arizona and several U.S. territories that do not observe daylight saving time.
• Public guidance stresses practical prep such as manually resetting non-connected clocks, replacing smoke and carbon monoxide detector batteries, and easing into new sleep schedules to reduce disruption.
• In the U.S., bills to make daylight saving time permanent remain in congressional committees, and NIST notes the fall transition shifts an hour of daylight back to the morning.
