Overview
- Most of the United States moves clocks forward one hour at 2 a.m. local time on Sunday, March 8, though Hawaii and most of Arizona do not observe the change.
- The United Kingdom shifts from GMT to BST on Sunday, March 29, and clocks will revert to GMT on October 25.
- Timeanddate.com estimates locations gain just under four minutes of daylight per day throughout March.
- In London, daylight lasts about 11 hours 18 minutes on March 7, 12 hours 41 minutes on March 28, and 12 hours 53 minutes on March 31 after the clock change.
- The Royal Observatory Greenwich says the forward shift means losing an hour’s sleep and offers the reminder to ‘spring forward’ in spring and ‘fall back’ in autumn.
