Most places that observe Daylight Saving Time set clocks forward once a year in early spring, but the exact date depends on where you live.

United States

  • In most of the U.S., clocks go forward on the second Sunday in March at 2:00 a.m. , jumping to 3:00 a.m.
  • For 2026, that date is Sunday, March 8, 2026 , when clocks move from 2:00 a.m. to 3:00 a.m. local time.
  • A few places, like most of Arizona and Hawaii , do not observe Daylight Saving Time at all.

United Kingdom

  • In the UK, the clocks go forward on the last Sunday in March , marking the start of British Summer Time (BST).
  • In 2026, that is Sunday, 29 March 2026 , when clocks move forward one hour at 1:00 a.m. GMT.
  • A common way to remember it is the phrase “spring forward, fall back.”

Europe (general pattern)

  • Most of Europe follows a similar rule to the UK, moving clocks forward by one hour on the last Sunday in March.
  • In 2026, many European countries will also set clocks forward on March 29, 2026 , just like the UK.

Quick way to remember

  • You set clocks forward in spring (losing one hour of sleep but gaining lighter evenings).
  • You set clocks back in autumn/fall , gaining an extra hour of sleep but earlier sunsets.

If you share your country or region, a more precise date and time can be given for your location.
