The clock changes twice a year for Daylight Saving Time (DST). In 2025, the clocks go forward one hour on Sunday, March 30, 2025, at 2:00 a.m. (to 3:00 a.m.) to start summer time, and go back one hour on Sunday, October 26, 2025, at 3:00 a.m. (to 2:00 a.m.) to return to winter time.

Details of Clock Changes in 2025

• Spring Forward (start of summer time or DST): March 30, 2025, at 2:00 a.m. clocks move forward to 3:00 a.m.
• Fall Back (end of DST and return to standard time): October 26, 2025, at 3:00 a.m. clocks move back to 2:00 a.m.

This is the usual schedule for many European countries observing Central European Time (CET) and Central European Summer Time (CEST).

Mnemonics to Remember

• "Spring forward, fall back" — clocks move forward in spring and back in autumn.
• Temperature analogy: clocks go forward when temperatures rise (spring), back when temperatures fall (autumn).

This seasonal clock change is intended to make better use of daylight during the longer days of summer.
