The clocks will be changed in 2025 as follows:
- In Europe (including Germany and Central European Time), clocks will move forward one hour to start Daylight Saving Time (summer time) on the last Sunday in March, which is March 30, 2025, at 2:00 a.m. The clocks are set forward from 2:00 a.m. to 3:00 a.m., making the night one hour shorter.
- Clocks will move back one hour to end Daylight Saving Time (return to standard/winter time) on the last Sunday in October, which is October 26, 2025, at 3:00 a.m. The clocks are set back from 3:00 a.m. to 2:00 a.m., making the night one hour longer.
- In the United Kingdom, the clocks will also go back by one hour on October 26, 2025, at 2:00 a.m., marking the end of British Summer Time.
- In the United States, Daylight Saving Time in 2025 starts on the second Sunday in March (March 9, 2025) and ends on the first Sunday in November (November 2, 2025) though the user query "20" seems to refer to 2025 but not specific to the US change dates.
So, for Europe, clocks change on March 30 (spring forward) and October 26 (fall back) in 2025. For the US, the change is March 9 and November 2, 2025.
