The clocks change for daylight saving time in 2025 as follows:
- In the United States, clocks "spring forward" one hour at 2 a.m. on Sunday, March 9, 2025, starting daylight saving time. They "fall back" one hour at 2 a.m. on Sunday, November 2, 2025, ending daylight saving time.
- In the United Kingdom, the clocks go forward one hour at 1 a.m. on the last Sunday in March (March 30, 2025) to start British Summer Time (BST) and go back one hour at 2 a.m. on the last Sunday in October (October 26, 2025).
- In most of Europe (e.g., Germany, Austria), clocks move forward one hour at 2 a.m. on the last Sunday in March (March 30 to 3 a.m.) and move back one hour at 3 a.m. on the last Sunday in October (October 26 to 2 a.m.).
Summary:
- US: March 9 (2 a.m. forward), November 2 (2 a.m. back)
- UK: March 30 (1 a.m. forward), October 26 (2 a.m. back)
- Europe: March 30 (2 a.m. forward), October 26 (3 a.m. back)
This practice shifts daylight to later in the evening during the summer months. The mnemonic to remember is "spring forward, fall back," meaning clocks go forward in spring and back in fall.
