The hour changes for daylight saving time typically at 2:00 AM local time when clocks are either set forward or backward by one hour. In 2025, for regions observing daylight saving time such as most parts of the US and Europe:
- The clocks move forward one hour at 2:00 AM on Sunday, March 9 in the US (spring forward).
- The clocks move back one hour at 2:00 AM local time on Sunday, November 2 in the US (fall back).
For many European countries, including the Netherlands:
- The hour changes at 2:00 AM on the last Sunday in March (Monday 3:00 AM after setting forward) to begin daylight saving time.
- The hour changes again at 3:00 AM on the last Sunday in October (going back to 2:00 AM) to end daylight saving time.
Specifically for 2025 in the Netherlands, the clock will go forward 1 hour at 2:00 AM on Sunday, March 30, and go back 1 hour at 3:00 AM on Sunday, October 26.
