Overview
- Germany moved clocks forward Sunday at 2 a.m. to 3 a.m., cutting one hour from the night and starting Central European Summer Time.
- Legal time is set by PTB’s DCF77 long‑wave signal from Braunschweig, and most phones, computers and TVs follow rules from the IANA time zone database run by volunteers led by Paul Eggert and Tim Parenti.
- Heaters with built‑in timers often do not adjust on their own, so experts urge users to check schedules to avoid an hour‑late morning warm‑up and misaligned night setback.
- Researchers link the spring shift to short‑term sleep loss, daytime fatigue and a higher risk of some heart problems, and sleep doctors suggest morning light and a steady routine to help the body adapt.
- EU plans to end the biannual change remain stalled because member states have not agreed on a permanent standard or summer time.
