Overview
- Clocks in Germany advance from 2:00 to 3:00 during the night of March 28–29, cutting one hour from the night.
- Many devices update automatically via the Physikalisch‑Technische Bundesanstalt time signal, but analog clocks, some car systems and household appliances often require manual adjustment.
- North America switches earlier on March 8–9, temporarily narrowing time differences with Europe by one hour and shifting trading and data-release times.
- British Columbia says this weekend’s change will be its last before ending clock switches, and Ukraine already stopped changing in 2025.
- Health researchers, including a Stanford study and sleep specialists, link the semiannual change to higher risks such as fatigue and hospital admissions, and German labor guidance says the hour between 2 and 3 on March 29 generally need not be worked or paid if paid by the hour.
