Germany uses Central European Time (CET, UTC+1) in winter and Central European Summer Time (CEST, UTC+2) in summer. The entire country observes a single timezone — there are no regional differences.
DST in 2025: clocks spring forward one hour at 2:00 AM on Sunday 30 March, and fall back at 3:00 AM on Sunday 26 October. This schedule is synchronized across the European Union. Germany has observed CET since standardization in 1893, making it one of Europe's longest-established timezone conventions.
During CET (October–March), Germany is 1 hour ahead of the UK, 6 hours ahead of New York (EST), and 7 hours behind Tokyo. During CEST (March–October), Germany aligns with Greece, Romania, Turkey (which no longer observes DST and stays on UTC+3 year-round), Israel, and South Africa.
Berlin, Munich, Hamburg, Frankfurt, Cologne, and all other German cities operate on the same clock. Germany is the largest economy in the EU and a key scheduling anchor for European business hours, with core office hours running 9 AM–6 PM CET/CEST.
