Time in Germany — regions, cities and time zones

Current time in Berlin

Berlin sets the national reading, though only by convention — Munich, Hamburg, Cologne and Dresden are all on precisely the same clock. The capital is simply the name most conversion tools attach to German time.

The zone identifier you will usually see in software is Europe/Berlin, and it covers the whole federal republic. If a system offers you a separate entry for another German city, it is an alias, not a different offset.

Central European Time and its summer twin

Germany's clock has two settings and they are named separately: CET — Central European Time, UTC+01:00, in force during the colder half of the year CEST — Central European Summer Time, UTC+02:00, in force during the warmer half

Germany does not do this alone. The same pair of offsets and the same switching dates apply across a broad band of neighbouring countries, which is exactly why Central European Time is a useful label rather than a national quirk. Crossing into France, Poland, Austria or the Netherlands does not change your watch.

The clock change

Clocks move forward an hour in spring and back an hour in autumn, in step with the rest of the European Union. The change happens in the small hours, deliberately, so that it lands on as few working schedules as possible.

Two consequences are worth planning around: In spring, one hour simply does not exist. A process scheduled inside it either runs early, runs late, or does not run. In autumn, one hour happens twice. Anything that runs "every hour" will run twice within the same wall-clock hour, and log timestamps become ambiguous unless they carry an offset.

Store the time zone, not the offset. An offset is a fact about a moment; a time zone is a fact about a place.

Regions, borders and one national hour

Germany's sixteen federal states differ on school holidays, public holidays and shop opening rules — but not on time. There is no regional exception, no state that opts out of the summer change, and no historical split still in effect.

The east-west spread of the country does mean real solar differences. The sun comes up noticeably later in the far west than in the far east, particularly in winter, which is a familiar complaint in Aachen and a familiar smugness in Görlitz. The clock stays put regardless.
