Berlin time explained
Berlin runs on Central European Time, the same as Paris, Madrid, Rome and most of continental western Europe. That single zone stretches from Spain to Poland, which is why sunset in western Spain can be more than an hour and a half later than in eastern Poland on the same evening.
Berlin does observe daylight saving, so its offset from UTC changes twice a year. The time above already accounts for whichever is currently in force.
Reaching Berlin
A Berlin afternoon reaches the New York morning; a Berlin morning still catches most of Asia before their day ends. It is one of the better-placed cities for spanning both directions in a single day.
How this page works
The time above is calculated on your own device from the IANA time zone
database that ships with your browser, using the zone
Europe/Berlin. Nothing is fetched from a server, and the offset
shown is whatever is currently in force rather than a
number typed into the page — so when a country changes its rules, this
page changes with it.
The difference from your own clock is worked out the same way, comparing Berlin's current offset against your device's. If your computer's clock is wrong, so is that comparison.
