Time Difference Between Berlin and San Francisco
San Francisco is 9h behind Berlin when both cities are on standard time and when both are on daylight saving time. San Francisco is 8h behind Berlin during the weeks when one city has changed its clocks and the other has not.
Berlin clocks move forward on the last Sunday of March and back on the last Sunday of October. San Francisco clocks move forward on the second Sunday of March and back on the first Sunday of November. The figures above cover each part of the year. They do not come from the offset on the day the site was built. The live clocks use the current time.
Working Hours Overlap
For each hour of Berlin's working day (9:00-18:00), here is the corresponding local time in San Francisco. Rows highlighted green fall within standard working hours (9:00-18:00) in both cities. Each block is one part of the year, so the table does not change with the day this page was built.

Best Time to Meet
9h behind (standard time and daylight saving time)
Berlin and San Francisco don't share a 9 AM-6 PM working-hours window during standard time and daylight saving time. The least disruptive compromise is around 3 PM in Berlin, which falls at 6 AM in San Francisco. Expect one side to take an early or late call.
8h behind (daylight saving time in San Francisco, while Berlin is on standard time)
- 5 PM-6 PM in Berlin (9 AM-10 AM in San Francisco) works for both sides. It falls within 9 AM-6 PM in both time zones.
How the Difference Changes
The two cities do not change their clocks on the same dates, so the gap is not one number. The rules are above. The dates for the year you are reading this page load below.

Working Across Berlin and San Francisco
Do not put Berlin and San Francisco on a weekly live cadence and then act surprised when it rots. Nine hours apart means 8 AM in San Francisco is 5 PM in Berlin, and 9 AM is 6 PM. That is one hour, sitting on the moment Berlin is trying to leave. The San Francisco afternoon does not exist for Berlin at all. Teams that keep this corridor healthy stop meeting most days. Berlin writes a handoff at the end of its day. San Francisco reads it at the start of theirs, which is the same hour, and replies before Berlin sits down again.
Both cities change clocks, on different dates, and the only comfortable stretch is the mismatch. The gap is nine hours for the long middle of the year. It drops to eight between the second Sunday of March and the last Sunday of March, and again between the last Sunday of October and the first Sunday of November. At eight hours, 8 AM in San Francisco is 4 PM in Berlin and 10 AM is 6 PM, which is a real window instead of a courtesy. It lasts a few weeks in spring and about a week in autumn. Enjoy it, and do not redesign the whole quarter around it. When the nine-hour setting returns, go back to the written handoff.
There is usually no nonstop. A one-stop trip takes most of a day, commonly via London, Frankfurt, or a US hub, and nine hours of clock change sits on top of the cabin. Eastbound asks you to fall asleep in what your body still calls the afternoon. For a trip shorter than a week, a lot of people stay on San Francisco hours and accept odd mealtimes rather than pretending they will adjust. If the trip is the meeting, give yourself a clear day before it.
