Understanding the -1h Gap: Berlin vs London
Berlin runs on Central European Summer Time (CEST) at UTC+02:00, currently observing daylight saving time. London runs on British Summer Time (BST) at UTC+01:00, also currently on daylight saving time. That puts Berlin 1 hour behind London — a difference of -1h at the current offsets.
In practice, when it is 9:00 AM in Berlin it is 8:00 AM in London. Midnight in Berlin is 11:00 PM in London. Because both zones shift for daylight saving, the gap between them only changes during the few weeks each year when their transition dates differ.

Why people convert Berlin to London time
- Scheduling a call from Berlin to London: a 10:00 AM start in Berlin lands at 9:00 AM in London, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Berlin and London are inside the 9-to-5 working day between 10:00 AM and 5:00 PM CEST time (9:00 AM–4:00 PM BST). That is roughly 7 hours of usable overlap.
- Coordinating a Berlin-based team with London contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM CEST" is unambiguous; "3 PM" across a -1h gap is not.
- Block 10:00 AM–5:00 PM CEST as the recurring meeting window if you work primarily from Berlin and need London colleagues present.
- Berlin: Clocks fall back on Sun, Oct 25, 2026. Re-check this page after that date because the offset changes and so does the -1h gap.
- London: Clocks fall back on Sun, Oct 25, 2026. Any meeting series spanning that date will shift by an hour in local time.
About CET (Central European Time)
Central European Time (CET) is the standard time zone for most of Europe, covering over 30 countries from Spain to Poland, and from Norway to Italy.

GMT is often used interchangeably with UTC (Coordinated Universal Time), although technically they are different – UTC is based on atomic clocks while GMT is based on Earth's rotation.
