Time Difference: London and Berlin
Berlin is 1 hour ahead of London, all year. When it's 9:00 AM in London, it's 10:00 AM in Berlin.
Daylight saving note: The UK and Germany change their clocks on the same weekends, the last Sunday in March and the last Sunday in October, so Berlin is always 1 hour ahead.
Berlin Is One Hour Ahead, Whatever the Season
Germany uses Central European Time (CET) in winter and Central European Summer Time (CEST) in summer. London uses GMT and BST. Both pairs switch on the same weekends, so Berlin stays exactly one hour ahead of London.
That makes conversions a plain +1 or -1. 4:45 PM in London is 5:45 PM in Berlin, and a 9:00 AM start in Berlin is 8:00 AM in London. There's no seasonal column to check.
The one place a mistake can appear is the end of the day. 11:00 PM in London is 12:00 AM the next day in Berlin, so the Berlin calendar is already on the next date for anything after 11:00 PM London time.

Best Meeting Time for London and Berlin
The overlap covers most of the day. If both sides work 9 AM to 5 PM, the window is 9:00 AM to 4:00 PM in London, which is 10:00 AM to 5:00 PM in Berlin. Berlin is the side that runs out first, so a decision that needs a live answer from Germany is best booked before 4:00 PM London time.
Avoiding London-Berlin Time Mistakes
Berlin is ahead, so a late evening in London is already the next calendar day in Berlin. With a 1 hour gap, that starts at 11:00 PM in London: 11:30 PM there is 12:30 AM the next day in Berlin.
If you're sending a deadline for "end of day", say which city's day. Midnight in London is 1:00 AM in Berlin, so a cut-off that's still today in London has already passed in Germany. Include both times in the message.
A Worked Example: Booking Back-to-Back Calls With Berlin
Say you have a London call at 10:00 AM and want a Berlin call straight after. The London call ends at 11:00 AM, which is 12:00 PM in Berlin. A Berlin colleague who proposes 11:00 AM their time is asking for 10:00 AM in London, so the two calls would start at the same moment.
The simplest approach is to set up the Berlin call for 12:00 PM Berlin time (11:00 AM in London). That starts the moment your London call ends, with no gap to travel or switch tools.
For an afternoon slot, count backwards from Berlin's close. 5:00 PM in Berlin is 4:00 PM in London, so a London team that wants Berlin on the line should book before 4:00 PM their time. The shared window from 9:00 AM to 4:00 PM in London is 10:00 AM to 5:00 PM in Berlin.
A good invite title names both cities: "Call, 2:00 PM London / 3:00 PM Berlin". Because both clocks move on the same weekends, you never need to rewrite the title when the clocks change. That makes this pair a good candidate for a recurring series with a fixed one-line format.
If a Berlin colleague forwards a time without a city, convert it before replying. 3:00 PM in Berlin is 2:00 PM in London, and 4:00 PM is 3:00 PM. A reply of "fine, see you then" to the wrong city's time is how an hour slips through.
