Best Hours to Schedule London–Paris Calls
With 9-to-5 days on both sides, the shared window is 9:00 AM to 4:00 PM in London, which is 10:00 AM to 5:00 PM in Paris. That's 7 hours. Paris's 5 PM close is what ends it, so London still has an hour of its day left. A call that starts at 9:00 AM in London is already one hour into the Paris day.

"Inside 9 AM–5 PM" is a planning assumption for a standard office day on each side, not a claim about any company's hours.
About London (GMT/BST)
London is on GMT (UTC+0) in winter and BST (UTC+1) in summer. The offset to Paris doesn't depend on which one applies, because both cities switch on the same weekend. The only conversion step is adding one hour: 2:00 PM in London is 3:00 PM in Paris, in January and in July.
About Paris (CET/CEST)
Paris uses Central European Time (CET, UTC+1) in winter and Central European Summer Time (CEST, UTC+2) from the last Sunday in March to the last Sunday in October. Going the other way, take an hour off a Paris time: 9:00 AM in Paris is 8:00 AM in London.
How to Avoid London–Paris Conversion Mistakes
From 11:00 PM GMT/BST onward, Paris is already on the next calendar day. For example, 11:00 PM GMT/BST is 12:00 AM in Paris on the next day (GMT/BST → CET/CEST).
The usual error is the one-hour step in the wrong direction. Paris is ahead, so a Paris time is always later on the clock than the London time. If you read 3:00 PM in Paris as 4:00 PM in London, you're an hour out; it's 2:00 PM. Calendar apps handle this correctly when both attendees' cities are set, so check the city on the invite before you check the hour.
Worked Example: Booking Back-to-Back Calls Across Both Cities
Say you have a 9:00 AM call in London and want a Paris call right after. The London call ends at 10:00 AM, which is 11:00 AM in Paris. A Paris call booked for 10:30 AM Paris time is 9:30 AM in London, so it would overlap your London call by half an hour. The earliest clean start is 11:00 AM Paris time.
Keep in mind that a Paris-hosted invite stored in Paris time and a London-hosted invite stored in London time both stay correct through the spring and autumn clock changes, since both cities move on the same dates.
