A 2h time gap separates Istanbul (UTC+3) and London (UTC+1). When you pick up your morning coffee in London, your counterpart in Istanbul is already a few hours into their day. Getting a meeting right means understanding exactly where those working days intersect.

With 6h of shared business hours, there's enough room for one focused daily meeting. The discipline is keeping it exactly that: focused. 2h gaps don't forgive meeting sprawl — a 30-minute standup that runs to 45 minutes starts eating into someone's actual work time. Book it, timebox it, end it on schedule.

The less obvious scheduling risk is daylight saving time mismatch. Istanbul and London may not shift their clocks on the same date. A meeting booked as "10 AM IST" in January might show up as "11 AM IST" in a colleague's calendar in March if your calendar app doesn't handle DST transitions correctly. Check the DST note on this page before setting up recurring meetings.

Add the rest of your team above and the planner scales to everyone at once. A three-city team spanning Istanbul, London, and a third timezone often has less overlap than any two-city pair in isolation — surfacing that constraint early prevents scheduling that works on paper but burns people out in practice.

Daylight saving time: London observes daylight saving time; Istanbul does not. When London's clocks change (next: March 29), the gap between the two cities shifts by 1 hour.
