Best time for work calls
If you are scheduling a call between London and Istanbul, the overlap window is limited to typical business hours. When it is 9 am in London it is 11 am in Istanbul β a workable window for scheduling. The latest reasonable overlap is around 3 pm in London (5 pm in Istanbul). Outside this window there is effectively no good overlap for regular office hours.
Best time for family calls
London and Istanbul have a comfortable window for a family call β no awkward alarms required. London is 2 hours behind Istanbul, which gives you about an hour of genuine overlap when both sides are free. Aim for between 6 pm and 7 pm in London β that lands at 8 pm to 9 pm in Istanbul, after the school run and before anyone's ready for bed. For a Sunday catch-up or a midweek check-in, this is the sweet spot.
