Best time for work calls
If you are scheduling a call between Tehran and London, the overlap window is limited to typical business hours. When it is 11 am in Tehran it is 9 am in London β a workable window for scheduling. The latest reasonable overlap is around 5 pm in Tehran (2 pm in London). Outside this window there is effectively no good overlap for regular office hours.
Best time for family calls
Tehran and London have a comfortable window for a family call β no awkward alarms required. Tehran is 2.5 hours ahead of London, which gives you 4 hours of genuine overlap when both sides are free. Aim for between 6 pm and 10 pm in Tehran β that lands at 3:30 pm to 7:30 pm in London, 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.
