Best time for work calls
If you are scheduling a call between Chennai and London, the overlap window is limited to typical business hours. When it is 1 pm in Chennai it is 9 am in London β a workable window for scheduling. The latest reasonable overlap is around 5 pm in Chennai (12 pm in London). Outside this window there is effectively no good overlap for regular office hours.
Best time for family calls
Chennai and London have a comfortable window for a family call β no awkward alarms required. Chennai is 4.5 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 Chennai β that lands at 1:30 pm to 5:30 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.
