If you are scheduling a call between Karachi and Lisbon, the overlap window is limited to typical business hours. When it is 1 pm in Karachi it is 9 am in Lisbon — a workable window for scheduling. The latest reasonable overlap is around 5 pm in Karachi (1 pm in Lisbon). Outside this window there is effectively no good overlap for regular office hours.
Karachi and Lisbon have a comfortable window for a family call — no awkward alarms required. Karachi is 4 hours ahead of Lisbon, which gives you 4 hours of genuine overlap when both sides are free. Aim for between 6 pm and 10 pm in Karachi — that lands at 2 pm to 6 pm in Lisbon, 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.
