Islamabad is 4 hours ahead of Rome
Best overlap: 8:00 AM to 2:00 PM in Rome is 12:00 PM to 6:00 PM in Islamabad.
If you set up a recurring sync, 8:00 AM to 2:00 PM in Rome (12:00 PM to 6:00 PM in Islamabad) is the natural home for it. Because you share 6 hours of the workday, there's no need to compromise; book the time that suits the meeting, not the map. Because Rome and Islamabad don't both observe daylight saving, plan to re-check the overlap around March and November.
