Bucharest is 3 hours behind Karachi
Best overlap: 11:00 AM to 6:00 PM in Karachi is 8:00 AM to 3:00 PM in Bucharest.
Both offices are open during 11:00 AM to 6:00 PM Karachi time, which is 8:00 AM to 3:00 PM in Bucharest. Scheduling is forgiving here: with 7 hours of overlap, a missed slot just means picking another one the same day. Because only Bucharest changes its clocks, the overlap above isn't fixed; expect a one-hour shift when Bucharest enters or leaves daylight saving.
