Doha is 1 hour ahead of Stockholm
Best overlap: 8:00 AM to 5:00 PM in Stockholm is 9:00 AM to 6:00 PM in Doha.
Your shared working hours run 8:00 AM to 5:00 PM in Stockholm (9:00 AM to 6:00 PM in Doha). The 1-hour gap barely gets in the way — you've got 9 hours of overlap, so pick whatever time fits the agenda. Because only Stockholm changes its clocks, the overlap above isn't fixed; expect a one-hour shift when Stockholm enters or leaves daylight saving.
