Oslo is 4 hours behind Dhaka
Best overlap: 12:00 PM to 6:00 PM in Dhaka is 8:00 AM to 2:00 PM in Oslo.
The sweet spot is 12:00 PM to 6:00 PM Dhaka time, matching 8:00 AM to 2:00 PM in Oslo. The 4-hour gap barely gets in the way — you've got 6 hours of overlap, so pick whatever time fits the agenda. Because only Oslo changes its clocks, the overlap above isn't fixed; expect a one-hour shift when Oslo enters or leaves daylight saving.
