Dhaka is 4 hours ahead of Warsaw
Best overlap: 8:00 AM to 2:00 PM in Warsaw is 12:00 PM to 6:00 PM in Dhaka.
Both offices are open during 8:00 AM to 2:00 PM Warsaw time, which is 12:00 PM to 6:00 PM in Dhaka. With 6 hours in common, treat scheduling almost as if the two cities were in the same region. The window above shifts seasonally: Warsaw keeps daylight saving while Dhaka ignores it.
