Dhaka 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 Dhaka.
Rome and Dhaka overlap from 8:00 AM to 2:00 PM (Rome) to the equivalent 12:00 PM to 6:00 PM in Dhaka — that's your meeting window. Plenty of room to work with: 6 hours of daily overlap means you can prioritise people's preferences over the clock. A quick caveat — Rome's clocks move for daylight saving and Dhaka's don't, so the times here are right for only part of the year.
