Prague is 5 hours behind Dhaka
Best overlap: 1:00 PM to 6:00 PM in Dhaka is 8:00 AM to 1:00 PM in Prague.
For the smoothest call, aim inside 1:00 PM to 6:00 PM in Dhaka, i.e. 8:00 AM to 1:00 PM in Prague. A 5-hour overlap gives you a workable daily window; aim for earlier in it to avoid clipping the end of someone's day. Seasonal note: Prague uses daylight saving and Dhaka doesn't, so double-check the times in your own months — they can move by an hour.
