Athens is 4 hours behind Hanoi

Best overlap: 12:00 PM to 6:00 PM in Hanoi is 8:00 AM to 2:00 PM in Athens.

Hanoi and Athens overlap from 12:00 PM to 6:00 PM (Hanoi) to the equivalent 8:00 AM to 2:00 PM in Athens — 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 — Athens's clocks move for daylight saving and Hanoi's don't, so the times here are right for only part of the year.
