Hanoi is 12 hours ahead of Chicago

There is no standard 8-to-6 overlap. Someone joins early or late.

Hanoi is 12 hours ahead of Chicago, which is far enough that a normal 9-to-5 in one city never reaches the other's working hours. One practical option: Chicago dials in early while it's still late afternoon or evening in Hanoi. Finally, Chicago observes daylight saving and Hanoi doesn't, so this window shifts by an hour for part of the year — recheck it each spring and autumn.
