Adelaide is 13.5 hours ahead of Caracas

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

Adelaide is 13.5 hours ahead of Caracas, which is far enough that a normal 9-to-5 in one city never reaches the other's working hours. One practical option: Caracas dials in early while it's still late afternoon or evening in Adelaide. Keep an eye on the calendar — Adelaide observes daylight saving and Caracas doesn't, which nudges this window by an hour twice a year.
