Vienna is 7 hours ahead of Bogotá
Best overlap: 8:00 AM to 11:00 AM in Bogotá is 3:00 PM to 6:00 PM in Vienna.
Keep meetings inside 8:00 AM to 11:00 AM in Bogotá — that maps to 3:00 PM to 6:00 PM in Vienna. Vienna is 7 hours ahead of Bogotá, which gives you a solid 3-hour window. Book earlier in it and neither side is rushing. Finally, Vienna observes daylight saving and Bogotá doesn't, so this window shifts by an hour for part of the year — recheck it each spring and autumn.
