Bucharest is 6 hours ahead of Caracas
Best overlap: 8:00 AM to 12:00 PM in Caracas is 2:00 PM to 6:00 PM in Bucharest.
For the smoothest call, aim inside 8:00 AM to 12:00 PM in Caracas, i.e. 2:00 PM to 6:00 PM in Bucharest. Bucharest is 6 hours ahead of Caracas, so the practical overlap is about 4 hours — generous enough for meetings, tight enough to be worth booking ahead. Don't be caught out by clock changes — Bucharest observes daylight saving and Caracas doesn't, so the offset varies by an hour through the year.
