Bucharest is 1 hour ahead of Budapest
Best overlap: 8:00 AM to 5:00 PM in Budapest is 9:00 AM to 6:00 PM in Bucharest.
If you set up a recurring sync, 8:00 AM to 5:00 PM in Budapest (9:00 AM to 6:00 PM in Bucharest) is the natural home for it. Despite the 1-hour difference, a 9-hour overlap keeps things simple and gives both teams breathing room.
