Taipei is 6 hours ahead of Rome
Best overlap: 8:00 AM to 12:00 PM in Rome is 2:00 PM to 6:00 PM in Taipei.
Book within 8:00 AM to 12:00 PM Rome time (2:00 PM to 6:00 PM in Taipei) and both teams will be at work. Taipei is 6 hours ahead of Rome, so the practical overlap is about 4 hours — generous enough for meetings, tight enough to be worth booking ahead. For part of the year the maths changes: Rome observes daylight saving, Taipei does not, shifting the overlap by an hour.
