Miami is 12 hours behind Taipei
There is no standard 8-to-6 overlap. Someone joins early or late.
Taipei and Miami live on different parts of the day. With 12 hours between them, standard working hours simply don't meet. Make the most of handoffs — end-of-day in one city becomes start-of-day in the other, so pass work along rather than meeting live. Seasonal note: Miami uses daylight saving and Taipei doesn't, so double-check the times in your own months — they can move by an hour.
