Anchorage is 17 hours behind Taipei
Best overlap: 8:00 AM to 11:00 AM in Taipei is 3:00 PM to 6:00 PM in Anchorage.
The overlap falls at 8:00 AM to 11:00 AM in Taipei, or 3:00 PM to 6:00 PM if you're in Anchorage. Roughly 3 hours of common time means scheduling is manageable; just avoid the very edges of the window. The overlap spans the date line; in practical terms, Anchorage is on the previous day compared to Taipei. Because only Anchorage changes its clocks, the overlap above isn't fixed; expect a one-hour shift when Anchorage enters or leaves daylight saving.
