Taipei is 6 hours ahead of Oslo
Best overlap: 8:00 AM to 12:00 PM in Oslo is 2:00 PM to 6:00 PM in Taipei.
Aim for 8:00 AM to 12:00 PM Oslo time — that's 2:00 PM to 6:00 PM over in Taipei. Around 4 hours of overlap is enough to work comfortably, as long as meetings don't drift to the end of one team's day. Finally, Oslo observes daylight saving and Taipei doesn't, so this window shifts by an hour for part of the year — recheck it each spring and autumn.
