Taipei is 14 hours ahead of Calgary
There is no standard 8-to-6 overlap. Someone joins early or late.
Calgary and Taipei are 14 hours apart, and that gap is wide enough that their normal 9-to-5 workdays never quite touch. If you meet regularly, fix one off-hours slot and rotate it between Calgary and Taipei so the burden doesn't fall on one team. Because Calgary and Taipei don't both observe daylight saving, plan to re-check the overlap around March and November.
