Hong Kong is 14 hours ahead of Calgary

There is no standard 8-to-6 overlap. Someone joins early or late.

When Calgary starts work, Hong Kong is already winding down or offline — the 14-hour gap leaves no shared window. Default to async and only schedule live time when it genuinely needs a conversation — then make it count. Note that Calgary follows daylight saving while Hong Kong stays put, so the times above drift by an hour seasonally.
