Seattle is 12.5 hours behind Mumbai

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

When Mumbai starts work, Seattle is already winding down or offline — the 12.5-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 Seattle follows daylight saving while Mumbai stays put, so the times above drift by an hour seasonally.
