Adelaide is 14.5 hours ahead of Bogotá
There is no standard 8-to-6 overlap. Someone joins early or late.
When Bogotá starts work, Adelaide is already winding down or offline — the 14.5-hour gap leaves no shared window. Default to async and only schedule live time when it genuinely needs a conversation — then make it count. Daylight saving complicates things slightly: Adelaide observes it, Bogotá doesn't, so the difference flexes by an hour part of the year.
