There is no standard 8-to-6 overlap. Someone joins early or late.
Seoul and New York are too far apart in time (13 hours) for their workdays to line up during regular hours.

London to New York is five hours apart, except for the five weeks a year when it isn't. Exact overlap windows for every US zone, the 2026 DST mismatch dates, and where to put the recurring sync. -
Slack converts timestamps automatically and shows everyone's local time, but it can't fix a bare '3 PM' typed into a channel. The settings worth changing and the habits that do the rest. -
