Hong Kong is 12 hours ahead of Washington, D.C.
There is no standard 8-to-6 overlap. Someone joins early or late.
Don't expect an easy slot here: Washington, D.C. and Hong Kong are 12 hours apart, with no overlap across conventional business hours. A shared overlap of zero doesn't mean zero collaboration; it just means leaning harder on documentation and clear ownership. One seasonal catch: Washington, D.C. springs forward and falls back, but Hong Kong doesn't, so the gap changes by an hour for several months of the year.
