Osaka is 13 hours ahead of Atlanta

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

Osaka is 13 hours ahead of Atlanta, so their typical working days don't line up at all. Plan on one side joining outside normal hours. A recurring slot that trades off between early mornings and late evenings usually works best. Because only Atlanta changes its clocks, the overlap above isn't fixed; expect a one-hour shift when Atlanta enters or leaves daylight saving.
