Best time to meet between Washington, D.C. and Perth

The 12-hour offset between Washington, D.C. and Perth means there's no point hunting for a 9-to-5 overlap — there isn't one. Expect compromise: someone in Washington, D.C. or Perth will need to take the call outside the usual 9-to-5, so share that load. Finally, Washington, D.C. observes daylight saving and Perth doesn't, so this window shifts by an hour for part of the year — recheck it each spring and autumn.
