Best overlap: 8:00 AM to 12:00 PM in Copenhagen is 2:00 PM to 6:00 PM in Perth.
Plan around 8:00 AM to 12:00 PM in Copenhagen, which is 2:00 PM to 6:00 PM in Perth, to catch everyone during office hours. With 4 hours to play with, a mid-window meeting keeps things balanced for Copenhagen and Perth alike. Don't be caught out by clock changes — Copenhagen observes daylight saving and Perth doesn't, so the offset varies by an hour through the year.
