Best overlap: 4:00 PM to 6:00 PM in Calgary is 8:00 AM to 10:00 AM in Brisbane.
Aim for 4:00 PM to 6:00 PM Calgary time — that's 8:00 AM to 10:00 AM over in Brisbane. There's just 2 hours of overlap here, so don't leave meetings to chance — lock 4:00 PM in Calgary / 8:00 AM in Brisbane into the calendar. Don't get caught out: Brisbane is the next day from Calgary, so "tomorrow" means different things to each team. Keep an eye on the calendar — Calgary observes daylight saving and Brisbane doesn't, which nudges this window by an hour twice a year.
