Best time to call Chicago from Adelaide

Waking hours, 8 am–10 pm on each clock, overlap 8 am–2:30 pm in Adelaide, which is 3:30–10 pm the day before in Chicago.

That’s for a call outside work: catching someone before or after their working day. For a work call, the meeting hours above fit inside both working days.
