Best time for work calls
If you are scheduling a call between Buenos Aires and Sydney, there is very limited or no overlap in normal business hours. Consider early-morning or late-evening calls for one side, or use async communication.
Best time for family calls
Buenos Aires and Sydney have a comfortable window for a family call — no awkward alarms required. Buenos Aires is 13 hours behind Sydney, which gives you 3 hours of genuine overlap when both sides are free. Aim for between 7 pm and 10 pm in Buenos Aires — that lands at 8 am to 11 am in Sydney, after the school run and before anyone's ready for bed. For a Sunday catch-up or a midweek check-in, this is the sweet spot.
