EST to AEST
From New York, Sydney is a day ahead: add 16 hours in January, 14 hours in July and 15 hours during the weeks in March, April, October and November when only one side has changed its clocks. 6:00 PM Eastern is 10:00 AM the next day in Sydney in winter and 8:00 AM in summer.

The 6 PM Eastern call
There is no overlap between a New York and a Sydney office day, so the usual compromise is an East Coast evening and an Australian morning. 6:00 PM in New York is 10:00 AM the next day in Sydney from November to March, 9:00 AM during the transition weeks and 8:00 AM from April to October. Move the call to 7:00 PM Eastern in the northern summer if Australian colleagues start at 9.
Friday is the trap. 5:00 PM Friday in New York is already 9:00 AM Saturday in Sydney in January, so anything sent at the end of the American week sits until Monday in Australia. Send Australian requests by Thursday evening Eastern, which is Friday morning in Sydney.
Opposite seasons, opposite calendars
Australian summer runs from December to February, and many businesses slow down from Christmas until school returns in late January. Australia's financial year runs from July 1 to June 30, so June is year-end crunch for Sydney finance teams while New York is heading into summer. Plan audits, budgets and contract renewals with that calendar in mind; days between dates helps count the working days across the break.
American sport also lands at odd hours. The Super Bowl kicks off around 6:30 PM Eastern on a Sunday in February, which is about 10:30 AM on Monday in Sydney, so Australian fans watch it on a workday morning.
