The best time for a call

A 9-to-5 day in New York and one in Sydney don’t overlap at all, so somebody has to stretch. The fairest one-hour slot is usually 5:30 PM in New York, which is 7:30 AM the next day in Sydney. It asks New York to stay about an hour and a half late and Sydney to start about an hour and a half early.

Sydney’s summer is New York’s winter. Both cities change their clocks, but in opposite directions and at different times of year, so the gap drifts between 14 and 16 hours. For most of New York’s working day, Sydney is already on the following date.

The workable slot is late afternoon in New York and early morning in Sydney: about 5 p.m. Eastern in the northern winter, closer to 7 p.m. in the northern summer. Friday afternoon in New York is already Saturday in Sydney.

Why the time difference changes

New York and Sydney sit in different hemispheres, so their summers, and their daylight saving seasons, fall at opposite ends of the calendar. New York: clocks go forward on the second Sunday in March and back on the first Sunday in November. Sydney: clocks go forward on the first Sunday in October and back on the first Sunday in April.

Each of those four changes moves the gap by an hour, which is why it drifts across a two-hour range during the year.
