New York to Sydney: The 14–16 Hour Pacific Gap
New York and Sydney are about as far apart as two major business cities get: the gap is 14 to 16 hours, and because the seasons are flipped, their daylight-saving periods barely overlap. That makes scheduling a puzzle — but a solvable one.
Time Zone Overview
New York (EST/EDT)
New York is on Eastern Time: EST (UTC-5) in winter, EDT (UTC-4) during US DST (second Sunday March to first Sunday November).
Sydney (AEST/AEDT)
Sydney is AEST (UTC+10) in winter and AEDT (UTC+11) during Australian DST (first Sunday October to first Sunday April).
Time Difference
Australian summer / US winter: Sydney is 16 hours ahead of New York.
Australian winter / US summer: Sydney is 14 hours ahead of New York.
Overlap weeks: During the brief windows when only one side has switched, the gap is 15 hours.
Conversion Formula
Sydney time = New York time + 16h (US winter) or + 14h (US summer)

Best overlap for a call?
