Understanding the Sydney – New York City Time Difference
Sydney runs on Australia/Sydney, currently AEDT (UTC+11:00). New York City runs on America/New_York, currently EDT (UTC-4:00). The gap of 15 hours is simply the distance between those two offsets.
Both cities observe Daylight Saving Time, but they don't switch on the same date — so for a few weeks each year the gap between them is different again. The next shift is on Sunday, November 1, 2026, when New York City adjusts its clocks and the difference becomes 16 hours. Anything scheduled across that date needs checking again.
