Time difference between New York and Perth
Perth is 12 hours ahead of New York
New York, the United States is UTC−5 · Perth, Australia is UTC+8 — on standard time
The gap is not the same all year
Every converter gives one number for this pair. That number is right for most of the year and wrong for part of it, because New York goes forward on the second Sunday in March and back on the first Sunday in November and Perth does not change its clocks.
| New York / Perth clocks | Difference | How long |
|---|---|---|
| summer / standard | 12 hours ahead | about 34 weeks — most of the year |
| standard / standard | 13 hours ahead | about 18 weeks |
Perth stays put all year while New York moves, so a meeting fixed in Perth's calendar shifts by an hour twice a year at New York's end.
When they can both be at their desks
Nine-to-five in New York and nine-to-five in Perth do not overlap at all. With 12 hours between them, one side is always outside working hours, and the practical question is which side takes the early start or the late finish rather than when to meet.
