New York to Sydney Time Converter

Sydney is 16 hours ahead of New York in the northern winter and 14 hours ahead from April to October. 9:00 AM in New York is 1:00 AM the next day in Sydney in January and 11:00 PM in July.

A Monday Evening in New York Is Tuesday in Sydney

Sydney is 14 to 16 hours ahead of New York, so from 8:00 or 10:00 AM in New York (depending on the season) it is already tomorrow in Sydney. 7:00 PM on Monday in New York is 11:00 AM the next day in Sydney in January and 9:00 AM the next day in July. Going the other way, Sydney's 9:00 AM start is 5:00 PM the previous day in New York in January and 7:00 PM the previous day in July.

Because of that, a 9-to-5 day in Sydney runs from 5:00 PM the previous day to 1:00 AM in New York in January, and a 9-to-5 day in New York is 1:00 AM to 9:00 AM the next day in Sydney. There is no hour that is inside both.

Three Gaps and When Each One Applies

Both countries change their clocks, in opposite halves of the year, so the gap moves four times a year:

Queensland, Western Australia and the Northern Territory do not change their clocks, so for Brisbane or Perth the gap moves only when New York does.

A New York Evening for a Sydney Morning

The workable slots are a New York evening, which is the Sydney morning of the next day, and a New York early morning, which is the Sydney late evening. In January 5:00 to 7:00 PM in New York is 9:00 AM to 11:00 AM the next day in Sydney. In July the same Sydney hours are two hours later in New York, because the gap is 14 hours.

"Inside 9 AM–5 PM" is a planning assumption for a standard office day on each side, not a claim about any company's hours.
