New York to Sydney: the time difference

On 2026-10-05 at 9:00 AM in New York, it is 12:00 AM in Sydney (Tuesday, October 6, 2026). Sydney is 15 hours ahead of New York.

New York is a useful anchor for US East Coast business hours. Its clock changes do not line up with London’s, so recurring transatlantic calls can shift for a few weeks each year. Sydney’s summer is the northern hemisphere’s winter. Its daylight-saving changes can move in the opposite direction from those in North America, making a single year-round difference unreliable.
