Sydney to London: the time difference

On 2026-10-05 at 9:00 AM in Sydney, it is 11:00 PM in London (Sunday, October 4, 2026). London is 10 hours behind of Sydney.

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. London is often described as being on GMT, but it uses British Summer Time during part of the year. Choosing Europe/London keeps both seasons attached to the same calendar event.
