London to Sydney: the time difference

On 2026-10-05 at 9:00 AM in London, it is 7:00 PM in Sydney (Monday, October 5, 2026). Sydney is 10 hours ahead of London.

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. 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.
