Sydney time zone
Sydney uses Australian Eastern Standard Time (AEST, UTC+10) in its winter and Australian Eastern Daylight Time (AEDT, UTC+11) in its summer. The IANA zone is Australia/Sydney, which covers New South Wales and Canberra.
Daylight saving in New South Wales starts at 2am on the first Sunday in October and ends at 3am on the first Sunday in April. The next change is on Sunday 4 October 2026, when Sydney moves to AEDT. Because Sydney's summer is the UK's winter, the two places move their clocks in opposite directions, and the gap swings by two hours over the year.

The 10-hour rows are the weeks when both countries are on summer time at once. Sydney changes at 2am or 3am on a Sunday, which is Saturday afternoon in the UK, so the new gap starts on the UK's Saturday.

There is almost no overlap in office hours. In the British summer a UK call at 8am catches the end of the Sydney working day. In the British winter the practical slot is a UK evening, which is the next morning in Sydney.
Converting the time
9am in London is 6pm in Sydney in the British summer and 8pm in the British winter. Sydney is often already on tomorrow's date: from 1pm UK time in winter, or 3pm in summer. That is why the midnight New Year fireworks over Sydney Harbour are shown live in the UK at 1pm on 31 December. For other times, use the time zone converter or the meeting planner.
