Sydney is 10 hours ahead of London right now.
Does the gap change?
The gap isn't fixed. London and Sydney both use daylight saving time, but they change their clocks on different dates and in opposite seasons, so the difference moves during the year:
- From around October 25, 2026: Sydney ahead by 11 hours
- From around March 28, 2027: Sydney ahead by 10 hours
- From around April 3, 2027: Sydney ahead by 9 hours
- From around October 2, 2027: Sydney ahead by 10 hours
Best time to meet
Normal office hours in Sydney and London don't overlap. The most workable window is 7 AM to 12 PM in London, which is 5 PM to 10 PM in Sydney, with one side starting early or finishing late.
For a recurring meeting, it's fairest to rotate which city takes the inconvenient slot.
