Best time to schedule a meeting
There is no overlap between a 09:00–18:00 working day in London and one in Sydney — the two are close to opposite sides of the clock. A call has to sit in someone's early morning or evening; the timeline makes it easy to see whose.
Frequently asked questions
How many hours ahead is London of Sydney?
It depends on the season. Around July London is 9 hours behind Sydney; around January it is 11 hours behind Sydney. The switch happens when one of the two moves to or from daylight saving time.
What time is 12:00 noon GMT in AEST?
12:00 noon GMT is 21:00 AEST.
Does GMT or AEST use daylight saving time?
Both GMT and AEST observe daylight saving, but they usually switch on different dates — so for a couple of weeks each spring and autumn the difference is an hour off its usual value.
