Notes
AEST (Australian Eastern Time, UTC+10:00) is 10h ahead of GMT (Greenwich Mean Time, UTC+00:00) when both are on standard time. Sydney (Australia) observes daylight saving (AEDT, UTC+11:00) from early October to early April (southern-hemisphere summer). London (UK) observes daylight saving (BST, UTC+01:00) from late March to late October. During transition weeks the two regions may switch on different dates — for exact meeting times use the live converter below, which uses the IANA time-zone database.
Their 9:00–18:00 business hours do not overlap at all — one side has to take an early-morning or late-evening slot.
