London–Sydney time difference
London uses GMT (UTC+0) and BST (UTC+1); Sydney uses AEST (UTC+10) and AEDT (UTC+11). Under the current rules, the UK changes on the last Sundays in March and October, while New South Wales changes on the first Sundays in October and April. Sydney is 11 hours ahead when London is on GMT and Sydney is on AEDT, 9 hours ahead when London is on BST and Sydney is on AEST, and 10 hours ahead while both observe daylight time in the transition gaps. Thus 13:00 in London is 00:00 the next day, 22:00 the same day, or 23:00 respectively in Sydney. Verify the live local hour and date because time-zone rules can change.
