London to Sydney Time Converter

The current time in London and Sydney, every hour converted between them, and when your working days overlap.

The gap changes four times a year because the UK and Australia change their clocks in opposite seasons. Sydney is 11 hours ahead of London from late October to late March, 9 hours ahead from early April to early October, and 10 hours ahead in the weeks between, when both are on summer time. In 2026 Sydney goes back to 11 hours ahead on October 25, when the UK returns to GMT.

The working days meet only at their ends. In the London winter 8 a.m. in London is 7 p.m. in Sydney; in July 8 a.m. in London is 5 p.m. in Sydney. Teams that work across the two cities usually meet early in the London morning, at the end of the Sydney day.
