Converting London time to Sydney time
Set London as the reference city, then enter the local date and time of your event. The second row shows the corresponding time and date in Sydney. Use the reference selector to convert in the other direction.
Why the date matters
London uses Greenwich Mean Time (UTC+0) in winter and British Summer Time (UTC+1) in summer. Select the actual date of your event to account for clock changes, particularly when comparing with North America.
Sydney uses Australian Eastern Standard Time (UTC+10) and Australian Eastern Daylight Time (UTC+11). Its daylight saving season falls in the opposite part of the year to Europe and North America.
Winter and summer comparison
These examples compare the same instant (12:00 UTC) on two dates. They are examples, not a fixed year-round time difference.
