Sydney is 11 hours ahead of London in January and 9 hours ahead in July, because the two zones change their clocks in opposite seasons. London is on UK time, GMT at UTC+0 in winter and BST at UTC+1 in summer. Sydney is on Australian Eastern Time, AEST at UTC+10 in winter and AEDT at UTC+11 in summer. Paste a Unix timestamp, an ISO 8601 string or a plain date such as June 1 2026 3:00 pm and the converter shows that moment in both zones, with UTC and Unix time alongside.
