Daylight saving time in Sydney and London

Sydney turns the clocks forward from AEST to AEDT at 2:00 AM on the first Sunday in October and back at 3:00 AM on the first Sunday in April, the dates New South Wales, Victoria, South Australia, Tasmania and the ACT share, while Queensland, Western Australia and the Northern Territory do not change their clocks. In 2026 the changes fall on April 5 and October 4, in 2027 on April 4 and October 3.

London turns the clocks forward from GMT to BST at 1:00 AM on the last Sunday in March and back at 2:00 AM on the last Sunday in October, the dates the UK government publishes. In 2026 the changes fall on March 29 and October 25, in 2027 on March 28 and October 31.

The gap takes 3 values across 2026 and 2027: 11 hours, 10 hours, 9 hours. 9 hours holds on most days; the highlighted rows are the 366 days with another gap, because one side has changed its clocks and the other has not:
