What AWST and BST Actually Are
AWST — Australian Western Standard Time
Perth. Standing at UTC+8:00 as written, and the region does not change its clocks, so that offset holds all year. Western Australia does not observe daylight saving, so Perth stays on UTC+8 all year.
Western Australia has held four referendums on daylight saving and rejected it every time, most recently in 2009.
BST — British Summer Time
London, Manchester, Birmingham, Glasgow, and the rest of the UK from late March to late October. Standing at UTC+1:00 as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, October 25, 2026, to GMT. BST also stands for Bangladesh Standard Time (UTC+6). BDT is the clearer label for that one.
British Summer Time began in 1916 as a wartime fuel-saving measure and has run every year since, making it one of the oldest continuous daylight saving schemes in the world.
What This Means in Practice
This gap is not fixed
BST changes its clocks and AWST does not, so the difference between them moves by an hour twice a year. A recurring meeting set now will drift for one side from Sunday, October 25, 2026 unless someone resets it.
