Does the gap change during the year?
Yes, because of daylight saving. Until 1 Nov 2026: AWST is 11 h ahead of AST. From 1 Nov 2026 to 14 Mar 2027: AWST is 12 h ahead of AST. From 14 Mar 2027 to 7 Nov 2027: AWST is 11 h ahead of AST.
AST next changes its clocks on 1 Nov 2026 (back 1 h, to UTC−4), then on 14 Mar 2027 (forward 1 h, to UTC−3). AWST does not change its clocks.
