Does the gap change during the year?
Yes, because of daylight saving. Until 1 Nov 2026: BST is 3 h ahead of AST. From 1 Nov 2026 to 14 Mar 2027: BST is 4 h ahead of AST. From 14 Mar 2027 to 27 Mar 2027: BST is 3 h ahead of AST. From 27 Mar 2027 to 30 Oct 2027: BST is 4 h ahead of AST. From 30 Oct 2027 to 7 Nov 2027: BST is 3 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). BST next changes its clocks on 28 Mar 2027 (forward 1 h, to UTC+1), then on 31 Oct 2027 (back 1 h, to UTC+0).
