Does the gap change during the year?

Yes, because of daylight saving. Until 1 Nov 2026: AST is 11 h behind SGT. From 1 Nov 2026 to 14 Mar 2027: AST is 12 h behind SGT. From 14 Mar 2027 to 7 Nov 2027: AST is 11 h behind SGT.

SGT does not change its clocks. 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).
