Does the gap change during the year?
Yes, because of daylight saving. Until 1 Nov 2026: HST is 7 h behind AST. From 1 Nov 2026 to 14 Mar 2027: HST is 6 h behind AST. From 14 Mar 2027 to 7 Nov 2027: HST is 7 h behind 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). HST does not change its clocks.
