Does the gap change during the year?

Yes, because of daylight saving. Until 31 Oct 2026: AST is 7 h ahead of HST. From 31 Oct 2026 to 13 Mar 2027: AST is 6 h ahead of HST. From 13 Mar 2027 to 6 Nov 2027: AST is 7 h ahead of HST.

HST 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).

About HST and AST

AST here means Atlantic Time, the clock in Halifax. Right now it is UTC−3. Strictly, AST is the winter name; in summer these places use ADT. This page follows their real clock all year.
