Does the gap change during the year?

Yes, because of daylight saving. Until 31 Oct 2026: MST is 4 h ahead of HST. From 31 Oct 2026 to 13 Mar 2027: MST is 3 h ahead of HST. From 13 Mar 2027 to 6 Nov 2027: MST is 4 h ahead of HST.

HST does not change its clocks. MST next changes its clocks on 1 Nov 2026 (back 1 h, to UTC−7), then on 14 Mar 2027 (forward 1 h, to UTC−6).
