Does the gap change during the year?

Yes, because of daylight saving. Until 1 Nov 2026: MST is 14 h behind AWST. From 1 Nov 2026 to 14 Mar 2027: MST is 15 h behind AWST. From 14 Mar 2027 to 7 Nov 2027: MST is 14 h behind AWST.

AWST 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).
