Does the gap change during the year?
Yes, because of daylight saving. Until 1 Nov 2026: KST is 15 h ahead of MST. From 1 Nov 2026 to 14 Mar 2027: KST is 16 h ahead of MST. From 14 Mar 2027 to 7 Nov 2027: KST is 15 h ahead of MST.
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). KST does not change its clocks.
