Does the gap change during the year?

Yes, because of daylight saving. Until 1 Nov 2026: KST is 11 h 30 min ahead of NST. From 1 Nov 2026 to 14 Mar 2027: KST is 12 h 30 min ahead of NST. From 14 Mar 2027 to 7 Nov 2027: KST is 11 h 30 min ahead of NST.

NST next changes its clocks on 1 Nov 2026 (back 1 h, to UTC−3:30), then on 14 Mar 2027 (forward 1 h, to UTC−2:30). KST does not change its clocks.
