Quick answers

Does the gap change during the year?

Yes, because of daylight saving. Until 1 Nov 2026: IST is 10 h 30 min ahead of CST. From 1 Nov 2026 to 14 Mar 2027: IST is 11 h 30 min ahead of CST. From 14 Mar 2027 to 7 Nov 2027: IST is 10 h 30 min ahead of CST.

CST next changes its clocks on 1 Nov 2026 (back 1 h, to UTC−6), then on 14 Mar 2027 (forward 1 h, to UTC−5). IST does not change its clocks.
