Does the gap change during the year?

Yes, because of daylight saving. Until 1 Nov 2026: NST is 6 h behind IRST. From 1 Nov 2026 to 14 Mar 2027: NST is 7 h behind IRST. From 14 Mar 2027 to 7 Nov 2027: NST is 6 h behind IRST.

IRST does not change its clocks. 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).
