One zone, no daylight saving

India keeps a single clock at UTC+05:30 for the whole country and does not observe daylight saving. That makes IST itself simple and everything else slightly awkward: the half-hour offset means gaps to other zones are rarely whole hours, and those gaps move whenever the other country shifts. Our guides cover the history, the conversions and the practical scheduling.
