Good to know
India keeps a single time zone, UTC+5:30, with no daylight saving — CSIR-NPL maintains Indian Standard Time as UTC(NPLI) plus 5:30 hours — so only the US clock change moves the gap: 10½ hours in winter, 9½ in summer.

When the difference changes
IST is 9½ or 10½ hours ahead of EST — in 2026:
- Until 8 March: 10½ hours ahead
- From 8 March to 1 November: 9½ hours ahead
- From 1 November: 10½ hours ahead
The gap moves because the two places change their clocks on different dates, or only one of them changes at all.
