How Time Zone Conversion Works
Time zone conversion works by comparing the UTC offset of one location to another. Every city or region is measured relative to Coordinated Universal Time (UTC), which acts as the global reference point for civil time.
IST is 15 hours 30 minutes ahead of HST (standard time).
Daylight Saving Time: Neither HST nor IST observes Daylight Saving Time. The 15h 30m offset is constant year-round with no seasonal variation.

HST · Hawaii Time
Standard offset −10:00

IST · India Time
Standard offset +05:30
India Time remains on a constant standard offset for the year.
India does not observe daylight saving time. The IST offset of UTC+5:30 is constant year-round. Note: 'IST' is sometimes ambiguous — it can also refer to Irish Standard Time (Ireland's summer time). On TimeAtlas, IST refers exclusively to India Standard Time.
