HST to IST: convert Hawaii Standard Time to India Standard Time

IST is 15:30 hours ahead of HST all year.

Neither clock changes for daylight saving, so the gap never moves.

IST also abbreviates Israel Standard Time (UTC+2) and Irish Standard Time (UTC+1). These pages use the Indian meaning.

Both lanes show the same instant. Local dates, daylight, and offsets come from each IANA zone on the selected date, so daylight saving changes are included.

Scheduling a call between HST and IST

Standard business hours (9:00 AM to 5:00 PM) do not overlap: daytime in Hawaii Standard Time falls outside the working day in India Standard Time, so one side needs an early morning or late evening.
