How to use it

  1. Enter time in pst and day in pst (optional).
  2. The result appears straight away and updates as you edit.
  3. Copy the result, or copy a link that keeps the same values to share it.

How it is calculated

IST time = PST time + 13.5 hours, because IST is UTC+5:30 and PST is UTC-8. If the result reaches 24:00 or more, subtract 24 hours and move to the next day; if it drops below 00:00, add 24 hours and move to the previous day.

Example

Inputs: Time in PST = 22:00, Day in PST (optional) = Thursday. Result: Time in IST: 11:30; Day change: Next day (+1); Offset difference (IST minus PST): 13.5 hours.

Limits and caveats

  • Fixed offsets are used: PST = UTC-8 and IST = UTC+5:30, whatever the date.
  • Los Angeles switches to PDT (UTC-7) from the second Sunday of March to the first Sunday of November; the tool does not apply that change.
  • IST here is India Standard Time (UTC+5:30), not Irish or Israel time.
