Quick answer
Add 13 hours 30 minutes to convert PST to IST. 9:00 AM PST is 10:30 PM IST, and 6:00 AM PST is 7:30 PM IST. PST is UTC−8. IST is UTC+5:30.
Pacific daylight time
PDT is UTC−7. Add 12 hours 30 minutes: 9:00 AM PDT is 9:30 PM IST, and 8:00 AM PDT is 8:30 PM IST. When the US West Coast enters or leaves daylight saving time, India does not. A standing call shifts by one hour on the India clock unless you move the Pacific time.
Overlap is narrow
A normal Pacific morning is already evening in India. 9:00 AM Pacific is 10:30 PM IST in standard time and 9:30 PM IST in daylight time. Late Pacific afternoon is after midnight in India. Teams usually meet at the edge of one workday, then rotate who takes the inconvenient hour.
Write the labels carefully
PST is only the standard-time label. If the date might be in summer, write PT or Pacific Time and IST, and include the date. IST on this page is India Standard Time, not Irish Standard Time.
