What is IST in PST?
Pacific Time is 12 hours 30 minutes behind
India Standard Time is on UTC+5:30 and Pacific Time is on UTC−7:00 right now. Pacific Time is on daylight saving, so its clocks read PDT. The gap changes during the year — see below.

When the difference changes
India Standard Time and Pacific Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:
- Now – November 1, 2026Pacific Time is 12 hours 30 minutes behind
- November 1, 2026 – March 14, 2027Pacific Time is 13 hours 30 minutes behind
- March 14, 2027 – onwardsPacific Time is 12 hours 30 minutes behind
Periods shorter than a day are not listed: both zones change at 2am in their own local time, so there are a few hours on each transition date when the gap is briefly something else.
Daylight saving
India Standard Time
India Standard Time stays on IST all year, so its offset from UTC never moves.
Pacific Time
Clocks go back one hour at 2am local time, becoming PST.

Scheduling between the two
There is no overlap between a nine-to-six working day in New Delhi and one in Los Angeles — the gap is too wide. A call has to sit early or late for one side. Early morning in New Delhi is the usual compromise, since that is late afternoon or evening in Los Angeles.
A note on IST: it can also mean Israel Standard Time (UTC+2) and Irish Standard Time (UTC+1). This page means India Standard Time, which is what almost all searches for IST want.
India Standard Time (IST) is used in all of India and Sri Lanka, on a single UTC+5:30 offset with no daylight saving
Pacific Time (PDT) is used in San Francisco, Seattle, Las Vegas and Vancouver
