IST to PST for every hour
Each PST column holds for part of the year (dates in the header for 2027). The first uses the fixed offsets (IST UTC+5:30, PST UTC−8); the others give local clock time when daylight saving time changes the gap. Until 1:30 PM IST, PST is still on the previous calendar day.

Does the difference change during the year?
As written, no: IST is always UTC+5:30 and PST is always UTC−8, so the gap is 13 hours 30 minutes on every date. But Los Angeles uses PST only in winter, and people often keep writing “PST” when they mean the local time. Between the local clocks of India and Los Angeles, the gap is 13 hours 30 minutes or 12 hours 30 minutes:
| From | What changes | India | Los Angeles | PST vs IST |
|---|---|---|---|---|
| January 1 | Start of the year | IST (UTC+5:30) | PST (UTC−8) | −13 h 30 min |
| March 8 | Los Angeles moves to PDT (UTC−7) | IST (UTC+5:30) | PDT (UTC−7) | −12 h 30 min |
| November 1 | Los Angeles moves to PST (UTC−8) | IST (UTC+5:30) | PST (UTC−8) | −13 h 30 min |

Converting IST to PST by hand
With the fixed offsets, take away 13 hours 30 minutes: 3:30 PM IST is 2:00 AM PST. In your head it is easier to swap AM and PM, then take away 1 hour 30 minutes: 3:30 PM, 3:30 AM, 2:00 AM.
With the −12 h 30 min gap (Mar 14 – Nov 7), take away 12 hours 30 minutes: 3:30 PM IST is 3:00 AM PST. In your head it is easier to swap AM and PM, then take away 30 minutes: 3:30 PM, 3:30 AM, 3:00 AM.
Going back from PST to IST, do the opposite: the PST to IST page has its own table.
Where the IST and PST working days overlap
IST to PST (−13 h 30 min): Two 9:00–17:00 days do not overlap at all. To meet between 7:00 AM and 9:00 PM on both sides, start at 7:00 AM to 10:00 AM IST (5:30 PM to 8:30 PM PST), or 9:00 PM IST (7:30 AM PST).
−12 h 30 min (between Mar 14 and Nov 7, 2027): Two 9:00–17:00 days do not overlap at all. To meet between 7:00 AM and 9:00 PM on both sides, start at 7:00 AM to 9:00 AM IST (6:30 PM to 8:30 PM PST), or 8:00 PM to 9:00 PM IST (7:30 AM to 8:30 AM PST).
A meeting fixed in one city’s calendar moves by an hour for the other when the gap changes. Calendar apps handle this when the event is saved in a named zone (for example Asia/Kolkata) rather than as a fixed offset.
What IST and PST mean
India Standard Time
IST here is India Standard Time, UTC+5:30, used in all of India all year: no daylight saving time and a single zone for the whole country.
IST can also mean Israel Standard Time (UTC+2, Israel) or Irish Standard Time (UTC+1, Ireland, in summer). This page uses India Standard Time, the meaning people searching for this conversion have in mind. For another one, type the city into the time zone converter.

PST can also mean Philippine Standard Time (UTC+8, the Philippines). This page uses Pacific Standard Time, the meaning people searching for this conversion have in mind. For another one, type the city into the time zone converter.
