Daylight saving
Pacific Time changes its clocks twice a year; India Standard Time does not.
The same conversion works for every city on these clocks, such as India to California, India to Los Angeles and Delhi to California.

About the two zones
India Standard Time (IST)
India Standard Time is UTC+5:30 all year. The whole country keeps a single clock, and India has not observed daylight saving time since the 1940s, so IST never changes.
IST can also stand for Irish Standard Time or Israel Standard Time. On this site IST always means India Standard Time (Asia/Kolkata).
Pacific Time (PST / PDT)
Pacific Time follows the clock in Los Angeles: Pacific Standard Time (PST, UTC−8) in winter and Pacific Daylight Time (PDT, UTC−7) during US daylight saving time.
IANA zone
America/Los_Angeles
Offset
UTC−8 standard, UTC−7 daylight saving
Used in
the US West Coast and British Columbia
Major cities
Los Angeles, San Francisco, Seattle, Vancouver, Las Vegas, Portland
PST is often used loosely for Pacific Time all year. In summer the correct abbreviation is PDT; the converter uses whichever applies on your date.
