The same conversion works for every city on these clocks, such as India to California, India to Los Angeles and Delhi to California.
Shaded areas follow the official zone boundaries, so a country split across zones is split here too. Hover or tap a region for its local time.
Every hour of Tuesday, October 27, 2026, side by side. Days with a clock change show 23 or 25 rows.
Shaded rows fall inside working hours in both places.

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 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.
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.
PDT is 12 hours 30 minutes behind IST for most of the year (238 days in 2026). The gap is 13 hours 30 minutes for about 18 weeks in 2026.
California uses Pacific Time. PDT is 12 hours 30 minutes behind IST for most of the year (238 days in 2026). The gap is 13 hours 30 minutes for about 18 weeks in 2026. Type any IST time into the IST to PST converter to see the California time for any date.
9:00 AM IST is 8:30 PM (previous day) PDT for most of the year (238 days in 2026). 9:00 AM IST is 7:30 PM (previous day) PST for about 18 weeks in 2026.
12:00 PM IST is 11:30 PM (previous day) PDT for most of the year (238 days in 2026). 12:00 PM IST is 10:30 PM (previous day) PST for about 18 weeks in 2026.
10:00 AM IST is 9:30 PM (previous day) PDT for most of the year (238 days in 2026). 10:00 AM IST is 8:30 PM (previous day) PST for about 18 weeks in 2026.
5:00 PM IST is 4:30 AM PDT for most of the year (238 days in 2026). 5:00 PM IST is 3:30 AM PST for about 18 weeks in 2026.
No, PST is behind IST. PDT is 12 hours 30 minutes behind IST for most of the year (238 days in 2026). The gap is 13 hours 30 minutes for about 18 weeks in 2026.
Working days of 9 AM to 5 PM do not overlap. The least disruptive slot is around 6:00 AM IST, which is 5:30 PM (previous day) PDT while IST and PDT apply.
Pacific Time changes its clocks twice a year; India Standard Time does not. The next change is on Sunday, November 1, 2026 in Pacific Time.
IST can also stand for Irish Standard Time or Israel Standard Time. On this site IST always means India Standard Time (Asia/Kolkata).
