This PST to IST converter turns any time in Pacific Standard Time (PST) into India Standard Time (IST), using your device clock so daylight saving is applied automatically. IST is 13 hours 30 minutes ahead of PST when both zones are on standard time, and 12 hours 30 minutes ahead during the summer months when clocks have shifted. PST is UTC−8 (PDT: UTC−7); IST is UTC+5:30.
PST covers Los Angeles, San Francisco, Seattle; IST covers Mumbai, Delhi, Bengaluru. Because only PST observes daylight saving time, the difference is not constant through the year. The tables below show both cases, and the converter at the top always uses the rule in force on the date you pick.

Frequently asked questions
What is the time difference between PST and IST?
IST is 13 hours 30 minutes ahead of PST on standard time. During daylight saving the gap changes to 12 hours 30 minutes. That comes from the UTC offsets: PST is UTC−8 and IST is UTC+5:30. For example, 9 am PST = 10:30 pm IST, and in summer 9 am PST = 9:30 pm IST.
Is IST ahead of or behind PST?
IST is 13 hours 30 minutes ahead of PST, so when it is noon in PST it is 1:30 am in IST the next day. Ahead means the clock there already shows a later time; a call at 5 pm PST lands at 6:30 am IST.
Does PST or IST observe daylight saving time in 2026?
PST switches to PDT (UTC−7) on March 8 and back on November 1 in 2026. IST keeps UTC+5:30 all year. Between those dates the difference in the table above shifts by an hour, which is the usual cause of missed calls in spring and autumn.
What is the best time for a meeting between PST and IST?
Office hours (9 am to 5 pm) do not overlap at all with a 13 hours 30 minutes difference. The least painful options are early morning in PST or early evening in IST; for example 8 am PST = 9:30 pm IST and 6 pm PST = 7:30 am IST the next day. Rotate the inconvenient slot between the two sides for recurring calls.
Which cities use PST and IST?
PST (Pacific Standard Time) is used in Los Angeles, San Francisco, Seattle, Vancouver. IST (India Standard Time) is used in Mumbai, Delhi, Bengaluru, Kolkata. Some cities inside a zone skip daylight saving, noted in parentheses, so their offset matches only part of the year.
