About IST to PST Converter

Convert India Standard Time to US Pacific time (California, Seattle, Silicon Valley) for any date. Pacific time is 13 hours 30 minutes behind India in winter (PST, UTC−8) and 12 hours 30 minutes behind during US daylight saving (PDT, UTC−7), from the second Sunday of March to the first Sunday of November. India does not change its clocks. The tool uses the right offset for the date you choose, marks when California is on the previous day, and has a meeting planner to find the short window when both sides are at work.

How to Use

Set the India time

India is already in From and Los Angeles in To, at the time now in India. Change the Date and Time, or press Now for the current time.

Read the Pacific time

The result shows the time in Los Angeles with PST or PDT and its UTC offset, a −1 day marker when California is still on the previous date, and how far behind India it is.

Look for an overlap

In Meeting planner, set Working hours from 7 am and to 10 pm to see the early-morning and late-evening India hours that fall in California's working day. Add a city to compare a third office.

Swap for PST to IST

The swap button turns it round, so you can type a California time, such as a stand-up or a product launch, and see it in IST.

Rules & Limitations

US daylight saving runs from 2 am on the second Sunday of March to 2 am on the first Sunday of November (in 2027: 14 March to 7 November). India stays at UTC+5:30 all year.
India and California working days barely overlap. With the default hours of 9 am to 6 pm in both places, the planner finds no common hour.
Pacific time covers California, Washington, Oregon and Nevada; Arizona and other US zones have different times, so pick the right city.
The planner counts Monday to Friday in each city as working days, so a Monday morning in India (still Sunday in California) never counts.

IST to PST Converter FAQ

What is the time difference between India and California?

California is 13 hours 30 minutes behind India in winter (PST) and 12 hours 30 minutes behind from mid-March to early November (PDT). The tool works out the right one for any date.

When can India and California teams meet during work hours?

Usually only at the edges of the day: late evening in India (9–10:30 pm IST is 8:30–10 am PDT or 7:30–9 am PST) or early morning in India (7–8:30 am IST is 6:30–8 pm PDT or 5:30–7 pm PST the previous evening).

Is California on PST or PDT now?

California uses PDT (UTC−7) from the second Sunday of March to the first Sunday of November and PST (UTC−8) the rest of the year. The abbreviation beside the result tells you which applies on your date.

Why is the day different in California?

At 12:30 to 13:30 hours behind, California is still on the previous day until India's early afternoon. The −1 day marker beside the result shows this so you book the right date.

Can I add a third office, such as London, to the planner?

Yes. The planner shows up to four places: the From and To cities plus two more chosen with Add a city. Bengaluru and Seattle are already covered by India and Los Angeles, as they share those time zones.
