3. Use the hour table to find times inside office hours in both places (green).

## Questions

### What is the time difference between IST and PST?

13 hours 30 minutes while Los Angeles and San Francisco is on standard time (PST (UTC−8)), and 12 hours 30 minutes during daylight time (PDT (UTC−7)). India does not change its clocks, so the difference changes only when Los Angeles and San Francisco does.

### What is 10 a.m. IST in PST?

8:30 p.m. the previous day in winter (PST) or 9:30 p.m. the previous day in summer (PDT).

### When do the clocks change?

Same US dates as Eastern time: 8 March to 1 November 2026, 14 March to 7 November 2027. The converter shows the next change for both places.

### How is daylight saving worked out?

From the time-zone database built into your browser (the IANA tz database), the same data phones and calendars use, so future and past dates are correct too.

### Does it need an account or send anything?

No. It runs in this page with your device's clock. Nothing is stored on a server.
