Convert IST to PT

India Standard Time (IST) to Pacific Time (PT)

Indian engineers, offshore team leads, and project managers in Bangalore, Hyderabad, and Pune convert to Pacific time daily when coordinating with headquarters in San Francisco, Seattle, or Los Angeles. The large gap means most real-time overlap happens at the edges of each team's day.

When it's 12:00 PM in Mumbai, it's 11:30 PM in Los Angeles (previous day)

On Jan 1 – Mar 7, 2026; Nov 1, 2026 – Mar 13, 2027; Nov 7 – Dec 31, 2027: 10:30 PM in Los Angeles (previous day).

Scheduling Tips

For morning standups with the US West Coast, 9:00-10:00 PM IST / 7:30-8:30 AM PST is the most common slot. Keep it brief.
For demos and reviews, 7:00-8:00 AM IST / 5:30-6:30 PM PST (previous day) lets the US team present at the end of their day while India starts fresh.
Document decisions asynchronously in shared channels. With a 13.5-hour gap, waiting for a live meeting to unblock work can cost an entire day.

Frequently Asked Questions

What is the time difference between IST and PST?

IST (India Standard Time, UTC+5:30) is 13 hours and 30 minutes ahead of PST (Pacific Standard Time, UTC-8). When it is 9:00 AM IST, it is 7:30 PM PST the previous day. During PDT (UTC-7), the gap is 12 hours and 30 minutes.

Does the IST-PST offset change?

It changes when the US moves to or from daylight saving time. India does not observe DST, so IST is always UTC+5:30. During PDT (March-November), the gap shrinks to 12:30. During PST (November-March), it widens to 13:30.

What is 9 AM IST in PST?

9:00 AM IST is 7:30 PM PST the previous day. During PDT, 9:00 AM IST is 8:30 PM PDT the previous day. The start of the Indian workday falls in the previous evening on the US West Coast.

What is 6 PM IST in PST?

6:00 PM IST is 4:30 AM PST the same day. During PDT, 6:00 PM IST is 5:30 AM PDT. End-of-day India falls in the very early morning on the West Coast.

What is 10 PM IST in PST?

10:00 PM IST is 8:30 AM PST the same day. During PDT, 10:00 PM IST is 9:30 AM PDT. This late-evening IST slot catches the start of the US West Coast workday.

What is the best time for IST teams to meet with PST?

The most practical windows are 8:30-10:00 PM IST / 7:00-8:30 AM PST (catching the West Coast morning) or 7:00-8:30 AM IST / 5:30-7:00 PM PST the previous day (catching the West Coast evening).

Does India have multiple time zones?

No. India uses a single time zone (IST, UTC+5:30) across the entire country despite spanning roughly 30 degrees of longitude. There is ongoing debate about adopting two time zones, but as of now IST applies everywhere.
