Why Choose Our IST to PST Converter

Align IST–PST Meetings Instantly

With 13 hours and 30 minutes between IST and PST, business-hours overlap is limited. This tool instantly shows which hours work on both sides, so you can lock in a meeting without a chain of "does 3 PM work for you?" emails.

Spot Date-Line Shifts at a Glance

A IST evening at 9 PM is already the previous afternoon in PST. This converter flags date changes beside the result — critical when booking flights, hitting deadlines, or scheduling across the India–United States corridor.

Handles DST Transitions Automatically

The half-hour offset between IST (UTC +5:30) and PST (UTC -8) already makes mental math tricky — add Daylight Saving Time and the gap can shift further. This converter uses live UTC offsets, so you're always accurate.

Never Miss a IST-Timed Event

Product launches, sports matches, and webinars are often announced in IST. Convert the event time to PST so you know exactly when to tune in — with a 13 hours and 30 minutes difference, a morning event in India hits the evening in United States.

IST to PST Time Difference, Business Hours, and DST

IST to PST is one of the more useful timezone conversions for calls, deadlines, and travel planning. The current gap is 13 hours and 30 minutes, which means 9:00 AM IST becomes 7:30 PM (previous day) PST and 2:00 PM IST becomes 12:30 AM PST.

This matters when teams in Mumbai and Los Angeles need to align business hours, webinars, or customer-support coverage. Use the chart on this page when you want the exact conversion for today instead of relying on manual offset math.

Daylight saving changes can also shift the gap during the year, so a converter is safer than memorizing a fixed difference. That is especially important for recurring meetings and date-sensitive handoffs.

IST to PST FAQ

Quick answers about daylight saving time, date changes, business-hour overlap, and the most common scheduling questions between India Standard Time and Pacific Standard Time.

What is the time difference between IST and PST?

PST is 13 hours 30 minutes behind IST. IST is UTC +5:30 and PST is UTC −8:00 relative to UTC. PST observes daylight saving but IST does not, so the gap shifts by an hour twice a year. In PST winter the difference is 13 hours 30 minutes; in summer it changes by one hour.

When can IST and PST have business-hour overlap?

There is no clean business-hour overlap between IST and PST — the 13 hours 30 minutes gap pushes at least one side outside 9-to-5. Schedule calls at the very start or end of one party's day.

Does IST or PST observe daylight saving time?

PST observes daylight saving but IST does not, so the gap shifts by an hour twice a year. In PST winter the difference is 13 hours 30 minutes; in summer it changes by one hour.

How do I quickly convert IST to PST?

To convert IST to PST, add 13 hours 30 minutes subtract from the IST time. Example: if it's 10:00 AM IST, it's 21:00 PST that day. The live converter at the top of this page handles DST automatically.

Why is PST↔IST a heavy-traffic conversion?

US West Coast tech (Silicon Valley, Seattle) has the largest single concentration of Indian engineering offshore. The 12.5-13.5 hour gap makes overlap painful — most teams default to one side working odd hours.

When can US West Coast and India both be at work?

There is no clean window. PST 7:00-9:00 AM = IST 8:30-10:30 PM. Either US starts early or India stays late. Most offshore teams split the difference asynchronously and meet only once a week.

What's the gap difference between PST and PDT vs IST?

PST→IST is +13.5 hours (winter). PDT→IST is +12.5 hours (summer). India never changes clocks, so the gap shifts by exactly one hour in March and November when the US switches.
