The equivalent India Standard Time (UTC +5:30) time appears immediately. Since IST is 13 hours and 30 minutes ahead of PST, conversions often cross midnight — look for the date-change label.

Why Choose Our PST to IST Converter

Align PST–IST Meetings Instantly

With 13 hours and 30 minutes between PST and IST, 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 PST evening at 9 PM is already the next morning in IST. This converter flags date changes beside the result — critical when booking flights, hitting deadlines, or scheduling across the United States–India corridor.

Handles DST Transitions Automatically

The half-hour offset between PST (UTC -8) and IST (UTC +5:30) 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 PST-Timed Event

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

Business-hours overlap

US West to India — SaaS engineering handovers

The bread-and-butter of SF-based SaaS companies with India engineering teams. PST is 13.5 h behind IST (12.5 h behind during PDT). Practical overlap: 8:30-10 AM PT (9-10:30 PM IST) for start-of-US-day standups. Alternative: 10-11:30 PM PT (11:30 AM - 1 PM IST) — the "late-night PM calls with morning India standups" that engineering managers describe. Handover cycles at scale usually just accept 24-h latency and use async written updates.

The two zones in context

PST vs IST — cities and working rhythm

PST — Pacific Standard Time
Primary cities: Los Angeles, San Francisco, Seattle, Vancouver, San Diego

US West Coast — home of Silicon Valley, LA entertainment, and the SaaS / VC ecosystem. Business hours 9 AM – 6 PM PT. Startup / tech culture stretches later than East Coast: it's common for calendar invites from West Coast product teams to run through 8 PM PT.

IST — India Standard Time
Primary cities: Mumbai, Delhi, Bengaluru, Hyderabad, Chennai, Kolkata

Indian business hours run 10 AM – 7 PM IST typically; IT / BPO shifts commonly extend to cover US and UK working hours, so 3:30 PM – 12:30 AM IST (US overlap) and 12:30 PM – 9 PM IST (UK overlap) are the two second shifts you see most often. Weekend is Saturday-Sunday for most private-sector employers.

Time gap: IST is 13.5 hours ahead of PST (standard-time offsets — daylight-saving flips shift this by an hour twice a year in most northern-hemisphere zones).

PST to IST Time Difference, Business Hours, and DST

PST to IST 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 PST becomes 10:30 PM IST and 2:00 PM PST becomes 3:30 AM (next day) IST.

This matters when teams in Los Angeles and Mumbai 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.

PST to IST FAQ

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

What is the time difference between PST and IST?

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

When can PST and IST have business-hour overlap?

There is no clean business-hour overlap between PST and IST — 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 PST or IST observe daylight saving time?

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

How do I quickly convert PST to IST?

To convert PST to IST, add 13 hours 30 minutes to the PST time. Example: if it's 10:00 AM PST, it's 23:00 IST 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.
