Technical Time Format Reference
IANA Identifiers: America/Los_Angeles (PST/PDT), Asia/Kolkata (IST)
ISO 8601: 2024-03-15T20:00:00-08:00 (PST) = 2024-03-16T08:30:00+05:30 (IST)
JavaScript: new Date().toLocaleString("en-US", {timeZone: "America/Los_Angeles"})
Python: from zoneinfo import ZoneInfo then datetime.now(ZoneInfo("America/Los_Angeles"))
UTC Offsets: PST = UTC-8, PDT = UTC-7, IST = UTC+5:30
What is Pacific Standard Time / Pacific Daylight Time (PST)?
Pacific Standard Time (PST, UTC-8) is used on the US West Coast during winter months from November to mid-March. During Daylight Saving Time (mid-March to November), the region switches to Pacific Daylight Time (PDT, UTC-7), moving clocks forward one hour. This affects major tech hubs like San Francisco, Seattle, and Los Angeles. The time zone serves over 50 million people across California, Washington, Oregon, and Nevada, making it critical for business coordination with India's tech industry in Bangalore and Hyderabad.
What is Indian Standard Time (IST)?
Indian Standard Time (IST, UTC+5:30) is the single time zone for all of India, maintained year-round without Daylight Saving Time changes. The half-hour offset is unique and based on 82.5E longitude passing through Mirzapur. IST serves over 1.4 billion people across India, from Mumbai's financial district to Bangalore's tech campuses. The consistent UTC+5:30 offset simplifies scheduling for international business, though the lack of DST means the time difference with PST/PDT zones shifts by one hour twice yearly during US DST transitions.
PST to IST Time Difference Explained
Winter (PST to IST): IST is 12.5 hours ahead - when it's 20:00 PST Wednesday, it's 08:30 IST Thursday
Summer (PDT to IST): IST is 13.5 hours ahead - when it's 20:00 PDT Wednesday, it's 09:30 IST Thursday
Transition Complexity: The difference shifts during US DST changes (second Sunday March, first Sunday November)
India Consistency: IST never changes, making it reliable for scheduling
Practical Impact: Most US Pacific evening hours convert to next-day India morning, ideal for early meetings before India's 9 AM work start
Travel Planning: US West Coast to India
Flight Duration: SFO/LAX to BLR/DEL direct = 15-17 hours, typical routes via Middle East hubs
Jet Lag Strategy: India is 12.5 hours ahead - adjust sleep 2-3 hours daily for 4-5 days before departure
Best Departure: Evening US Pacific flights arrive India late evening next day, allowing immediate night rest
Business Travel: Schedule important meetings 2-3 days after arrival to allow acclimatization
Return Adjustment: Westbound travel generally easier - India evening departure reaches US same evening

PST to IST Conversion - Frequently Asked Questions
What is the time difference between PST and IST?
IST (India Standard Time) is 13.5 hours ahead of PST during winter, and 12.5 hours ahead during PDT (summer).
Key conversion examples:
- 00:00 PST = 13:30 IST
- 09:00 PST = 22:30 IST
- 18:00 PST = 07:30 IST (+1 day)
- 22:00 PST = 11:30 IST (+1 day)
India maintains UTC+5:30 year-round (no DST), while US Pacific switches between PST (UTC-8, November-March) and PDT (UTC-7, March-November).
How do I convert PST to IST?
To convert PST to IST:
- Winter (PST): Add 13.5 hours to PST (November-March)
- Summer (PDT): Add 12.5 hours to PST (March-November)
Example conversions:
- 09:00 PST = 22:30 IST (same day)
- 18:00 PST = 07:30 IST (next day)
- 22:00 PST = 11:30 IST (next day)
Use our converter above for automatic DST adjustments and accurate conversions. The tool automatically detects whether PST or PDT is in effect.
What is the best time for meetings between PST and IST zones?
Optimal meeting window: 18:00-22:00 PST = 07:30-11:30 IST (next day) or 06:30-10:30 IST during PDT
This window works best because:
- For US Pacific: Late afternoon/evening hours (end of workday flexibility)
- For India: Early morning business hours (fresh start of day)
- Example: 19:00 PST = 08:30 IST works perfectly for San Francisco-Mumbai teams
Note: The time difference crosses the date line, so late PST evening becomes early IST morning the next day.
Does US West Coast observe Daylight Saving Time?
Yes, US West Coast observes Daylight Saving Time (DST). Pacific Time switches between PST and PDT:
- PST (Winter): UTC-8 (early November to mid-March)
- PDT (Summer): UTC-7 (mid-March to early November)
India does not observe DST, so IST remains constant at UTC+5:30. This means the time difference changes: 13.5 hours during PST season, 12.5 hours during PDT season. Our converter automatically handles these transitions.
What cities are in the PST timezone?
Major cities in PST/PDT (UTC-8/-7):
- Los Angeles, CA - 3.9 million (Entertainment capital)
- San Francisco, CA - 815K (Tech hub)
- San Diego, CA - 1.4 million (Biotech center)
- Seattle, WA - 749K (Tech & aerospace)
- Portland, OR - 653K (Manufacturing)
- Las Vegas, NV - 656K (Entertainment)
- Vancouver, Canada - 675K (International gateway)
These cities switch between PST (winter, UTC-8, November-March) and PDT (summer, UTC-7, March-November). Always verify current DST status when scheduling.
What cities are in the IST timezone?
Major cities in IST (UTC+5:30):
- Mumbai - 20.7 million (Financial capital)
- Delhi - 32.9 million (National capital)
- Bangalore - 12.3 million (Tech hub)
- Kolkata - 14.9 million (Cultural capital)
- Chennai - 10.9 million (Industrial center)
- Hyderabad - 10.0 million (IT services)
- Pune - 6.6 million (Manufacturing & education)
All of India uses a single time zone (IST) and does not observe Daylight Saving Time, making it one of the few large countries with uniform time across all regions.
How do I schedule calls between US West Coast and India?
Best practices for US West Coast-India scheduling:
- Optimal window: 18:00-22:00 PST (07:30-11:30 IST next day or 06:30-10:30 IST during PDT)
- Always specify both local times in meeting invites (e.g., "19:00 PST / 08:30 IST")
- Account for DST transitions: US changes in March/November, India never changes
- Use correct abbreviations: 'PST' for November-March, 'PDT' for March-November
- Consider date change: Late PST evening crosses into next day IST morning
Popular meeting times: 19:00 PST = 08:30 IST (team standups), 20:00 PST = 09:30 IST (project reviews), 18:00 PST = 07:30 IST (urgent issues).
