PST to IST Converter – Convert Pacific Time to Indian Time

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).

To convert PST to IST:

1. Winter (PST): Add 13.5 hours to PST (November-March)
2. 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.

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.

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.

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.

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.

Best practices for US West Coast-India scheduling:

1. Optimal window: 18:00-22:00 PST (07:30-11:30 IST next day or 06:30-10:30 IST during PDT)
2. Always specify both local times in meeting invites (e.g., "19:00 PST / 08:30 IST")
3. Account for DST transitions: US changes in March/November, India never changes
4. Use correct abbreviations: 'PST' for November-March, 'PDT' for March-November
5. 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).
