Reverse of the SF-Bengaluru meeting slot. IST is 13.5 h ahead of PST (12.5 h ahead of PDT). If you're in Bengaluru and need to catch someone in Silicon Valley live, the practical window is 9-10:30 PM IST = 8:30-10 AM PT. Slack messages sent from India at end of day (7-8 PM IST) land at 6:30-7:30 AM PT and get read as SF folks start their day.
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.
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.
Time gap: PST is 13.5 hours behind IST (standard-time offsets — daylight-saving flips shift this by an hour twice a year in most northern-hemisphere zones).
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.
