Green rows = business hours overlap (9:00 AM – 6:00 PM PST)
Pacific Standard Time (PST) is UTC-8. California, Oregon, Washington, and Nevada observe PDT (UTC-7) from the second Sunday in March to the first Sunday in November.
India Standard Time (IST) is UTC+5:30. India never observes daylight saving time — IST is fixed year-round.
The 13.5-hour gap makes US West Coast to India scheduling challenging. The only practical overlap is early morning PST / evening IST: 6:30–9:00 AM PST = 8:00–10:30 PM IST. During PDT (summer), the gap shrinks to 12.5h: 7:00 AM PDT = 7:30 PM IST.
India's tech hubs (Bangalore, Hyderabad, Pune) heavily serve US West Coast clients — this is one of the most-used international time conversions in the global IT industry.
When the US enters PDT (March–November), PST clocks move forward 1 hour → gap becomes 12.5h. India stays at UTC+5:30 all year.
PST (UTC-8) is 13 hours and 30 minutes behind IST (UTC+5:30) during US standard time. When the US observes PDT (UTC-7, March–November), the gap narrows to 12 hours and 30 minutes. India does not observe daylight saving time — IST remains UTC+5:30 year-round.
When it is 9:00 AM PST (UTC-8), it is 10:30 PM IST the same day. During PDT (UTC-7), 9:00 AM PDT = 9:30 PM IST. India is always ahead — the US West Coast morning corresponds to India evening.
The best overlap is 6:30–9:00 AM PST, which corresponds to 8:00–10:30 PM IST. During PDT (summer), 7:00–9:00 AM PDT = 7:30–9:30 PM IST. This requires India participants to be available in the evening. Avoid calling India before 6:00 AM PST (before 7:30 PM IST).
PST (UTC-8) is exactly 13 hours and 30 minutes (13.5 hours) behind IST (UTC+5:30). It is not a whole-hour difference because India uses a UTC+5:30 offset. During US daylight saving time (PDT, UTC-7), the difference is 12 hours and 30 minutes (12.5 hours).
No. India does not observe daylight saving time. India Standard Time (IST) is UTC+5:30 year-round. This means the PST–IST gap changes only when the US switches between PST and PDT — not when India changes, because India never does.
