About IST to PST
This page converts India Standard Time (IST) to Pacific Time (PT). Pick a date and time, and the answer appears at once. Below it, a table shows every hour of that day.
PT is 13 hours 30 minutes behind IST in winter, and 12 hours 30 minutes behind in summer, while the US is on daylight saving time. For example, 9:00 AM IST is 7:30 PM PST (previous day) in winter and 8:30 PM PDT (previous day) in summer.
IST is the time in Delhi, Mumbai, Bengaluru, Chennai, Hyderabad and Kolkata — all of India. PT is the time in Los Angeles, San Francisco, Seattle, Las Vegas and Vancouver.
The converter uses your browser's own time zone data, so daylight saving is handled for you — always right for the date you pick, in the past or the future.

Daylight saving time
India Standard Time (IST, UTC+5:30) has no daylight saving time. It stays the same all year.
Pacific Time uses PST (UTC−8) in winter and PDT (UTC−7) in summer. The US clocks go forward on the second Sunday of March and back on the first Sunday of November: March 8, 2026 to November 1, 2026, and March 14, 2027 to November 7, 2027.
Good to know
- PST or PT? PST is the winter time of the US West Coast; in summer it is PDT. People often say "PST" all year. The converter uses the right one for your date.
- IST is half an hour off the usual whole-hour zones (UTC+5:30), so a full hour on one side is half past the hour on the other.
- India is ahead. The US West Coast's evening is the next morning in India — check the day, not only the hour.
- Planning a meeting? Pick the date and time, then add the other cities of the people you meet with. Everyone's time shows in one list.
- The answer comes from your device's time zone data. Nothing is sent anywhere.
