IST (Indian Standard Time) is 13 hours 30 minutes ahead of PST (Pacific Standard Time). When it's 9 AM in California, it's 10:30 PM in India. During DST (Daylight Saving Time) in the US, the difference drops to 12 hours 30 minutes.
IST is UTC+5:30. Subtract 5 hours 30 minutes from IST to get UTC. Example: 11 AM IST = 5:30 AM UTC. Many international companies use UTC as their standard timezone for servers and meetings.
No. India does not observe DST. IST stays UTC+5:30 year-round. However, when scheduling with US/Europe partners, remember their clocks shift twice a year, changing your effective offset.
7 PM – 9 PM IST = 9 AM – 11 AM EST (US East Coast morning) or 6 AM – 8 AM PST (US West Coast early morning). Indian morning 9 AM – 11 AM IST = previous evening 11:30 PM – 1:30 AM US East Coast — usually too late for them.
India chose UTC+5:30 as a single time zone spanning the entire country (which actually spans about 2 hours of solar time). The half-hour offset was a compromise between the time of east and west India. Only a few zones use 30/45-minute offsets (India, Iran, Nepal, Afghanistan).
Yes. The converter uses your device's timezone data, which automatically adjusts for DST in regions that observe it (USA, Canada, Europe, Australia). India and most Asian countries don't observe DST.
