Frequently Asked Questions
What is the IST to UTC offset?
Indian Standard Time (IST) is UTC+5:30 year-round. India does not observe Daylight Saving Time, so the offset never changes.
Why is India's timezone offset 30 minutes?
India chose UTC+5:30 as a compromise to serve the entire country with a single timezone. The half-hour offset better centers the timezone across India's geographic span from Gujarat to Arunachal Pradesh.
How do I convert IST to EST?
IST is 10.5 hours ahead of EST (or 9.5 hours ahead of EDT during summer). For example, 9 PM IST is 10:30 AM EST. Use this converter to get exact results for any date.
