Frequently Asked Questions
What is the UTC to IST time difference?
IST (Indian Standard Time) is UTC+5:30. To convert UTC to IST, add 5 hours and 30 minutes. For example, 12:00 UTC is 17:30 IST. India does not observe Daylight Saving Time, so this offset is constant year-round.
Why is IST offset by 30 minutes?
India chose the UTC+5:30 offset as a compromise to cover its wide east-west span with a single timezone. The 30-minute offset places the timezone roughly at the 82.5°E meridian, which passes through Mirzapur in Uttar Pradesh.
Does India observe Daylight Saving Time?
No. India does not observe DST. IST remains UTC+5:30 throughout the entire year. This makes UTC-to-IST conversion simpler than converting to timezones that observe DST like EST/EDT or CET/CEST.
How do I convert IST to UTC?
To convert IST to UTC, subtract 5 hours and 30 minutes. For example, 14:00 IST is 08:30 UTC. Use our IST to UTC converter for instant, accurate conversions.

How It Works
This converter uses your browser's built-in Intl.DateTimeFormat API with the IANA timezone identifier Asia/Kolkata. IST is used across all of India and Sri Lanka. The +5:30 offset never changes because India does not observe Daylight Saving Time, making UTC-to-IST conversion deterministic: simply add 5 hours and 30 minutes to any UTC timestamp.
For developers working with distributed teams across India and the US or Europe, the most common conversion pairs are UTC-to-IST and IST-to-UTC. When scheduling meetings, note that the 30-minute offset means IST never aligns cleanly with hour-boundary timezones like EST (UTC-5) or CET (UTC+1).
Common UTC to IST Conversions
UTC 00:00 = IST 05:30 | UTC 06:00 = IST 11:30 | UTC 12:00 = IST 17:30 | UTC 18:00 = IST 23:30. Since there is no DST in India, these conversions are valid every day of the year.
