IST to UTC: IST is 5 hours 30 minutes ahead of UTC
India Standard Time is 5 hours 30 minutes ahead of Coordinated Universal Time, on every day of the year. It is 4:30 am IST in India and 11:00 pm UTC in UTC, which is already the previous day there.
Convert a specific time from IST to UTC
Pick any time and date to convert it both ways. The conversion runs in your browser against the real zone rules, so a date inside a daylight saving period gets that period's offset rather than today's.
What is the time difference between IST and UTC?
Coordinated Universal Time is 5 hours 30 minutes behind India Standard Time. To go from IST to UTC you subtract 5 hours 30 minutes. That gap holds on all 365 days of 2026: neither zone moves its clocks.

What are the best hours to schedule a call between IST and UTC?
2 hours of the standard 9:00 am to 5:00 pm working day line up in both zones, from 3:00 pm IST to 5:00 pm IST. In UTC that window reads 9:30 am to 11:30 am. Outside it, one side is either not yet at their desk or already gone.
| IST | UTC | Working hours | Note |
|---|---|---|---|
| 3:00 pm | 9:30 am | both sides | afternoon in India, mid morning in UTC |
| 4:00 pm | 10:30 am | both sides | afternoon in India, mid morning in UTC |
Does daylight saving change IST to UTC?
India Standard Time does not move its clocks at all, so its UTC+5:30 offset holds every day of the year.
Coordinated Universal Time does not move its clocks at all, so its UTC+0 offset holds every day of the year.
Is IST ahead of or behind UTC?
IST is ahead of UTC by 5 hours 30 minutes: when it is 12:00 pm in India, it is 6:30 am in UTC. Neither India Standard Time nor Coordinated Universal Time observes daylight saving, so the abbreviations never change and the gap between them is fixed.
India Standard Time covers the whole of India on a single half hour offset. Coordinated Universal Time covers the reference all other zones are measured against. The identifiers behind them are Asia/Kolkata and Etc/UTC, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
