UTC to IST: quick answer
To convert Coordinated Universal Time (UTC) to Indian Standard Time (IST), add 5 hours and 30 minutes. For example, 9:00 AM UTC is 2:30 PM IST on the same date. UTC is fixed at UTC+00:00 and IST is fixed at UTC+05:30, so this conversion does not change for daylight saving time.
How to convert UTC to IST
IST = UTC + 5 hours 30 minutes
- Start with the UTC date and time.
- Add five hours.
- Add another 30 minutes.
- If the result reaches or passes midnight, move to the next calendar date.
Example: 4:45 PM UTC + 5 hours 30 minutes = 10:15 PM IST. A late UTC time may move into the following date: 8:00 PM UTC on July 19 is 1:30 AM IST on July 20.
Common UTC to IST conversions
| UTC | IST | Date note |
|---|---|---|
| 12:00 AM | 5:30 AM | Same date |
| 6:00 AM | 11:30 AM | Same date |
| 9:00 AM | 2:30 PM | Same date |
| 12:00 PM | 5:30 PM | Same date |
| 3:00 PM | 8:30 PM | Same date |
| 6:00 PM | 11:30 PM | Same date |
| 7:00 PM | 12:30 AM | Next date |
| 11:00 PM | 4:30 AM | Next date |

When the calendar date changes
UTC times from 6:30 PM through 11:59 PM convert to the next calendar date in IST. At exactly 6:30 PM UTC, the IST result is 12:00 AM the following day. This date rollover matters for deployment windows, flight schedules, live events, interviews and calendar invitations.
UTC to IST for timestamps and developers
UTC is commonly used for server logs, databases, APIs and distributed systems. Convert the timestamp as an exact instant, then display it with the Asia/Kolkata time-zone identifier. For example, 2026-07-19T18:30:00Z is 2026-07-20 00:00:00 in IST.
Implementation note: store event times in UTC when appropriate, retain the original offset when it has legal or business meaning, and use a maintained time-zone library for display. Do not relabel a UTC clock value as IST without applying the +05:30 offset.
Best UTC to IST meeting times
A practical UTC meeting window is 7:30 AM–12:30 PM UTC, which is 1:00 PM–6:00 PM IST. The best time still depends on each participant’s working hours. Use the planner above when a third location is involved.
Formula, precision and verification
The calculator applies an exact offset of +330 minutes from UTC to IST. It converts the date and time first, then formats the result; it does not round the offset. Verification cases include midnight, noon, the 6:30 PM UTC date boundary, month-end and year-end rollover, and reciprocal UTC → IST → UTC checks.
UTC is the international reference time scale. India’s national time laboratory disseminates Indian Standard Time at UTC+05:30. Neither UTC nor IST uses a seasonal daylight-saving adjustment.
Frequently asked questions
What is the time difference between UTC and IST?
IST is exactly 5 hours and 30 minutes ahead of UTC throughout the year.
What is 9:00 AM UTC in IST?
9:00 AM UTC is 2:30 PM IST on the same calendar date.
What is 8:00 PM UTC in IST?
8:00 PM UTC is 1:30 AM IST on the following calendar date.
Does UTC to IST change for daylight saving time?
No. UTC stays at +00:00 and India Standard Time stays at +05:30, so the difference is fixed.
Is UTC the same as GMT for this conversion?
UTC and GMT both use an offset of +00:00 for ordinary civil-time conversion, so they produce the same clock result when converting to IST. They are not identical technical standards.
