1. Resolve 2026-11-02T03:03 in UTC to one UTC instant using date-specific IANA rules.
2. Source offset at that instant = UTC+0; target offset = UTC+5.5.
3. Offset difference = 330 − 0 = 330 minutes.

UTC to IST: quick answer
IST is UTC+5:30. To convert UTC to IST, add 5 hours 30 minutes. India does not use daylight saving time, so the offset is the same all year: 00:00 UTC is 05:30 IST, and 18:30 UTC is 00:00 IST the next day.
Offset: All year: +5 hours 30 minutes

- IST (India Standard Time) is the single time zone for all of India (IANA zone Asia/Kolkata).
- GMT and UTC give the same clock time for this conversion, so the same table works for GMT to IST.
- To convert IST back to UTC, subtract 5 hours 30 minutes.
Convert any UTC time in your head
- Add 5 hours to the UTC hour and 30 to the minutes.
- If the minutes reach 60 or more, take 60 away and add 1 to the hour.
- If the hour reaches 24 or more, take 24 away. The date in India is then one day later than the UTC date. Example: 21:25 UTC becomes 26:55, which is 02:55 IST the next day.
Worked examples
Times like these usually come from an announcement, a maintenance notice or a log file. Each IST value below is computed by the same time-zone code the converter uses.
| Example | UTC | IST |
|---|---|---|
| Webinar or exam slot | 14:00 | 19:30 (7:30 PM) |
| Short maintenance window | 13:00–13:15 | 18:30 (6:30 PM)–18:45 (6:45 PM) |
| Late-evening UTC announcement | 21:30 | 03:00 (3:00 AM) (next day) |
| A time with odd minutes | 21:25 | 02:55 (2:55 AM) (next day) |
| The midnight line in India | 18:30 | 00:00 (12:00 AM) (next day) |
| Start of the UTC day | 00:00 | 05:30 (5:30 AM) |
| Morning in the UK, afternoon in India | 07:00 | 12:30 (12:30 PM) |
| Evening in the UK, after midnight in India | 19:00 | 00:30 (12:30 AM) (next day) |
Mistakes that give the wrong answer
- "IST" is not always India
- Irish Standard Time (UTC+1, Ireland's summer time) and Israel Standard Time (UTC+2) use the same letters. If a notice comes from Ireland or Israel, "IST" does not mean India, and adding 5:30 to it is wrong.
- GMT is not the same as London time
- GMT and UTC give the same result here, but London uses BST (UTC+1) from late March to late October. In those months London is 4 hours 30 minutes behind India, not 5 hours 30. Use the India to London converter for UK clock times.
- A "Z" means UTC
- Timestamps such as 2026-10-18T21:30:00Z are already in UTC; the Z stands for zero offset. Add 5:30 to get IST, here 03:00 on 19 October.
- 12 AM and 12 PM
- 12:00 AM is midnight and 12:00 PM is noon. Writing times in 24-hour form (00:00, 12:00) avoids a 12-hour mistake when you add 5:30.
- Very old dates
- India has been on UTC+5:30 since 1945. The time-zone database records UTC+6:30 during the war years 1942–1945, so a fixed 5:30 rule is wrong for historical timestamps from that period.
UTC to IST questions
What is UTC time in India?
India does not keep UTC as its local time. It uses India Standard Time, which is UTC+5:30 everywhere in the country, so the time in India is always 5 hours 30 minutes ahead of UTC.
How do I convert UTC to IST?
Add 5 hours 30 minutes. If the result passes midnight, the date in India moves to the next day: 21:30 UTC is 03:00 IST the next day.
What is 7:00 AM UTC in IST?
7:00 AM UTC is 12:30 PM IST on the same day.
What is 7:00 PM UTC in IST?
7:00 PM UTC (19:00) is 12:30 AM IST, which is just after midnight on the following day in India.
Why is India 5 hours 30 minutes ahead and not a whole number of hours?
IST is the mean time of the 82°30′ E meridian, which passes near Mirzapur. The earth turns 15° an hour, and 82.5 ÷ 15 = 5.5 hours.
Does IST change for daylight saving time?
No. India does not use daylight saving time, so UTC to IST is +5:30 in every month. A difference that changes during the year comes from the other country's clock change, for example the UK or the US.

Enter the source-zone local date and time.
- Step 2
Choose or review the source and target zones.
- Step 3
Check the converted time, date and UTC offset difference.

Common questions
Does it account for daylight saving time?
Yes, according to the IANA time-zone data available in the browser runtime for the selected date.
Can DST transitions be ambiguous?
Yes. Repeated or skipped local times around a transition can require an authoritative time-zone check.
Does the offset stay the same all year?
Yes. Neither UTC nor India observes daylight saving time, so the offset between them is fixed all year.
