India Standard Time (IST)

India Standard Time is the single time zone used across the whole of India, fixed at UTC+5:30. Its IANA identifier is Asia/Kolkata. India has not observed daylight saving time since 1945, so IST reads the same on every date of the year — which makes it unusually simple on its own and unusually awkward in conversion, because almost every country it trades with does shift.

The offset is anchored to the 82.5°E meridian, which sits half an hour off a whole-hour boundary. That is why IST conversions usually land on :30 rather than :00, and why a single Indian hour straddles two clock hours nearly everywhere else.

How to convert IST to other time zones

Subtract 5 hours 30 minutes to reach UTC, then apply the target zone's offset for the date in question. The date matters: most zones move by an hour for part of the year, and the switch dates differ by country. The converter above does this from the IANA database rather than a fixed offset.

IST to EST

India is 10 hours 30 minutes ahead of Eastern Standard Time and 9 hours 30 minutes ahead of Eastern Daylight Time. US clocks move forward on the second Sunday in March and back on the first Sunday in November. Open the IST to EST converter or convert EST to IST.

IST to PST

India is 13 hours 30 minutes ahead of Pacific Standard Time and 12 hours 30 minutes ahead of Pacific Daylight Time — the widest gap between India and the continental US. IST to PST · PST to IST.

IST to GMT

India is 5 hours 30 minutes ahead of Greenwich Mean Time, and that never changes, because neither GMT nor IST observes daylight saving. The United Kingdom, however, moves to British Summer Time from late March to late October, when the gap becomes 4 hours 30 minutes. IST to GMT · IST to BST.

Frequently Asked Questions

What is IST?

IST on this site means India Standard Time, the single time zone used across all of India, fixed at UTC+5:30. The abbreviation is ambiguous — it also stands for Irish Standard Time (UTC+1) and Israel Standard Time (UTC+2) — so every conversion here refers to India.

What is the current time in India?

The live clock on this page shows India Standard Time to the second. Mumbai, Delhi, Bengaluru, Chennai, Kolkata and Hyderabad all read the same time, because India uses one zone for the whole country.

What is IST in UTC?

India Standard Time is UTC+5:30. To convert IST to UTC, subtract 5 hours 30 minutes. Because neither IST nor UTC observes daylight saving, this conversion is the same on every date of the year.

How many hours ahead is India from New York?

India is 10 hours 30 minutes ahead of New York during US Eastern Standard Time, and 9 hours 30 minutes ahead during Eastern Daylight Time (mid-March to early November). India never changes its clocks, so the whole change comes from the New York side.

How many hours ahead is India from London?

India is 5 hours 30 minutes ahead of London in winter, when the UK is on GMT, and 4 hours 30 minutes ahead in summer, when the UK is on British Summer Time.

Does India observe daylight saving time?

No. India has kept a single UTC+5:30 offset since 1945 with no daylight saving. Any seasonal change in the gap between India and another country comes entirely from the other side.

What is the difference between IST and EST?

IST is UTC+5:30 and EST is UTC−5:00, a difference of 10 hours 30 minutes. Strictly, EST is the winter half of US Eastern Time; from mid-March to early November the same cities run on EDT (UTC−4:00) and the gap narrows to 9 hours 30 minutes.

What is the difference between IST and PST?

IST is 13 hours 30 minutes ahead of Pacific Standard Time, and 12 hours 30 minutes ahead during Pacific Daylight Time. It is the widest gap between India and the continental United States, and a 9–6 Indian working day never overlaps a 9–5 Californian one.

How do I convert IST to local time?

Enter the date and the IST time in the converter above and pick your zone or city. The date matters: most zones shift by an hour for daylight saving at some point in the year, so a conversion without a date is only right for part of it.

What time zone does India use?

India uses India Standard Time, IANA identifier Asia/Kolkata, at UTC+5:30. It is one zone for the entire country, from Gujarat to Arunachal Pradesh, despite India spanning roughly 30 degrees of longitude.
