Current Time in India
India Standard Time (IST) — UTC+5:30, used uniformly across the entire country with no daylight saving time.
Indian Time Across Major Cities
All Indian cities share the exact same time — India Standard Time (IST). Unlike large countries such as the US or Russia, India uses a single time zone nationwide.
Indian Time Difference to Major Cities
| City | Winter Difference | Summer Difference |
|---|---|---|
| London | India is 5h 30m ahead | India is 4h 30m ahead |
| New York | India is 10h 30m ahead | India is 9h 30m ahead |
| Dubai | India is 1h 30m ahead | India is 1h 30m ahead |
| Singapore | India is 2h 30m behind | India is 2h 30m behind |
| Tokyo | India is 3h 30m behind | India is 3h 30m behind |
| Sydney | India is 4h 30m behind | India is 5h 30m behind |
India does not observe daylight saving time, so any seasonal change in the difference is caused entirely by the other country's DST transition, not India's.
About India Standard Time (IST)
India Standard Time is the single time zone observed across the entire Republic of India, set at UTC+5:30 — five hours and thirty minutes ahead of Coordinated Universal Time. It is one of the few time zones in the world that uses a half-hour offset rather than a full hour, alongside places like Iran, Afghanistan, and parts of Australia.
The unusual half-hour offset exists because India spans approximately 30 degrees of longitude — wide enough to naturally justify two separate time zones. Rather than splitting the country, India adopted a single compromise time in 1947, balancing the needs of the easternmost region (closer to UTC+6) and the westernmost region (closer to UTC+5).
India has never observed daylight saving time. This means IST remains fixed at UTC+5:30 throughout the entire calendar year — a useful, predictable reference point when scheduling meetings or calls with Indian colleagues, clients, or family.
India Time — Frequently Asked Questions
India follows a single national time zone called India Standard Time (IST), which is UTC+5:30. This applies across the entire country — from Mumbai to Kolkata, Delhi to Chennai — regardless of the time zone widget above showing the live current time in India.
IST stands for India Standard Time, fixed at UTC+5:30 — five hours and thirty minutes ahead of Coordinated Universal Time. It is one of only a handful of time zones in the world that uses a half-hour offset instead of a full hour. IST was officially adopted in 1947 and applies uniformly across all of India.
India spans roughly 30 degrees of longitude — wide enough to naturally cover two time zones. Instead of splitting the country, India adopted a single time zone at UTC+5:30, a compromise between the calculations for Mumbai in the west and Kolkata in the east. This half-hour offset (UTC+5:30 rather than UTC+5 or UTC+6) balances daylight hours across the country.
No. India does not observe daylight saving time (DST). Indian Standard Time remains fixed at UTC+5:30 throughout the entire year, with no seasonal clock changes. This makes calculating the time difference between India and other countries simpler in some ways, since only the other country's DST status changes the gap.
India Standard Time (UTC+5:30) is 10 hours and 30 minutes ahead of US Eastern Time (EST, UTC-5) in winter, and 9 hours 30 minutes ahead during Eastern Daylight Time (EDT, UTC-4) in summer. For US Pacific Time, the gap is 13 hours 30 minutes in winter and 12 hours 30 minutes in summer.
India Standard Time is 5 hours 30 minutes ahead of GMT (UK winter time) and 4 hours 30 minutes ahead of BST (UK summer time). When it is 12:00 PM in London during winter, it is 5:30 PM in India.
India Standard Time (UTC+5:30) is 1 hour 30 minutes ahead of Gulf Standard Time in Dubai (UTC+4). When it is 10:00 AM in Dubai, it is 11:30 AM in India. This offset stays constant year-round since neither India nor the UAE observes daylight saving time.
Both Mumbai and Delhi use India Standard Time (IST, UTC+5:30) — the single time zone used across all of India. There is no time difference between any two cities within India, regardless of how far apart they are geographically.
