See the live UTC time next to the current time in India, check today's real offset, and roll through any UTC time to find the matching IST time — including when the two zones fall on different dates.

Coordinated Universal Time (UTC) is the world's time standard: it never shifts for seasons and every other zone is described as an offset from it. India Standard Time (IST) is the clock used in India. Converting UTC to IST means adding that offset to the UTC reading.
India Standard Time covers the whole country from a single meridian near Mirzapur (82.5° E), which is why the offset lands on a half hour rather than a full hour.
Take the UTC time, apply the current IST offset shown in the live panel above, and roll the date forward or back if the result crosses midnight. The interactive roller does all three steps for you: the left drum is UTC, the right drum is IST, and a day badge appears whenever the local date differs.
IST has no daylight saving changes, so the offset to UTC is stable all year. It is still calculated live from the Asia/Kolkata IANA database rather than hard-coded.
The reference table below the tool lists every UTC half hour against the matching IST time for today, so you can copy a conversion without touching the roller.
India does not use daylight saving time. IST stays at UTC +05:30 every day of the year, so a conversion you learn in January still works in July.
