If your country observes daylight saving and India does not, expect the offset shown above to shift by an hour during your spring and autumn changeovers.
People moving between time zones rarely care about the abstract offset. They care whether the person on the other end is asleep, eating lunch, or about to start their day. Glance at the live clock above to read the Kolkata wall-clock time at this exact second, the same time anyone in town is looking at on their phone. The page updates every second without a refresh.
If you are arranging a meeting from somewhere else, the cleanest way is to pick a wall-clock time in Kolkata, then read what it translates to in your own city. That avoids the daylight-saving traps that catch out people who try to do the math with a fixed offset.

These places share Kolkata's clock down to the minute. If your meeting works in Kolkata, it works in any of these.
Kolkata sits in India, which uses Kolkata as its civil time. The current UTC offset is +05:30. If you are running a remote team with people on the ground in Kolkata, the practical question is which hours overlap with yours. Our meeting scheduler handles that across any combination of cities. For a quick mental model, the offset above is the difference from UTC, so add your own offset to read across.
Expats and freelancers use this page differently. If you have just moved to Kolkata, you probably want the public holiday list above so you know which Mondays you can sleep in and which Tuesdays the banks are closed. If you are billing clients from somewhere else, the offset matters less than knowing when their working day starts, which is roughly 3:00 your local time for a 9am start in Kolkata.
Travellers crossing into India usually want to know two things: how many hours to shift the watch, and whether daylight saving is about to make the answer wrong. Some countries observe DST and some do not. The clock above always shows the correct current offset, so if you check it the morning before your flight, you have the right number.
