How Kolkata Keeps Time
Kolkata keeps IST, UTC+5:30. The live clock normally synchronizes to the site time source and then applies the IANA rules for Kolkata; until synchronization succeeds, it uses the device clock as a fallback. Daylight-saving changes are applied only where that zone actually observes them.
Kolkata runs on the Asia/Kolkata zone in the IANA time zone database, which is UTC+5:30 right now. There is no daylight saving here, so that offset holds all year and the difference to other places only changes when they move their own clocks.
Kolkata is one of the places that sits 30 minutes off the hour rather than on it, so a straight “add five hours” conversion will always be 30 minutes wrong.
The sun rises in Kolkata at 5:37 am today and sets at 5:04 pm — 11 hours 27 minutes of daylight, with solar noon at 11:20 am. Those times come from the city’s coordinates (22.57, 88.36), so they shift a little every day of the year.
On the two solstices, Kolkata has about 13 hours 31 minutes of daylight in June and 10 hours 45 minutes in December. The difference is about 2 hours 46 minutes, which shows how strongly the local daylight cycle changes through the year.
The whole of India keeps one time, so the clock on this page is also the clock in New Delhi and in every other city listed below.
