About the time in Kolkata
Around 4,496,694 people live in Kolkata, and all of them keep the same civil time, so the reading above applies to the whole urban area — not just the city centre.
Kolkata runs on Asia/Kolkata, which puts the city UTC +5:30 from Coordinated Universal Time right now. The clock at the top of this page is not copied from your device: it is anchored to our reference timestamp and re-rendered every second against the IANA time zone database, so it stays right even when a laptop or phone has quietly drifted.
If you are coordinating from another country, the shortcut is the working window: a normal Kolkata day of 09:00–17:00 falls between 03:30–11:30 UTC. Convert your own hours into UTC once and you can tell at a glance whether someone there is likely to be at their desk.
