About Kolkata
Kolkata, on the Hooghly River, was the capital of British India until 1911. India uses one time zone, IST (UTC+05:30), with no daylight saving, so the gap to Sweden is 4.5 hours in winter and 3.5 in summer. Because of the half-hour offset, meetings with Europe are often booked on the half hour.
There is no summer time in Kolkata; when Sweden changes its clocks, the difference changes by one hour.
