Kolkata time zone and UTC offset
Kolkata runs on IST. That places it 5 hours 30 minutes ahead of UTC (UTC+05:30); in a calendar, server config or booking form, select Asia/Kolkata.
There is no daylight saving in Kolkata. UTC+05:30 applies all year, so the offset never moves on this side — only the other party's clock changes.
