Stockholm is 3.5 hours behind Delhi

Best overlap: 12:00 PM to 6:00 PM in Delhi is 8:30 AM to 2:30 PM in Stockholm.

12:00 PM to 6:00 PM in Delhi is when Stockholm is also working, at 8:30 AM to 2:30 PM their time. The 3.5-hour gap barely gets in the way — you've got 6 hours of overlap, so pick whatever time fits the agenda. Heads up: because Stockholm changes its clocks and Delhi doesn't, the difference moves by an hour twice a year. Confirm the overlap around the DST switch.
