Delhi is 3.5 hours ahead of Stockholm

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

8:30 AM to 2:30 PM in Stockholm is when Delhi is also working, at 12:00 PM to 6:00 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. Just remember Stockholm changes its clocks for daylight saving and Delhi doesn't, so confirm the overlap whenever the seasons turn.
