Delhi is 3.5 hours ahead of Milan
Best overlap: 8:30 AM to 2:30 PM in Milan is 12:00 PM to 6:00 PM in Delhi.
Aim for 8:30 AM to 2:30 PM Milan time — that's 12:00 PM to 6:00 PM over in Delhi. With 6 hours of daily overlap, these two cities are an easy pairing; almost any reasonable hour works. Because Milan and Delhi don't both observe daylight saving, plan to re-check the overlap around March and November.
