Best overlap: 8:30 AM to 11:30 AM in Bengaluru is 3:00 PM to 6:00 PM in Auckland.
The best time to meet is 8:30 AM to 11:30 AM in Bengaluru, which is 3:00 PM to 6:00 PM in Auckland. Roughly 3 hours of shared hours means scheduling takes a little care — 8:30 AM in Bengaluru / 3:00 PM in Auckland is a safe default. Bear in mind Auckland shifts for daylight saving while Bengaluru stays fixed — recheck these hours after each clock change.
