The best time for a call

A 9-to-5 day in New York and one in Mumbai don’t overlap at all, so somebody has to stretch. The fairest one-hour slot is usually 8:00 AM in New York, which is 5:30 PM in Mumbai. It asks New York to start about an hour early and Mumbai to stay about an hour and a half late.

India is on a half-hour offset (UTC+5:30) and doesn’t change its clocks, so the gap is 9½ hours during the US summer and 10½ in winter. Conversions rarely land on the hour, which is worth remembering when someone types a time into an invite by hand. The whole country uses this one time, so the figures hold for Delhi, Bengaluru, Chennai and Hyderabad too.

Many Indian teams that work with US clients keep shifted hours, starting around midday and finishing late in the evening. Ask about their actual schedule before assuming nobody is around.
