Why this conversion matters

The reverse of EST to IST — India teams coordinating with US East Coast counterparts. The same overlap window applies: 7-8:30 PM IST corresponds to 8:30-10 AM EST. India teams typically stretch evening hours for this pattern; the alternative is 8-9 AM IST = 10:30-11:30 PM the previous day in New York, only viable for emergencies. When EST becomes EDT in March, IST is 9.5 hours ahead and the overlap shifts an hour earlier in IST. India-based teams handling US East Coast accounts should expect their working window to include evening hours during the US standard-time months.

When is the best time to schedule a meeting between Mumbai and New York?

The working-hours overlap (9 AM-5 PM on both sides) is there is no direct 9-5 overlap — schedule outside standard business hours on at least one side. Joint calls require one side to take an early-morning or late-evening slot; many teams alternate which side absorbs the off-hours.
