EDT to IST Time Converter
India Standard Time (IST) is currently 9 hours 30 minutes ahead of Eastern Daylight Time (EDT). EDT is UTC-4 and IST is UTC+5:30. The table below converts every hour of the day between the two, and the call planner shows where working hours line up.
Best Time for a Call
There is no overlap between 9:00 AM and 5:00 PM office hours in these two zones. Stretching to early mornings and evenings, the workable window runs from 7:00 AM to 11:30 AM in EDT, which is 4:30 PM to 9:00 PM in IST. One side ends up outside normal hours, so alternating who takes the awkward slot is a fair way to handle recurring calls.
