US East Coast teams in New York, Boston, and Washington DC with outsourcing partners or offices in India drive massive search volume on this pair. The 10.5-hour gap during EST (9.5 during EDT) means morning calls in the US catch Indian colleagues in the evening, making the overlap window narrow but usable.
When it's 12:00 PM in New York, it's 9:30 PM in Mumbai

Scheduling Tips
- Schedule meetings between 8:00-10:00 AM EST / 6:30-8:30 PM IST for the widest comfortable overlap.
- During EDT (March-November), the overlap improves -- 8:00 AM EDT is 5:30 PM IST, well within Indian work hours.
- For async workflows, have the India team post end-of-day updates by 6:00 PM IST so the US team sees them at 7:30 AM EST.
- Avoid scheduling past 10:30 AM EST -- that is 9:00 PM IST and pushes into personal time in India.
