EST to IST converter
Convert EST to IST for New York ↔ India. It is a 9.5–10.5 hour gap with almost no daytime overlap — the planner shows the one window that works.
How EST to IST actually works
India Standard Time is UTC+5:30 and has no daylight saving. Eastern Time is UTC−5 (EST) in winter and UTC−4 (EDT) in summer. So New York to India is 10 hours 30 minutes from roughly November to March, and 9 hours 30 minutes from March to November. The offset never lands on a whole hour because of India's half-hour zone.
This is one of the hardest common pairs. Nine to ten hours means one side's working day starts as the other's ends. The planner above keeps New York and Mumbai on one UTC minute so you can see exactly where — and whether — the days touch.
The only realistic overlap
- Strict 09:00–17:00 on both sides: effectively no shared hours.
- Practical window: 07:30–09:00 New York / 18:00–19:30 India — early for New York, late for India.
- In summer (EDT) the same window shifts an hour earlier for India.
If a live call is unavoidable, keep it to 30 minutes at that edge and rotate who takes the awkward slot. Everything else works better as async updates — the same pattern covered in Asia–Europe meeting times.
Convert a specific time
- The planner already has New York and Mumbai loaded.
- Drag either bar — both rows stay on the same UTC moment, and the India row will often show “+1 day”.
- Copy the invite so the date is unambiguous on both sides.

What is the time difference between EST and IST?

India Standard Time is UTC+5:30, so every conversion to IST lands on the half hour.
