Live time conversion and hour-by-hour comparison
This page shows the live time conversion between Mumbai and New York. The hour-by-hour chart above makes it easy to find overlapping business hours for meetings or calls. Green highlights indicate standard business hours (9 AM – 5 PM) in each city.
Mumbai and New York are separated by 10.5 hours during EST and 9.5 hours during EDT. That half-hour component (from India's UTC+5:30 offset) consistently throws off scheduling. A '10 AM ET call' arrives in Mumbai at 8:30 PM IST, not 8 PM. The 30-minute difference is small but causes real confusion — always double-check Mumbai meeting times down to the minute.
The Mumbai-New York time connection drives one of the world's most important business relationships: US-India IT outsourcing. Millions of Indian tech professionals coordinate daily with New York-based clients. The standard rhythm: Indian teams work a shifted schedule (1-10 PM IST) to overlap with morning ET hours. This creates the famous 'follow-the-sun' model that enables near-continuous software development.
The BSE and NSE in Mumbai (9:15 AM to 3:30 PM IST) have zero overlap with NYSE hours (9:30 AM to 4 PM ET / 8 PM to 2:30 AM IST). Indian market movements set the tone for European sessions, which then influence New York — creating a global relay. US-based India-focused funds monitor Indian markets in their late evening and early morning hours.
The practical overlap: 8-10 AM ET catches 6:30-8:30 PM IST. This is the golden window for US-India calls — morning productivity in New York meets evening availability in Mumbai. For urgent matters, 7 AM ET = 5:30 PM IST (within Indian business hours). Avoid scheduling after 10 AM ET (8:30 PM IST) unless your Indian colleagues have explicitly agreed to late-evening availability.
