Best Meeting Time: New York to Mumbai
🕐 Live Timezone Overlap: New York & Mumbai
New York and Mumbai sit 9.5 hours apart, with Mumbai ahead. That gap is large enough that a standard 9am–6pm working day in one city lands almost entirely outside business hours in the other. There is no overlap at all between the two cities' working hours. Any meeting requires at least one team to step outside normal hours, so agreeing early on who takes that burden is the first practical scheduling decision.
Time Difference: New York and Mumbai
Mumbai is currently 9.5 hours ahead of New York. The live offsets are New York UTC-4 and Mumbai UTC+5:30. New York observes daylight saving and Mumbai does not, so the offset shifts twice a year if both sides aren't already aligned.
Mumbai runs on IST, UTC+5:30, year-round and does not observe DST. New York currently observes EDT at UTC-4, shifting to EST at UTC-5 in winter. That means the gap between New York and Mumbai widens from 9.5 hours to 10.5 hours when New York moves back to standard time each autumn. Teams must update recurring calendar invites twice a year to account for New York's clock changes, even though Mumbai's clocks never move.
Best Times to Meet
With zero overlap between New York and Mumbai working hours, there is no in-hours window to draw from. The least disruptive compromise is typically an early morning slot in New York, such as 7am–8am ET, which lands at 4:30pm–5:30pm IST in Mumbai. That keeps Mumbai participants within or just beyond a standard 9am–6pm day. Note that Mumbai financial services teams sometimes work until 7pm IST, which can add a little flexibility on the Mumbai side for late-day calls.

Tips for Scheduling Across New York and Mumbai
- When New York shifts to EST each autumn, the New York–Mumbai gap widens to 10.5 hours; update recurring invites immediately.
- A 7am–8am ET slot is the least disruptive option, landing at 4:30pm–5:30pm IST for Mumbai participants.
- Mumbai's IST offset of UTC+5:30 is a non-integer, so standard scheduling tools sometimes display it incorrectly; verify the local time manually.
- Avoid scheduling across Diwali week; many Mumbai offices operate on reduced hours during that October–November period.
- New York's heaviest out-of-office stretch runs 24 December to 2 January; plan Mumbai-side deadlines accordingly.
Public Holidays and Working Weeks
Both New York and Mumbai follow a Monday-to-Friday working week. Cross-city meetings must account for both holiday calendars. In New York, Independence Day (4 July), Thanksgiving (fourth Thursday in November), and the Christmas period are the heaviest out-of-office stretches. In Mumbai, Diwali week in October or November brings reduced office hours across many firms. Checking both calendars before scheduling recurring calls saves repeated rescheduling.
