Why this conversion matters

The Eastern Time to India Standard Time conversion underpins much of the US-India IT services relationship that supports enterprise back-office work. With New York 10.5 hours behind Mumbai, the practical scheduling window for joint calls sits between 8:30-10 AM EST (7-8:30 PM IST) — early morning for New York, evening for Mumbai. India does not observe daylight saving time, but the US does, so from mid-March through early November the offset shifts to 9.5 hours when EST becomes EDT. Plan for that twice-yearly transition when scheduling recurring meetings; calendar invites in IST stay constant year-round while the EST/EDT side moves by an hour.
