About EST to IST
EST to IST is one of the most-searched time zone conversions worldwide, driven largely by the volume of business coordination between US East Coast companies and teams in India.
A note on daylight saving
Unlike EST-to-PST, this gap genuinely changes across the year: India does not observe daylight saving at all, while the US does — so the difference is 10.5 hours in winter (EST) and 9.5 hours in summer (EDT), even though India's clocks never move.
Common questions
How many hours is EST to IST?
10.5 hours in winter (when the US is on standard EST), and 9.5 hours in summer (when the US shifts to EDT) — India's clocks don't change, so the gap shrinks in the US summer.
Why is the time difference not a round number of hours?
India Standard Time is offset by 5 hours and 30 minutes from UTC, a deliberate half-hour offset rather than a whole-hour one, which is why conversions to and from IST rarely land on an even hour.
What is a good meeting time between EST and IST?
Early morning EST (around 7-9 AM) typically lands in the evening in India (roughly 5:30-7:30 PM IST), a commonly used overlap window for US-India teams.
