When the difference changes

Eastern Time and India Standard Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:

  1. Now – March 14, 2027India Standard Time is 10 hours 30 minutes ahead
  2. March 14, 2027 – November 7, 2027India Standard Time is 9 hours 30 minutes ahead
  3. November 7, 2027 – onwardsIndia Standard Time is 10 hours 30 minutes ahead

Periods shorter than a day are not listed. Each zone changes at its own local time, so on a date when both move there are a few hours when the gap is briefly something else.

Daylight saving

Eastern Time

Sunday, March 14, 2027

Clocks go forward one hour — 2:00 am becomes 3:00 am local time, and the zone is on EDT after that.

India Standard Time

No clock changes

India Standard Time stays on IST all year, so its offset from UTC never moves.

Scheduling between the two

There is no overlap between a nine-to-six working day in New York and one in New Delhi — the gap is too wide. A call has to sit early or late for one side. Early morning in New York is the usual compromise, since that is late afternoon or evening in New Delhi.

A note on IST: it can also mean Israel Standard Time (UTC+2) and Irish Standard Time (UTC+1). This page means India Standard Time, which is what almost all searches for IST want.

Eastern Time (EST) is used in Toronto, Atlanta, Miami, Detroit and most of the US east coast

India Standard Time (IST) is used in all of India and Sri Lanka, on a single UTC+5:30 offset with no daylight saving
