When the difference changes

India Standard Time and Eastern 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, 2027Eastern Time is 10 hours 30 minutes behind
  2. March 14, 2027 – November 7, 2027Eastern Time is 9 hours 30 minutes behind
  3. November 7, 2027 – onwardsEastern Time is 10 hours 30 minutes behind

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

India Standard Time

No clock changes

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

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.

Scheduling between the two

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

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.

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

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