This EST to IST converter turns any time in Eastern Standard Time (EST) into India Standard Time (IST), using your device clock so daylight saving is applied automatically. IST is 10 hours 30 minutes ahead of EST when both zones are on standard time, and 9 hours 30 minutes ahead during the summer months when clocks have shifted. EST is UTC−5 (EDT: UTC−4); IST is UTC+5:30.
EST covers New York, Toronto, Miami; IST covers Mumbai, Delhi, Bengaluru. Because only EST observes daylight saving time, the difference is not constant through the year. The tables below show both cases, and the converter at the top always uses the rule in force on the date you pick.

Frequently asked questions
What is the time difference between EST and IST?
IST is 10 hours 30 minutes ahead of EST on standard time. During daylight saving the gap changes to 9 hours 30 minutes. That comes from the UTC offsets: EST is UTC−5 and IST is UTC+5:30. For example, 9 am EST = 7:30 pm IST, and in summer 9 am EST = 6:30 pm IST.
Is IST ahead of or behind EST?
IST is 10 hours 30 minutes ahead of EST, so when it is noon in EST it is 10:30 pm in IST. Ahead means the clock there already shows a later time; a call at 5 pm EST lands at 3:30 am IST.
Does EST or IST observe daylight saving time in 2026?
EST switches to EDT (UTC−4) on March 8 and back on November 1 in 2026. IST keeps UTC+5:30 all year. Between those dates the difference in the table above shifts by an hour, which is the usual cause of missed calls in spring and autumn.
What is the best time for a meeting between EST and IST?
Office hours (9 am to 5 pm) do not overlap at all with a 10 hours 30 minutes difference. The least painful options are early morning in EST or early evening in IST; for example 8 am EST = 6:30 pm IST and 6 pm EST = 4:30 am IST the next day. Rotate the inconvenient slot between the two sides for recurring calls.
Which cities use EST and IST?
EST (Eastern Standard Time) is used in New York, Toronto, Miami, Atlanta. IST (India Standard Time) is used in Mumbai, Delhi, Bengaluru, Kolkata. Some cities inside a zone skip daylight saving, noted in parentheses, so their offset matches only part of the year.
