EST to IST converter
IST is 9 hours 30 minutes ahead of EST for most of the year. The gap is different for part of the year, because only one side changes its clocks: in 2026 that is 1 January to 7 March (10 hours 30 minutes) and 1 November to 31 December (10 hours 30 minutes). If you schedule something in that period, check the date.

About the two time zones
Eastern Time (EST/EDT). Used in: New York, Toronto, Miami, Atlanta, Boston, Washington DC. Clocks go forward on the second Sunday in March and back on the first Sunday in November.
People write EST all year round, even in summer when the clocks actually say EDT. This tool treats EST, EDT and ET as the same thing: the current time in New York.
India Standard Time (IST). Used in: Delhi, Mumbai, Bengaluru, Kolkata, Chennai. No daylight saving: the offset is the same all year.
India is UTC+5:30, so conversions often end in :30. IST can also mean Irish Standard Time or Israel Standard Time; here it means India.
