About IST and EST
India Standard Time (IST) is used across all of India, including Mumbai, Delhi, Bengaluru, Chennai and Kolkata. India does not observe daylight saving time.
US Eastern Time (EST/EDT) is used in New York, Washington DC, Boston, Atlanta, Miami and Toronto. Clocks shift to EDT (daylight time) from March to November.
Time difference between IST and EST
EST is 10 hours 30 minutes behind IST in winter (January) and 9 hours 30 minutes behind IST in summer (July), because of daylight saving changes. The clocks and table above are computed live from the official IANA time zone database in your browser, so daylight saving transitions are always already included.
