India Standard Time to US Eastern Time: live clocks, today's full conversion table, and the best hours to call. Daylight saving is handled automatically.
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.
Best hours for meetings
Scan the table for rows where both sides land inside working hours (9:00 to 18:00). Rows where one side is early morning or late evening are workable for a quick call; avoid rows where either side is in the middle of the night. To line up three or more cities at once, use the time zone converter and meeting planner.
