Best Meeting Times: IST and EST
Standard 09:00–17:00 business hours do not overlap between India Standard Time and Eastern Time.
Standard 09:00–17:00 business hours do not overlap between Kolkata and New York. Consider a standing 08:00 call for the earlier zone, which lands in the evening for the later zone.
For zero-overlap corridors, we recommend the Meeting Planner's rotation-fairness feature to distribute meeting burden equitably.
Working Across IST and EST
Daylight Saving Time: IST and EST
India does not observe Daylight Saving Time. IST (UTC+5:30) is fixed year-round. India's unusual 30-minute offset was standardized in 1906 and applies to the entire country despite spanning nearly 30 degrees of longitude.
The US observes Daylight Saving Time. Clocks spring forward 1 hour on the second Sunday in March and fall back on the first Sunday in November. During EDT (UTC−4), the gap to IST narrows by 1 hour.
