Best Meeting Times: EST and IST

Standard 09:00–17:00 business hours do not overlap between Eastern Time and India Standard Time.

Standard 09:00–17:00 business hours do not overlap between New York and Kolkata. 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.

IST — India Standard Time
No DST — fixed offset
Year-round: UTC+05:30

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.

DST effect on this pair: EST observes DST; IST does not. During EST's DST period (2026-03-08 – 2026-11-01), the gap between the two zones narrows by 1 hour.
