Notes
IST (India Standard Time, UTC+05:30) is 11h 30m ahead of CST (Central Time, UTC-06:00) when both are on standard time. Chicago (US Central) observes daylight saving (CDT, UTC-05:00) from mid-March to early November. During transition weeks the two regions may switch on different dates — for exact meeting times use the live converter below, which uses the IANA time-zone database.
Their 9:00–18:00 business hours do not overlap at all — one side has to take an early-morning or late-evening slot.
