Evening in Mumbai, New Delhi, Bangalore
In US Central (CDT)
8:30 AM – 11:30 AM

Avoid scheduling outside this window — one side will be in the middle of the night.

About IST and CST
India Standard Time (IST)
India Standard Time (IST) is the single time zone used across India and Sri Lanka. It is fixed at UTC+05:30 — 5 hours and 30 minutes ahead of Coordinated Universal Time. India does not observe daylight saving time, so IST stays the same year-round.
Central Standard Time (CST)
Central Standard Time (CST) is observed across major US cities including Chicago, Dallas, Houston, San Antonio, Austin, Memphis, and Nashville. CST is UTC-06:00 during standard time. From the second Sunday of March through the first Sunday of November, the region observes Central Daylight Time (CDT), shifting to UTC-05:00.
Daylight Saving Time
India Standard Time does not observe daylight saving — IST is fixed at UTC+05:30 all year. US Central Time switches to Central Daylight Time (CDT, UTC-05:00) on the second Sunday of March at 2:00 AM, and reverts to CST (UTC-06:00) on the first Sunday of November at 2:00 AM. This means the IST↔Central difference is 11 hours 30 minutes in winter (CST) and 10 hours 30 minutes in summer (CDT).
