About IST and CST
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 Central Time (CST/CDT) is used in Chicago, Dallas, Houston, Austin and Minneapolis. Clocks shift to CDT (daylight time) from March to November.
Time difference between IST and CST
CST is 11 hours 30 minutes behind IST in winter (January) and 10 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.
