About CST and IST
US Central Time (CST/CDT) is used in Chicago, Dallas, Houston, Austin and Minneapolis. Clocks shift to CDT (daylight time) from March to November.
India Standard Time (IST) is used across all of India, including Mumbai, Delhi, Bengaluru, Chennai and Kolkata. India does not observe daylight saving time.
Time difference between CST and IST
IST is 11 hours 30 minutes ahead of CST in winter (January) and 10 hours 30 minutes ahead of CST 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.
Best hours for meetings
Scan the table for rows where both sides land inside working hours (9:00 to 18:00). Rows where one side is early morning or late evening are workable for a quick call; avoid rows where either side is in the middle of the night. To line up three or more cities at once, use the time zone converter and meeting planner.
