Q: What is the time difference between CST and IST?

IST is 11 hours 30 minutes ahead of US Central when both are on their standard designations (CST). The US side follows daylight saving (CDT in summer), while India uses IST year-round with no daylight saving—use the live converter for a specific date and time.

Q: Is it CST or CDT when converting to IST?

US Central uses CST in winter and CDT in summer. This page’s converter applies the correct offset for the time you choose. IST has no summer/winter change.

9:00 AM CST = 8:30 PM IST - 10:00 AM CST = 9:30 PM IST - 11:00 AM CST = 10:30 PM IST - 8:00 AM CST = 7:30 PM IST. When the US is on CDT, subtract one hour from each IST result (or use the converter).
