What is 1 AM IST in CST?

Does the answer change during the year?

Yes. India Standard Time and Central Time don't change their clocks on the same dates, so over the next 12 months:

• October 14 to October 31: 1 AM IST = 2:30 PM CST the previous day
• November 1 to March 13: 1 AM IST = 1:30 PM CST the previous day
• March 14 to October 13: 1 AM IST = 2:30 PM CST the previous day

Central Time switches between CST and CDT for daylight saving time; people often say CST all year.
