About IST to CST Conversion

Converting time between IST and CST requires understanding their time zone offsets and any daylight saving time adjustments. IST (IST) operates at UTC+5, while CST (CST) is set to UTC-6. This means CST is 11.5 hours behind IST. Note that due to the time difference, the date may change. When it's 7:40 AM IST on February 4, 2026, it's 8:10 PM CST on February 3, 2026 in CST.
