IST (India Standard Time) is 11.5 hours ahead of CST (Central Standard Time). This means when it's 12:00 PM in Chicago (CST), it's 11:30 PM in Mumbai (IST).
The best time to call from CST to IST is during overlapping business hours. For CST callers, schedule between 9:00 AM - 12:00 PM CST to ensure both parties are within standard business hours.
The time difference may change during daylight saving transitions if one region observes DST while the other doesn't. Central Standard Time (UTC-6 (CST) / UTC-5 (CDT)) and India Standard Time (UTC+5:30) may have different DST schedules.
CST includes cities like Chicago. IST includes cities like Mumbai. Both time zones cover important business and cultural centers.
In 2025, DST in North America starts on March 9 at 2:00 AM and ends on November 2 at 2:00 AM. Other regions may have different DST schedules or not observe DST at all.
