# CST to IST converter

**Right now India is 11½ hours ahead of Central Time**: Chicago is on CST (UTC−6) and India is on IST (UTC+5:30). 9:00 AM Central Time is 8:30 PM in India.

CST and IST are both in effect today, so the strict and real-world answers match until March 14.

CST also stands for China Standard Time (UTC+8), used in [Beijing](https://wherora.com/time/beijing/) and across China, and for Cuba Standard Time. This page is about US Central Time. IST can also mean Irish Standard Time (UTC+1, Ireland’s summer time) or Israel Standard Time (UTC+2). This page is about India Standard Time.

## Where CST and IST are used

**CST** (Central Standard Time, Central Daylight Time in summer): [Chicago](https://wherora.com/time/chicago/), [Houston](https://wherora.com/time/houston/), [Dallas](https://wherora.com/time/dallas/), [Austin](https://wherora.com/time/austin/). **IST** (India Standard Time): [Mumbai](https://wherora.com/time/mumbai/), [New Delhi](https://wherora.com/time/new-delhi/), [Bengaluru](https://wherora.com/time/bengaluru/), Kolkata.

Central Time covers much of the middle of the US, including Illinois, Texas, Minnesota and Louisiana. Saskatchewan and Mexico City stay on UTC−6 all year, with no daylight saving, and since November 2026 Manitoba stays on UTC−5 all year.

All of India uses one time zone, IST (UTC+5:30), with no daylight saving. Sri Lanka uses the same offset.

## CST and IST: quick answers

### Is India ahead of or behind Central Time?

India is 11½ hours ahead of Central Time right now. That changes on Sunday, March 14, 2027, when it becomes 10½ hours ahead of Central Time.

### Does daylight saving change the Central Time–India time difference?

Yes. Only Central Time changes its clocks; India doesn’t use daylight saving time. Over the next year the difference is 11½ hours now, then 10½ hours from March 14. The converter above applies these changes for any date you pick.

### What’s the best time for a call between Central Time and India?

Normal 8 AM–5 PM working days don’t overlap. The least painful option is 7:00 AM–10:30 AM in Central Time, which is 6:30 PM–10:00 PM in India: early or late for one side, but inside 7 AM–10 PM for both. For a regular meeting, consider rotating the time (times for today; they move with daylight saving changes).
