Questions

What is the time difference between IST and CST?

Right now CST is 11 hours 30 minutes behind IST. The gap can change by an hour when daylight saving time starts or ends, because not every zone switches on the same date (or at all).

How do I convert IST to CST?

Subtract 11 hours 30 minutes from the IST time. For example, 12:00 PM IST is 12:30 AM CST.

Is it CST or CDT right now?

People often say “CST” all year, but during daylight saving time (mid-March to early November in the US) the zone is on CDT. It's CST right now. The converter above uses the correct one automatically.
