India Standard Time (IST) is 10 hours 30 minutes ahead of Central Time (CST).

Here is every hour of the day in IST and the same moment in CST.

The green rows are the hours when both zones are inside 9 AM to 5 PM. The row marked Now is the hour it is in India Standard Time right now.

A team split between India and CT is never at work together between 9 AM and 5 PM.

Taking 9 AM to 5 PM on each clock as the working day, the two zones are never at work at the same moment, so a meeting means an early start or a late finish on one side.

A team spread across two time zones has fewer chances to notice someone drifting away. TeamPredict reads public LinkedIn signals to flag resignation risk early, wherever people work.

The gap between IST and CST moves between 10 hours 30 minutes and 11 hours 30 minutes during the year.

India Standard Time never changes its clocks, but the United States does, so the gap moves by an hour each time Central Time moves.

These are the clock changes of both zones in 2026 and 2027.

IST stands for India Standard Time and CST for Central Time on this page.

IST on this page means India Standard Time, UTC+5:30, which India keeps all year. The same letters are also used for Irish Standard Time and Israel Standard Time.

Central Time is CST (UTC−6) in winter and CDT (UTC−5) in summer. People write CST all year, and this page does too; the clock reads CDT right now. It moves its clocks forward at 2:00 AM on the second Sunday in March and back at 2:00 AM on the first Sunday in November.
