IDT vs CST: what's the time gap?
CST is 9 hours behind IDT. In everyday terms, once you know the time on one side you just subtract 9 hours to get the other — so a call between Jerusalem and Chicago is always 9 hours apart.
What time is it in CST right now?
Right now the time in Central Standard Time (CST) is Monday, June 29, 2026 · 11:54:01 AM. It ticks every second, so you’re always looking at the live CST clock.
What time is it in IDT right now?
And in Israel Daylight Time (IDT), it’s currently Monday, June 29, 2026 · 8:54:01 PM. Compare the two and the 9 hours gap is easy to see.
Planning a meeting across IDT and CST?
For example, a 9:00 AM IDT meeting takes place at 12:00 AM CST. The trick is to aim for a slot that lands inside normal working hours on both sides. Once you’ve found a time, hit Share on the converter to copy a link with the time built in — easy to send to a colleague. Juggling three or more zones? The meeting planner highlights the hours that overlap for everyone.
How does daylight saving affect IDT to CST?
The labels IDT and CST are fixed offsets, so the result on this page is always exact. Both regions move their clocks for daylight saving on roughly the same weekends, so the 9 hours gap usually holds steady right through the year.
Why can you trust this IDT to CST converter?
Every conversion here is calculated from the IANA time zone database — the same source your phone, computer, and browser rely on. Plenty of tools hard-code a single offset, which quietly goes wrong whenever a region changes its rules or flips for daylight saving. We follow the real rules instead, so IDT to CST stays accurate for today and for any past or future date you type in.

Why might the real-world IDT–CST difference change during the year?
