CEST vs IDT: what's the time gap?
IDT is 1 hour ahead of CEST. In everyday terms, once you know the time on one side you just add 1 hour to get the other — so a call between Paris and Jerusalem is always 1 hour apart.
What's the current time in IDT?
Right now the time in Israel Daylight Time (IDT) is Monday, June 29, 2026 · 8:53:59 PM. It ticks every second, so you’re always looking at the live IDT clock.
And what time is it in CEST?
And in Central European Summer Time (CEST), it’s currently Monday, June 29, 2026 · 7:53:59 PM. Compare the two and the 1 hour gap is easy to see.
Planning a meeting across CEST and IDT?
For example, a 9:00 AM CEST meeting takes place at 10:00 AM IDT. 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.
Does daylight saving time change the CEST–IDT difference?
The labels CEST and IDT 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 1 hour gap usually holds steady right through the year.
How accurate is this CEST to IDT conversion?
We don’t guess. CEST and IDT times are worked out from the official IANA time zone database, the trusted standard that operating systems use worldwide. Because daylight-saving rules and regional offsets do change over time, we track those updates rather than relying on a fixed number — which is exactly where many converters slip up.

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