MDT vs IDT: what's the time gap?

Right now the time in Israel Daylight Time (IDT) is Monday, June 29, 2026 · 8:53:56 PM. It ticks every second, so you’re always looking at the live IDT clock.
And what time is it in MDT?
And in Mountain Daylight Time (MDT), it’s currently Monday, June 29, 2026 · 11:53:56 AM. Compare the two and the 9 hours gap is easy to see.
What's the best time for a MDT–IDT call?

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 MDT–IDT difference?
The labels MDT 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 9 hours gap usually holds steady right through the year.
How accurate is this MDT to IDT conversion?
We don’t guess. MDT 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.
