IDT vs HST: what's the time gap?
HST is 13 hours behind IDT. In everyday terms, once you know the time on one side you just subtract 13 hours to get the other — so a call between Jerusalem and Honolulu is always 13 hours apart.
What's the current time in HST?
Right now the time in Hawaii Standard Time (HST) is Monday, June 29, 2026 · 7:54:01 AM. It ticks every second, so you’re always looking at the live HST clock.
And what time is it in IDT?
And in Israel Daylight Time (IDT), it’s currently Monday, June 29, 2026 · 8:54:01 PM. Compare the two and the 13 hours gap is easy to see.
When is a good time to schedule a IDT to HST meeting?
For example, a 9:00 AM IDT meeting takes place at 8:00 PM HST (−1 day). 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 IDT–HST difference?
The labels IDT and HST are fixed offsets, so the result on this page is always exact. One side switches between standard and summer time while the other stays put, so the real-world gap can shift by an hour for part of the year. It's worth checking which label a region is actually using before you lock in a time.
How accurate is this IDT to HST conversion?
We don’t guess. IDT and HST 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.

Frequently asked questions
How many hours behind IDT is HST?
HST is 13 hours behind IDT — a fixed 13 hours difference, since both are fixed-offset labels.
What time is it in HST when it's 12:00 PM IDT?
When it's 12:00 PM (noon) IDT, it's 11:00 PM HST the previous day.
Do IDT or HST use daylight saving time?
Israel Daylight Time (IDT) observes daylight saving, alternating with IST; Hawaii Standard Time (HST) is a fixed offset with no daylight saving.
Why might the real-world IDT–HST difference change during the year?
The labels IDT and HST are fixed offsets, so this converter is always exact. But Israel Daylight Time's region switches between standard and summer time, so for part of the year you may actually want IST to HST. Always check which label a region is currently using before you schedule.
