IDT vs GST: what's the time gap?
GST is 1 hour ahead of IDT. In everyday terms, once you know the time on one side you just add 1 hour to get the other — so a call between Jerusalem and Dubai is always 1 hour apart.
What time is it in GST right now?
Right now the time in Gulf Standard Time (GST) is Monday, June 29, 2026 · 9:54:01 PM. It ticks every second, so you’re always looking at the live GST 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 1 hour gap is easy to see.
When is a good time to schedule a IDT to GST meeting?
For example, a 9:00 AM IDT meeting takes place at 10:00 AM GST. 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 GST?
The labels IDT and GST 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.
Why can you trust this IDT to GST 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 GST stays accurate for today and for any past or future date you type in.

Frequently asked questions
How many hours ahead of IDT is GST?
GST is 1 hour ahead of IDT — a fixed 1 hour difference, since both are fixed-offset labels.
What time is it in GST when it's 12:00 PM IDT?
When it's 12:00 PM (noon) IDT, it's 1:00 PM GST.
Do IDT or GST use daylight saving time?
Israel Daylight Time (IDT) observes daylight saving, alternating with IST; Gulf Standard Time (GST) is a fixed offset with no daylight saving.
Why might the real-world IDT–GST difference change during the year?
The labels IDT and GST 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 GST. Always check which label a region is currently using before you schedule.
