What is the time difference between IDT and SAST?
SAST is 1 hour behind IDT. In everyday terms, once you know the time on one side you just subtract 1 hour to get the other — so a call between Jerusalem and Johannesburg is always 1 hour apart.
What's the current time in SAST?
Right now the time in South Africa Standard Time (SAST) is Monday, June 29, 2026 · 7:54:01 PM. It ticks every second, so you’re always looking at the live SAST 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 1 hour gap is easy to see.
What's the best time for a IDT–SAST call?
For example, a 9:00 AM IDT meeting takes place at 8:00 AM SAST. 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–SAST difference?
The labels IDT and SAST 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 SAST conversion?
We don’t guess. IDT and SAST 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 SAST?
SAST is 1 hour behind IDT — a fixed 1 hour difference, since both are fixed-offset labels.
What time is it in SAST when it's 12:00 PM IDT?
When it's 12:00 PM (noon) IDT, it's 11:00 AM SAST.
Do IDT or SAST use daylight saving time?
Israel Daylight Time (IDT) observes daylight saving, alternating with IST; South Africa Standard Time (SAST) is a fixed offset with no daylight saving.
Why might the real-world IDT–SAST difference change during the year?
The labels IDT and SAST 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 SAST. Always check which label a region is currently using before you schedule.
