IDT
Israel Daylight Time
Israel Daylight Time (IDT) is used across Israel, advancing one hour ahead during summer months so evenings stretch later under Mediterranean skies—making it a one‑zone, always‑forward clock for Jerusalem and the country’s full territory, with all member zones observing daylight saving and currently sitting at UTC+03:00.

About IDT
Standard time, with a summer shift.
Israel Daylight Time (IDT) is used across Israel, advancing one hour ahead during summer months so evenings stretch later under Mediterranean skies—making it a one‑zone, always‑forward clock for Jerusalem and the country’s full territory, with all member zones observing daylight saving and currently sitting at UTC+03:00.
IANA zones · the technical identifiers
The zone that resolve to IDT.
For software, always store the IANA identifier — never the abbreviation alone. The database keeps these zones distinct because their rules can, and historically did, diverge.

Frequently asked questions
Common questions about IDT, daylight saving, and how to handle it in software. Can't find what you need? Email [email protected].
- What does IDT abbreviation stand for?
- IDT stands for Israel Daylight Time, the daylight saving designation used when clocks move forward from the standard Israel Standard Time to extend evening daylight across Israel.
- Which city represents this region?
- Jerusalem is the representative zone for IDT, reflecting the country‑wide practice of advancing clocks during daylight saving and anchoring the region’s timing to this central reference.
- Is the whole region always on daylight saving?
- All member zones in this region observe daylight saving, so the country shifts clocks forward together rather than split‑timing, giving you one consistent offset at any given moment.
- When does the current offset apply?
- Since late March the region has been operating under the daylight hours setting, meaning later sunsets and longer evenings through the summer months.
- When is the next clock change?
- The next transition is scheduled for late October at 1:00 AM local time, when clocks step back to the standard offset and daylight hours end for the year.
- How does this affect cross‑time collaboration?
- With the entire country advancing together, you only need one reference offset for Jerusalem, simplifying scheduling across Israel during summer windows.
- Is Jerusalem always UTC+03:00?
- A single forward shift applies in summer, so the current offset is one hour ahead of standard, giving longer evenings across Israel.
- Does IDT cover multiple countries?
- No, IDT is used exclusively by Israel, giving the region a single, unified clock rather than multiple countries under one code.
- What makes IDT unique?
- Unlike multi‑zone regions, IDT always behaves as a single clock across one country, advancing and retreating in sync under Mediterranean skies.
