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 IST, daylight saving, and how to handle it in software. Can't find what you need? Email [email protected].
- When does Israel switch back to Standard Time?
- Israel moves from daylight saving (IDT) back to standard time (IST) on the last Sunday in October, when clocks are set back by one hour at 2:00 a.m.
- How many time codes does Israel Standard Time include?
- The region has just one zone (Jerusalem), so IST neatly represents the official time for all of Israel without internal variations.
- Does Israel use daylight saving time?
- Yes, Israel observes daylight saving: from the Friday before the last Sunday in March to the last Sunday in October it runs on UTC+03:00 (IDT) instead of its standard UTC+02:00 (IST).
- Why is DST in Israel different from Europe or the US?
- Since 2013, Israel has started daylight saving time on the Friday before the last Sunday in March, two days before Europe, and ended it on the last Sunday in October, the same day as Europe. The US changes on different dates. Before 2013 the end date was tied to the Jewish holidays around Yom Kippur, so it moved from year to year.
- How does IST affect coordination with Europe?
- Israel moves its clocks forward two days before the EU in March and back on the same day in October, so it stays one hour ahead of Central Europe all year except for those two days in March, when the gap is two hours.
- How far ahead is Israel compared to London?
- Israel is two hours ahead of London almost all year: UTC+02:00 vs UTC+00:00 in winter, and UTC+03:00 vs UTC+01:00 in summer. For two days in late March, between Israel's Friday clock change and the UK's Sunday change, the gap is three hours.
- Why does IST jump from UTC+02 to UTC+03?
- UTC+02:00 is Israel Standard Time (IST) used in winter, while UTC+03:00 is Israel Daylight Time (IDT) applied in summer to extend evening daylight.
- Is Jerusalem always in sync with Israel Standard Time?
- Yes, Jerusalem follows the national rulebook, so it always keeps official Israeli time (IST in winter, IDT in summer), matching every other location across the country.
