About Asia/Jerusalem

Asia/Jerusalem is the IANA time zone for Israel. It currently keeps Israel Standard Time (IST, UTC+2) in winter and Israel Daylight Time (IDT, UTC+3) in summer.

Its principal location is Jerusalem at 31.78° N, 35.22° E.

Abbreviations in use: IST, IDT. Offset page: UTC+2.

Rule for future years (POSIX TZ string)

IST-2IDT,M3.4.4/26,M10.5.0

The standard time is called IST and is UTC+2. POSIX writes the offset with the opposite sign (west of Greenwich is positive), which is why the string says "-2". Daylight saving time is called IDT and is UTC+3. It starts on the fourth Thursday of March at 26:00 and ends on the last Sunday of October at 02:00, local time. Software that has no full tzdata copy, such as many embedded devices, can use this string directly as the TZ environment variable.

Using Asia/Jerusalem in code

Every major platform reads the same IANA ID. Store instants in UTC and convert with the ID at display time; never store a fixed offset for a place that has daylight saving time.

// JavaScript
new Date().toLocaleString('en-US', { timeZone: 'Asia/Jerusalem' })

# Python 3.9+
from zoneinfo import ZoneInfo
from datetime import datetime
datetime.now(ZoneInfo('Asia/Jerusalem'))

// Java
java.time.ZonedDateTime.now(java.time.ZoneId.of("Asia/Jerusalem"))

// Go
loc, _ := time.LoadLocation("Asia/Jerusalem")
time.Now().In(loc)

-- PostgreSQL
SELECT now() AT TIME ZONE 'Asia/Jerusalem';

# Shell
TZ='Asia/Jerusalem' date

Platforms ship their own copy of tzdata and update it on their own schedule. After a rule change, outputs can differ until the platform updates; this page uses tzdata 2026f.
