About Africa/Khartoum

Africa/Khartoum is the IANA time zone for Sudan. It currently keeps Central Africa Time (CAT, UTC+2) all year.

Abbreviations in use: CAT. Offset page: UTC+2.

Rule for future years (POSIX TZ string)

CAT-2

The standard time is called CAT and is UTC+2. POSIX writes the offset with the opposite sign (west of Greenwich is positive), which is why the string says "-2". There is no daylight saving rule: the zone stays on this offset for every year after the end of its explicit transitions. Software that has no full tzdata copy, such as many embedded devices, can use this string directly as the TZ environment variable.

History of Africa/Khartoum since 1970

The record starts with local mean time (UTC+2:10), which ended on December 31, 1930. The first daylight saving time in the record is in 1970.

Before 1970

1 offset change before 1970 in the record:

Changes of the winter (standard) offset: Saturday, January 15, 2000, UTC+2 → UTC+3; Wednesday, November 1, 2017, UTC+3 → UTC+2.

tzdata commits to accuracy from 1970 for every zone (zone1970.tab); earlier entries are historical research and may be incomplete.

Using Africa/Khartoum 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: 'Africa/Khartoum' })

# Python 3.9+
from zoneinfo import ZoneInfo
from datetime import datetime
datetime.now(ZoneInfo('Africa/Khartoum'))

// Java
java.time.ZonedDateTime.now(java.time.ZoneId.of("Africa/Khartoum"))

// Go
loc, _ := time.LoadLocation("Africa/Khartoum")
time.Now().In(loc)

-- PostgreSQL
SELECT now() AT TIME ZONE 'Africa/Khartoum';

# Shell
TZ='Africa/Khartoum' 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.
