About Pacific/Norfolk

Pacific/Norfolk is the IANA time zone for Norfolk Island. It currently keeps UTC+11 in winter and UTC+12 in summer.

Its principal location is Norfolk at 29.05° S, 167.97° E.

Rule for future years (POSIX TZ string)

<+11>-11<+12>,M10.1.0,M4.1.0/3

The standard time is called “+11” (a numeric abbreviation) and is UTC+11. POSIX writes the offset with the opposite sign (west of Greenwich is positive), which is why the string says "-11". Daylight saving time is called “+12” (a numeric abbreviation) and is UTC+12. It starts on the first Sunday of October at 02:00 and ends on the first Sunday of April at 03:00, local time. Software that has no full tzdata copy, such as many embedded devices, can use this string directly as the TZ environment variable.

Upcoming transitions

Computed from tzdata 2026f; local times are read on the clock just before each change.

Using Pacific/Norfolk 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: 'Pacific/Norfolk' })

# Python 3.9+
from zoneinfo import ZoneInfo
from datetime import datetime
datetime.now(ZoneInfo('Pacific/Norfolk'))

// Java
java.time.ZonedDateTime.now(java.time.ZoneId.of("Pacific/Norfolk"))

// Go
loc, _ := time.LoadLocation("Pacific/Norfolk")
time.Now().In(loc)

-- PostgreSQL
SELECT now() AT TIME ZONE 'Pacific/Norfolk';

# Shell
TZ='Pacific/Norfolk' 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.
