About America/Iqaluit

America/Iqaluit is the IANA time zone for Eastern: NU (most areas) in Canada. It currently keeps Eastern Standard Time (EST, UTC−5) in winter and Eastern Daylight Time (EDT, UTC−4) in summer.

Its principal location is Iqaluit at 63.73° N, 68.47° W.

Abbreviations in use: EST, EDT. Offset page: UTC−5.

Rule for future years (POSIX TZ string)

EST5EDT,M3.2.0,M11.1.0

The standard time is called EST and is UTC−5. POSIX writes the offset with the opposite sign (west of Greenwich is positive), which is why the string says "5". Daylight saving time is called EDT and is UTC−4. It starts on the second Sunday of March at 02:00 and ends on the first Sunday of November 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.

Upcoming transitions

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

Using America/Iqaluit 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: 'America/Iqaluit' })

# Python 3.9+
from zoneinfo import ZoneInfo
from datetime import datetime
datetime.now(ZoneInfo('America/Iqaluit'))

// Java
java.time.ZonedDateTime.now(java.time.ZoneId.of("America/Iqaluit"))

// Go
loc, _ := time.LoadLocation("America/Iqaluit")
time.Now().In(loc)

-- PostgreSQL
SELECT now() AT TIME ZONE 'America/Iqaluit';

# Shell
TZ='America/Iqaluit' 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.
