Western Greenland Time (WGT)

WGT time now

01:32:31
Fri, 18 Jul 2025
UTC Offset: UTC -2

Western Greenland Time (WGT) operates at UTC−2 as its standard time, shifting to Western Greenland Summer Time (WGST, UTC−1) during daylight saving months. Sometimes referred to simply as "Greenland Time," WGT is used across most of western Greenland, including Nuuk and other key communities. Previously, until March 2023, WGT was set at UTC−3 with summer time at UTC−2 before advancing by one hour to its current offsets.

Importance and Global Use of WGT

WGT plays a crucial role in coordinating transportation, education, public services, and daily activities across Greenland's western regions, where long distances and harsh Arctic conditions make reliable and consistent timekeeping essential. By maintaining a clear standard time and daylight saving shift, Greenland ensures smoother scheduling for air and sea travel, health services, and community operations.

Internationally, WGT strengthens Greenland's connections with Europe and North America by narrowing time differences and supporting cooperation in trade, fisheries, Arctic research, and environmental policy. This alignment helps integrate Greenland more effectively into North Atlantic and Arctic partnerships, promoting stability and efficiency in international collaboration.

Where and When WGT is used worldwide

North America

North American countries using WGT during winter and WGST during summer:

  • Greenland - most of the country, except:
    • Thule Air Base, which uses AST/ADT time zone
    • Danmarkshavn, which observes GMT year around

Other Time Zones in UTC -2

Other time zones share the same offset as Western Greenland Time (WGT), but are known by different names. While their clocks align, they may represent different regions or countries based on local time zone definitions.
