WGST
West Greenland Summer Time
West Greenland Summer Time (WGST) covers Greenland’s most populated area around Nuuk, where daily life and business follow the Atlantic rhythm of UTC−01:00 during the bright summer months. Living and collaborating here means aligning with long daylight hours and a single, tightly observed daylight‑saving practice that shifts clocks forward in spring and back in late October.

IANA zones · the technical identifiers
The zone that resolve to WGST.
For software, always store the IANA identifier — never the abbreviation alone. The database keeps these zones distinct because their rules can, and historically did, diverge.

Frequently asked questions
Common questions about WGST, daylight saving, and how to handle it in software. Can't find what you need? Email [email protected].
- West Greenland Summer Time sounds specific—does it cover all of Greenland?
- WGST is used to describe the summer (daylight‑saving) offset on Greenland’s west coast centered on Nuuk; most inhabited parts of Greenland follow the same pattern.
- Is WGST the same year‑round?
- No. It’s a daylight‑saving period: clocks move forward in spring (currently late March) and back in late October.
- What’s the time difference from WGST to UTC right now?
- During WGST the representative zone Nuuk runs at UTC−01:00; in winter it’s typically UTC−02:00.
- Why does Greenland observe daylight saving?
- It adjusts clocks to better match daylight hours in a region with extreme seasonal changes in sunlight.
- How many member zones does WGST have?
- Just one main zone is listed, centered on Nuuk in Greenland.
- When do clocks change in WGST?
- The next change back from WGST is late October; the next spring shift to WGST is usually late March.
- Is WGST the same as Iceland or Atlantic time?
- No. WGST is specific to parts of Greenland and uses UTC−01:00 in summer, unlike other Atlantic zones.
- What country does WGST represent?
- The member country shown is Greenland.
- Is WGST currently active?
- Yes, all listed zones observing WGST are in daylight‑saving time.
