East Greenland Summer Time
East Greenland Summer Time (EGST) follows the rhythms of the far northeast coast of Greenland, where communities like Scoresbysund live on UTC−1 during the brighter months—well ahead of the more familiar Western European time—and shift two hours ahead of the base UTC−2 zone in summer to keep pace with the midnight sun.

About EGST
Standard time, with a summer shift.
East Greenland Summer Time (EGST) follows the rhythms of the far northeast coast of Greenland, where communities like Scoresbysund live on UTC−1 during the brighter months—well ahead of the more familiar Western European time—and shift two hours ahead of the base UTC−2 zone in summer to keep pace with the midnight sun.
IANA zones · the technical identifiers
The zone that resolve to EGST.
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.

These named zones share EGST's offset today. When daylight saving rules differ, they drift apart for part of the year.
Frequently asked questions
Common questions about EGST, daylight saving, and how to handle it in software. Can't find what you need? Email [email protected].
- Why does East Greenland use a one-hour summer offset?
- During the long Arctic summer, clocks shift from the base UTC−2 zone (America/Scoresbysund) to UTC−1, making evening daylight more useable and keeping schedules roughly aligned with Denmark and eastern Europe.
- Is East Greenland Summer Time unique in Greenland?
- Yes—Greenland spans three other offsets (including UTC−3 and UTC−4), but Scoresbysund is alone in this UTC−2 / UTC−1 pattern, closely tied to Denmark and Iceland rather than to Arctic Canada.
- What happens at the end of EGST each year?
- Around late October, clocks go back by one hour, returning to the standard UTC−2 (East Greenland Time) until the next March, when summer time begins again.
- How does daylight saving affect daily life in Scoresbysund?
- Shifting to UTC−1 in spring stretches useful light into the evening, which simplifies travel and communication across fewer time differences with Europe and the wider North Atlantic.
