EGST
East Greenland Summer Time
East Greenland Summer Time (EGST) is the summer clock of Scoresbysund (Ittoqqortoormiit) on Greenland’s remote east coast. From late March to late October, clocks there move one hour ahead, from UTC−2 to UTC−1, at the same moment as Europe’s clock changes and on the same schedule as Nuuk.

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.

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 UTC−2 to UTC−1, at the same moment as Denmark and the rest of Europe change their clocks.
- Is East Greenland Summer Time unique in Greenland?
- No. Since March 2024, Nuuk and most of western Greenland follow the same UTC−2 / UTC−1 pattern as Scoresbysund. Greenland’s other clocks are Danmarkshavn, on UTC+0 all year, and Pituffik (Thule Air Base), which switches between UTC−4 and UTC−3 on North American dates.
- 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 moves an hour of daylight into the evening. Because Europe changes its clocks on the same dates, the time difference with Copenhagen stays at three hours all year.
