Atlantic/Jan_Mayen: The Remote Arctic Time Zone
Atlantic/Jan_Mayen is the IANA time zone identifier for the remote Norwegian island of Jan Mayen, located in the North Atlantic Ocean. It observes Central European Time (CET) as standard time and Central European Summer Time (CEST) during daylight saving. This zone is used solely by Jan Mayen, a volcanic island with a small rotating population of military and meteorological personnel.
Where Atlantic/Jan_Mayen Applies
The zone applies exclusively to Jan Mayen, a Norwegian territory at 71°N latitude. The island has no permanent residents; its population consists of staff at the Jan Mayen weather station and a Norwegian Armed Forces detachment. The zone is identical to Central European Time, matching the time used in most of continental Europe.
Offset and Abbreviation
Standard time is UTC+01:00, abbreviated as CET (Central European Time). During daylight saving, clocks shift to UTC+02:00, abbreviated as CEST (Central European Summer Time). The abbreviations are used internationally for this zone.
Daylight Saving Time Behavior
Jan Mayen observes DST in line with European Union rules. Clocks spring forward on the last Sunday of March at 01:00 UTC (02:00 CET) and fall back on the last Sunday of October at 01:00 UTC (03:00 CEST). Recent and upcoming transitions:
- 2025: forward March 30, back October 26
- 2026: forward March 29, back October 25
This pattern repeats annually, providing longer daylight in the high-latitude summer.
Countries and Cities
The only location in this zone is Jan Mayen itself. The main settlement is Olonkinbyen, home to the weather station and military base. The island is uninhabited outside of these facilities.
