Time in Iceland

Iceland observes UTC+00:00 year-round — also known as Greenwich Mean Time. UTC+00:00 was adopted on 7 April 1968 for Iceland to be in sync with Western European Time, replacing UTC−01:00. Iceland no longer observes daylight saving time — since 1994, there have been an increasing number of proposals made to the Althing to reintroduce daylight saving time, all of which were rejected.

Geographically, most of Iceland lies within the UTC−01:00 offset. However, Iceland observes UTC+00:00 in order to be in sync with Europe, which results in solar noon being significantly later than other countries in the same offset. Health experts have argued that this gives Icelanders social jet lag as the daylight is a misalignment of biological and social time, resulting in detrimental health effects. Despite this, the government decided in 2020 not to change time zones.
