Geography and solar time
Most of Iceland lies within the geographical UTC−01:00 offset, including the capital Reykjavík, while the westernmost points of Iceland located west of 22.5° West, including Ísafjörður and the Keflavík International Airport, lie within the geographical UTC−02:00 offset.[15][16][17] Despite this, Iceland observes UTC±00:00 in order to be in sync with Europe, which results in noon being an hour behind other countries in the same offset, for example 88 minutes behind London.[15] Midnight sun in Iceland can be experienced in summer on the island of Grímsey off the north coast;[18] the remainder of the country, since it lies just south of the polar circle, experiences a twilight period during which the sun sets briefly, but still has around two weeks of continuous daylight during the summer.[19][20] The difference of longitude between the western (Bjargtangar; 24°32"W)[21] and easternmost (Hvalbakur; 13°16"W)[22] points of Iceland results in a difference of approximately 45 minutes of solar time.
Effects on health
As Iceland observes UTC±00:00 instead of the geographical UTC−01:00 or UTC−02:00, this results in noon being 88 minutes behind other countries in the same offset.
