Daylight saving time would cause chaos in this country, and air traffic would suffer: The phenomenon of the midnight sun versus winter darkness
In most of Europe, clocks were recently moved forward for daylight saving time, and people woke up feeling sleep-deprived, but in one European country, there are no such worries.
TL;DR
- Iceland has not observed daylight saving time since 1968.
- The country's geographic location with extreme differences in daylight hours between summer and winter makes seasonal time changes impractical.
- Adopting daylight saving time was found to cause sleep disturbances and disrupt biological rhythms.
- Time changes also complicated air traffic, which is crucial for Iceland's logistics and isolation.
- Iceland uses UTC+0, which means solar noon is naturally later than clock noon, and adding daylight saving time would further increase this discrepancy.
