History
The
Daylight saving time
Svalbard observes daylight saving time yearly by advancing the clock forward one hour from Central European Time in UTC+01:00 to Central European Summer Time in UTC+02:00. Daylight saving time begins on the last Sunday in March and ends on the last Sunday in October.[5] This is in-line with the rest of the Kingdom of Norway,[6] and has been observed in this current alignment since 1996.[7] Svalbard first observed daylight saving time by moving the clock forward one hour at inconsistent times between 1943 and 1945, and 1959 and 1965. Daylight saving time was reintroduced for a final time in 1980, and since 1996 Norway has followed the European Union regarding transition dates.[7] As Svalbard experiences midnight sun during summer, it gives daylight saving time no utility, and is only observed in order to make communicating with Norway Proper more convenient.[4]
Geography and solar time
Most of Svalbard lies within the geographical UTC+01:00 offset (also known as zone "Alpha"), including the only permanently-populated island of Spitsbergen. Places located west of 22.5° East, including the western half of Nordaustlandet, are in the geographical UTC+02:00 offset ("Bravo").[8][9][10] As Svalbard is located north of the Arctic Circle, it experiences midnight sun during summer and polar night during winter. At the 74° parallel north, the midnight sun lasts 99 days and polar night 84 days, while the respective figures at the 81° parallel north are 141 and 128 days.[11] In Longyearbyen, midnight sun lasts from 20 April until 23 August, and polar night lasts from 26 October until 15 February.[12] The difference of longitude between the western (10°29'31 E; Forlandet National Park, Prins Karls Forland)[13] and easternmost (33°30'59 E; Kræmerpynten, Kvitøya)[14] points of Svalbard results in a difference of approximately 1 hour 32 minutes of solar time.
Notation
As with the rest of Norway, the 24-hour clock is commonly used, however when speaking informally, the 12-hour clock is often used.[15]
