Territories which fall within the Samoa Time Zone follow a standard time by adjusting their clocks eleven hours backwards from Coordinated Universal Time resulting in UTC – 11:00. Notably the clock time used within the Samoa Time Zone is primarily founded on the mean solar time of the 165th meridian of the London based Greenwich Observatory.
Regions which are enclosed within the American Samoa Time Zone include the Midway Atoll, the 2.4 square mile atoll in the North Pacific Ocean also known as the Midway Islands, as well as the United States unincorporated territory of American Samoa located in the South Pacific Ocean, southeast of Samoa. Also included are the unpopulated islands of Reef, Palmyra, Jarvis and Kingman.
Territories within the American Samoa Time Zone fall one hour behind the Hawaii – Aleutian Time Zone, twenty – three hours behind the Wake Island Time Zone and one hour ahead of the Howland and Baker Islands.
Prior to its move across the International Date Line on December 29, 2011 the nation of Independent Samoa was noted for its position as occurring east of the International Date Line which allowed the region to adopt an American Samoa Time of UTC – 11:00 which was adjusted to UTC – 10:00 during daylight saving time. During this period the time used by Samoa was synchronized with adjacent American Samoa, which today recognizes a year-round time of UTC – 11:00 in accordance with the Samoa Time Zone.
On Thursday December 29, 2011 Samoa had skipped the entire calendar day of Friday December 30, 2011 and moved directly into Saturday December, 31 2011 in effect repositioning the original placement of the International Date Line. Tuilaepa Sailele Malielegaoi who was the Samoan Prime Minister at the time suggested that the alteration was well-intentioned to better their business relationships with Australia, China, NewZealand and their other trade partners across Asia.
The independent territory of Samoa today recognizes a standard time of UTC + 13:00 and a time of UTC + 14:00 when observing daylight saving time in the southern hemisphere during the summer months. Daylight saving time in Samoa came to an end on Saturday April 2, 2011 at 04:00 local daylight time and began on Sunday September 25, 2011 at 00:00 local standard time. Samoa due to its location in the South Pacific Ocean by tradition did did not recognize daylight saving time and although had scheduled to introduce its use in 2009, was forced to postpone the the use of daylight saving time for another year due to the aftereffects experienced by the 2009 tsunami which impacted the islands.
Located just east of the International Date Line, Samoa along with Kingdom of Tonga, parts of the Independent and Sovereign Republic of Kiribati and the New Zealand territory of Tokelau is one of the first regions on the globe to witness the beginning of a new day.
Today the nation of Samoa is 24 hours ahead of the American Samoa standard time and and 25 hours ahead during the summer months.
