Kiritimati (also known as Christmas Island) is a Pacific Ocean atoll in the northern Line Islands. It is part of the Republic of Kiribati. The name is derived from the English word "Christmas" written in Gilbertese according to its phonology, in which the combination ti is pronounced s, giving [kiˈrɪsmæs]. Kiritimati has the greatest land area of any atoll in the world, about ; its lagoon is roughly the same size. The atoll is about in perimeter, while the lagoon shoreline extends for over . Kiritimati comprises over 70% of the total land area of Kiribati, a country encompassing 33 Pacific atolls and islands. It lies north of the equator, south of Honolulu, and from San Francisco. Kiritimati is in the world's farthest forward time zone, UTC+14, and is therefore one of the first inhabited places on Earth to experience New Year's Day. (see also Caroline Atoll, Kiribati). Although it lies east of the 180th meridian, the Republic of Kiribati realigned the International Date Line in 1995, placing Kiritimati to the west of the dateline. Nuclear tests were conducted on and around Kiritimati by the United Kingdom in the late 1950s, and by the United States in 1962. During these tests, the island was not evacuated, exposing the i-Kiribati residents and the British, New Zealand, and Fijian servicemen to nuclear radiation. The entire island is a Wildlife Sanctuary; access to five particularly sensitive areas is restricted. Kiritimati was initially inhabited by Polynesian people. Radiometric dating from sites on the island place the period of human use between 1250 and 1450 AD. Permanent human settlement on Kiritimati likely never occurred. Stratigraphic layers excavated in fire pits show alternating bands of charcoal indicating heavy use and local soil indicating a lack of use. As such, some researchers have suggested that Kiritimati was used intermittently (likely by people from Tabuaeran to the north) as a place to gather resources such as birds and turtles in a similar fashion to the ethnographically documented use of the five central atolls of the Caroline Islands.

Line Islands

The Line Islands, Teraina Islands or Equatorial Islands (in Gilbertese, Aono Raina) are a chain of 11 atolls (with partly or fully enclosed lagoons) and coral islands (with a surrounding reef) in the central Pacific Ocean, south of the Hawaiian Islands. Eight of the atolls are parts of Kiribati. The remaining three—Jarvis Island, Kingman Reef, and Palmyra Atoll—are territories of the United States grouped with the United States Minor Outlying Islands.

Palmyra Atoll

Palmyra Atoll (pælˈmaɪrə), also referred to as Palmyra Island, is one of the Northern Line Islands (southeast of Kingman Reef and north of Kiribati). It is located almost due south of the Hawaiian Islands, roughly one-third of the way between Hawaii and American Samoa. North America is about northeast and New Zealand the same distance southwest, placing the atoll at the approximate center of the Pacific Ocean. The land area is , with about 9 miles (14 km) of sea-facing coastline and reef.
