Problem: Hillary was born to Percival Augustus and Gertrude (nee Clark) Hillary in Auckland, New Zealand, on 20 July 1919. His family moved to Tuakau, south of Auckland, in 1920, after his father, who served at Gallipoli with the 15th (North Auckland) Regiment, was allocated land there. His grandparents had emigrated from Yorkshire to northern Wairoa in the mid-19th century.

Hillary married Louise Mary Rose on 3 September 1953, soon after the ascent of Everest; he admitted he was terrified of proposing to her and relied on her mother to propose on his behalf. They had three children: Peter (born 1954), Sarah (born 1955) and Belinda (1959-1975). In 1975 while en route to join Hillary in the village of Phaphlu, where he was helping to build a hospital, Louise and Belinda were killed in a plane crash near Kathmandu airport shortly after take-off. In 1989 he married June Mulgrew, the widow of his close friend Peter Mulgrew, who died on Air New Zealand Flight 901 in 1979. His son Peter Hillary also became a climber, summiting Everest in 1990. In May 2002 Peter climbed Everest as part of a 50th anniversary celebration; Jamling Tenzing Norgay (son of Tenzing who had died in 1986) was also part of the expedition. Hillary's home for most of his life was a property on Remuera Road in Auckland City, where he enjoyed reading adventure and science fiction novels in his retirement. He also built a bach at Whites Beach, one of Auckland's west coast beaches in the former Waitakere City, between Anawhata and North Piha; a friend called it Hillary's place of solace, where he could escape media attention. The Hillary family has had a connection with the west coast of Auckland since 1925, when Louise's father built a bach at Anawhata. The family donated land at Whites Beach that is now crossed by trampers on the Hillary Trail, named for Edmund. Hillary said of the area: "That is the thing that international travel brings home to me - it's always good to be going home. This is the only place I want to live in; this is the place I want to see out my days."

Question:
The 2012 phenomenon was a range of eschatological beliefs that cataclysmic or otherwise transformative events would occur on or around 21 December 2012. This date was regarded as the end-date of a 5,126-year-long cycle in the Mesoamerican Long Count calendar, and as such, festivities to commemorate the date took place on 21 December 2012 in the countries that were part of the Maya civilization (Mexico, Guatemala, Honduras, and El Salvador), with main events at Chichen Itza in Mexico, and Tikal in Guatemala. Various astronomical alignments and numerological formulae were proposed as pertaining to this date. A New Age interpretation held that the date marked the start of a period during which Earth and its inhabitants would undergo a positive physical or spiritual transformation, and that 21 December 2012 would mark the beginning of a new era.
Maya inscriptions occasionally mention predicted future events or commemorations that would occur on dates far beyond the completion of the 13th b'ak'tun. Most of these are in the form of "distance dates"; Long Count dates together with an additional number, known as a Distance Number, which when added to them makes a future date. On the west panel at the Temple of Inscriptions in Palenque, a section of text projects forward to the 80th 52-year Calendar Round from the coronation of the ruler K'inich Janaab' Pakal. Pakal's accession occurred on 9.9.2.4.8, equivalent to 27 July 615 AD in the proleptic Gregorian calendar. The inscription begins with Pakal's birthdate of 9.8.9.13.0 (24 March, 603 AD Gregorian) and then adds the Distance Number 10.11.10.5.8 to it, arriving at a date of 21 October 4772 AD, more than 4,000 years after Pakal's time. Another example is Stela 1 at Coba which marks the date of creation as 13.13.13.13.13.13.13.13.13.13.13.13.13.13.13.13.13.13.13.13.0.0.0.0, or nineteen units above the b'ak'tun. According to Linda Schele, these 13s represent "the starting point of a huge odometer of time", with each acting as a zero and resetting to 1 as the numbers increase. Thus this inscription anticipates the current universe lasting at least 2021x13x360 days, or roughly 2.687x1028 years; a time span equal to 2 quintillion times the age of the universe as determined by cosmologists. Others have suggested, however, that this date marks creation as having occurred after that time span. In 2012, researchers announced the discovery of a series of Maya astronomical tables in Xultun, Guatemala which plot the movements of the Moon and other astronomical bodies over the course of 17 b'ak'tuns.
