John Major Jenkins (4 March 1964 – 2 July 2017)[1] was an American author and pseudoscientific researcher.
He is best known for his works that theorize certain astronomical and esoteric connections of the calendar systems used by the Maya civilization of pre-Columbian Mesoamerica.
His writings are particularly associated with 2012 millenarianism and the development of Mayanism in contemporary and popular culture, as an outgrowth from the New Age milieu.
[2] He is one of the principal figures who have promoted the idea that the ancient Maya calendar ends on 21 December 2012 and that this portended major changes for the Earth[vague].
[8]: 322 Jenkins is also a supporter of “The Lost Star” theory[9] which extrapolates the existence of a binary companion of the Earth’s sun based on a believed mathematical discrepancies in “earth wobble.”[10] In October of the year 2000, Jenkins work was featured on two episodes of Places of Mystery series on the Discovery Channel.
