Passage: Many assertions about the year 2012 form part of Mayanism, a non-codified collection of New Age beliefs about ancient Maya wisdom and spirituality. The term is distinct from "Mayanist," used to refer to an academic scholar of the Maya. Archaeoastronomer Anthony Aveni says that while the idea of "balancing the cosmos" was prominent in ancient Maya literature, the 2012 phenomenon did not draw from those traditions. Instead, it was bound up with American concepts such as the New Age movement, 2012 millenarianism, and the belief in secret knowledge from distant times and places. Themes found in 2012 literature included "suspicion towards mainstream Western culture", the idea of spiritual evolution, and the possibility of leading the world into the New Age by individual example or by a group's joined consciousness. The general intent of this literature was not to warn of impending doom but "to foster counter-cultural sympathies and eventually socio-political and 'spiritual' activism". Aveni, who has studied New Age and search for extraterrestrial intelligence (SETI) communities, describes 2012 narratives as the product of a "disconnected" society: "Unable to find spiritual answers to life's big questions within ourselves, we turn outward to imagined entities that lie far off in space or time—entities that just might be in possession of superior knowledge."

Question: When did the phenomenon occur?
