The year 2012 has been at the center of many millennial theories, commonly referred to under
the umbrella term the “2012 phenomenon”. Th ese theories, which predicted important changes
for humanity usually related to some kind of environmental apocalypse, are generally described
as relating to the end of the Mayan calendar, to the common-era calendar date, 21 December
2012 (21.12.2012), and to “New Age interpretations”.
