about once a decade there is some societal scare like this that encourages people to live life before they die (or act like complete ass hats because they think they're going to die [or kill themselves so they can die first]).
the most recent: Y2K. why would computers listing the date as 1900 make the world end? no one knows.
in the same vein, why would a calendar ending make the world end? your calendar ends every year. plenty of lunar, fortnight, and obscure time measurements occur across various historical communities. for some reason people have latched on to Mayan calendars (images frequently misused to present Aztec calendars) as the new coming of the apocalypse.
it is wrong.
they are wrong.
I am looking forward to the suicide rates.
