I'll share something interesting...

I was listening to an old Terence McKenna lecture on the Hermetic Doctrines and he was just releasing his TimeWave Zero theory. H referred to his end date as "December 22, 2012" repeatedly in the lecture.

I've always suspected the date is ambiguous at best and was "tweaked" to fit a specific date by TPTB to give everyone a false sense of Pessimism/Optimism (like Y2K) while keeping the real date of transition a secret.
