Re the Mayan Calendar: I have to learn not to broach this topic with people as every time in comes up in conversation I end up feeling uncomfortable with where the conversations migrate to. For sure it is a controversial topic that evokes all kinds of responses from people-some positive but more often than not it causes people to be perplexed. Either from the perspective of them not knowing anything about it to trying to explain what we know of the concept only to run into challenges around the origins and the projected outcomes.
The origin of horoscopes also proved to be difficult to explain and the transition from Age of Pisces to the Age of Aquarius even more so.
Both these topics require more exploration....
