Wikipedia:Articles for deletion/Chinese calendar, Lunar Nodes and history
despite the opinions of some, concepts do not become both notable and suitable for inclusion on wikipedia once someone writes one or more books about them. a quick glance at  suggests that such in-depth coverage would satisfy the notability requirement, but it doesn't, because we would expect to see coverage from more than just one author on such a broad and far-reaching topic. We need |reliable third-party sources or wikipedia isn't verifiable. Not long ago, an amateur historian by the name of Gavin Menzies wrote a book claiming that Ming Dynasty explorers from china landed in America in 1421. This got a ton of third-party coverage. But since none of his claims were valid historical arguments, none of them get to be repeated uncritically here on wikipedia. The article on Zheng He, the subject of his book, doesn't even mention him or his ideas, and nor should it, but Menzies himself gets his own article because of the overwhelming media response to his work. The same principles apply here. The ideas are quakery and the author and his books aren't particularly notable, so there's no reason to include them on wikipedia
