I would like to ask why a person born 23.1.1947 is Ren Yin from month and Ding Hai from year according to Geomancy - and Xin Chou in the year of Bing Xu according to other calculators like FOUR Pillars? I read that in some years one month is added, probably it will happen in 2033, yet has a month been added also in 1947? How often is an extra month added? In both cases i referred to solar calendar, as this difference turned out during my parents' relationship analysis, where lunar months were also quoted. Thank you for help. Victoria Herocten
