性格Ji Si personality

纳音Nayin: Wood of the Great Forest
Each pair of pillars shares one of 30 Nayin, or "sound" elements. Ji Si belongs to Wood of the Great Forest, pictured as a great forest: strength in numbers, slow and broad growth. Nayin is an older layer of Chinese astrology and is read as a background image, not as your Day Master's element.

In BaZi the day branch is the spouse palace. For Ji Si it holds the Snake, which traditionally harmonises with the Monkey (six harmony) and the Rooster and Ox (three harmony), and clashes with the Pig.
The most harmonious day pillar for Ji Si is Jia Shen (甲申): its stem combines with yours and its branch forms a six-harmony pair (天合地合). The most challenging are Yi Hai (乙亥) and Gui Hai (癸亥): stem against stem and branch against branch (天克地冲). Other pillars in your chart matter more than this single pairing.
空亡Void branches
Ji Si belongs to the Jia Zi (甲子) decade (旬), whose void branches are Xu and Hai (戌亥: Dog, Pig). Traditionally, years and months of these branches are said to make plans feel less solid. The next such years: 2030, 2031, 2042, 2043.
日期When does Ji Si come round?
As a day: the 60-day cycle repeats every 60 days. Next Ji Si days: Oct 22, 2026 · Dec 21, 2026 · Feb 19, 2027 · Apr 20, 2027. As a year pillar: 1929, 1989, 2049.
