Black Tiger · A tiger swimming a great river
Yang Water — the open sea. You are seated on the energy you produce, so your force flows outward rather than pooling.
Energy folding inward. Sensitivity and empathy deepen here — the mind runs busier than the body.
The rice bowl is seated in your inner room. Appetite, ease of expression and an unhurried optimism are laid under this seat.
The stems concealed inside 寅 (Tiger). A branch is not one single energy — it holds this mixture, in these proportions across a 30-day month.
A tiger swimming a great river — nerve and intelligence moving together, over a wide range. The scale of what gets started makes for an interesting life, and the shallows underfoot, meaning practical management, still need minding.
Is Ren Yin actually your day pillar?
The day pillar shifts on solar-term and zi-hour boundaries, so it is not countable by eye. Enter your birth date and the engine computes it in under a minute — free, no account.
Find my day pillar — freeYour day pillar is the stem-branch pair governing the day you were born — Ren Yin (壬寅) in this case. It rotates every day through a cycle of sixty, and the boundaries depend on solar terms and the 11pm zi-hour rule, so it is not something you can count by eye. Enter your birth date in our free reading and the engine computes it directly.
Black Tiger — the image traditionally attached to it is "A tiger swimming a great river". Your Day Master 壬 (Yang Water — the open sea) sits on 寅, the Tiger, which carries Wood. In the twelve-stage cycle that position reads as Ailing, and the seated Ten God is Output.
No. The day pillar is two characters out of eight — your core axis, not the whole picture. The year, month and hour pillars, the balance of the five elements, and your decade luck all have to be laid on top before a reading means much. Treat a day-pillar page as the doorway, not the room.
Same sixty-cycle, different reading of the same characters. 壬寅 is romanised Ren Yin from Mandarin and imin from Korean, and Korean saju calls the day pillar ilju (일주). The calculation is identical; the interpretive traditions differ.
The twelve-stage position, seated Ten God and hidden stems are computed by the Ioreum deterministic engine (ruleset ioreum-2026.07). The reading itself is interpretation from the day-pillar tradition, not verified science — we always tell you which part is calculation and which part is tradition.
