Black Monkey · A great spring welling up through rock
Yang Water — the open sea. You are seated on the metal energy that feeds you — there is something to lean on underfoot.
Newly born energy. It learns fast and grows easily, and it tends to receive care from the people around it without having to ask.
An unorthodox teacher sits in the inner room. Intuition and an original mind sit here — along with a head too busy for deep sleep.
The stems concealed inside 申 (Monkey). A branch is not one single energy — it holds this mixture, in these proportions across a 30-day month.
A spring welling endlessly through rock — the mind turns quickly and the ideas do not run out. There are many channels, so many things get started; the force multiplies when the streams are gathered into one.
Is Ren Shen 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 Shen (壬申) 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 Monkey — the image traditionally attached to it is "A great spring welling up through rock". Your Day Master 壬 (Yang Water — the open sea) sits on 申, the Monkey, which carries Metal. In the twelve-stage cycle that position reads as Birth, and the seated Ten God is Indirect Resource.
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. 壬申 is romanised Ren Shen from Mandarin and imsin 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.
