The 60 day pillars
Your day pillar is the stem-branch pair governing the day you were born — the top character is your Day Master, the part of the chart that stands for you. It rotates daily through a cycle of sixty, which is why it says far more about a person than a birth-year zodiac sign.
Each page below gives the structure, the twelve-stage position, the seated Ten God and the hidden stems — all computed by the engine — and then one honest note about what that combination tends to read like.
