Soft climbing wood finding grip in winter-hard earth.

In BaZi, the day pillar is the pillar of the self. Its heavenly stem is your Day Master — the reference point for every other character in the chart. A person born on a Yi Chou day has Yi wood as their Day Master, sitting on the 丑 (earth) branch.

Personality

Yi wood bends rather than breaks, and the Ox gives it endurance. You are diplomatic, quietly stubborn, and far more resilient than you look. You rarely announce your boundaries — you simply outlast pressure.

Work and vocation

Skilled at adapting a method until it fits. Design, operations, counselling, editing, or any craft where patience compounds.

Relationships

Loyal and steady, but slow to voice resentment. Say the uncomfortable thing earlier than feels natural.

Health and rhythm

Digestive sensitivity and tension held in the shoulders. Regular meals matter more than strict diets.

Upcoming 乙丑 days

The sexagenary day cycle repeats every sixty days. These are the next dates that fall on Yi Chou.
