What does the Xin Si Day Pillar mean?

The Day Pillar is the two characters of the day you were born: a Heavenly Stem on top (your Day Master, the “you” of a Saju chart) and an Earthly Branch below (your inner self and spouse palace). In Xin Si (辛巳), the Day Master is Xin Metal (a finely cut jewel) sitting on the Snake branch, whose element is Fire.

You sit on the fire that governs you (Direct Officer), a Day Pillar that shines by tempering. Strict in self-management and honor-minded, bright and with a good competitive sense.

Xin Si personality: the Xin Metal Day Master

Xin Metal is delicate and values polish, like a well-cut jewel. You have a strong aesthetic sense and a sharp eye that misses no detail. Proud and disciplined, you often give an impression of refinement. You can be sensitive and vulnerable to stress, so it helps to find your own ways to calm your mind.

What makes Xin Si different from the other five Xin Metal Day Pillars is the branch it sits on, covered below.

The Snake seat: your inner self

With Si beneath your Day Master, you are quick-witted with a good competitive sense and hide passion inside. There is the energy of bright Fire in your spouse seat, so you connect with smart, attractive people. When jealousy and attachment rise, the ease of pausing for one beat protects the relationship.

Xin Si in love and marriage

The energy of proper responsibility (Direct Officer) sits in your spouse seat, so you tend to meet courteous, trustworthy partners. It is a foundation for a stable marriage.

Xin Metal loves in a refined, delicate way. You remember your partner’s tastes and details and show sensory consideration, but pride means it takes time to approach first or apologize. Put the relationship before pride.

Direct Officer here means: Direct Officer (Zheng Guan) stands for honor, responsibility and the power to keep order. You value principle and perform your role faithfully, so you often earn trust and recognition from others. Your luck in organizations and social position tends to be stable, and a steady, upright attitude leads over time to big results.

Energy and life stage

Death (Si): the energy of folding up activity and sorting things out. Quiet outside, but deep in inner life and reflection.

Hidden inside the Snake branch: Wu (Earth, 7 days), Geng (Metal, 7 days), Bing (Fire, 16 days). These quieter energies show up in private, under stress or later in life.

Health tendencies of Metal Day Masters

Areas to look after: lungs, large intestine, bronchi, skin and nose.

Too much Metal energy dries the airways and skin, and feelings can turn dry and edgy. Fluids, humidity, soft food and warm conversation restore balance.

Too little Metal energy leaves bronchi and skin weak and prone to colds in changing seasons. Look after breathing exercises, clean air and regular bowel habits.

Xin Si compatibility

  • Six Harmony: the Snake pairs with the Monkey. People with a Monkey Day Branch often feel an easy pull toward you.
  • Three Harmony: the Ox · Rooster · Snake form a Metal team, so those animals tend to bring out your best.
  • Clash: the Snake clashes with the Pig. It is not doom, only a spot where friction and change come easily.
  • Perfect match on stem and branch: Bing Shen (丙申) combines with Xin Si on both the stem and the branch.
  • Opposite pillar (most friction): Ding Hai (丁亥): its stem is Seven Killings to you and its branch clashes with yours.

Day Pillars are one part of compatibility. For a full comparison of two charts, try the compatibility reading.
