The Yin Metal Day Master · 辛 the jewel and fine blade

Refined, elegant and precise — like a polished gem or a surgeon's blade, you value quality, beauty and recognition. Sharp-minded and detail-perfect, you shine when appreciated.

At your best

Discerning, graceful, brilliant at anything requiring finesse.

What to watch

Sensitivity to slights and a critical streak; not every flaw needs naming.

Strong vs weak Yin Metal

A strong Day Master runs best with an outlet. Your energy is abundant — the work is to channel it outward into expression, ventures, leadership and giving, rather than hoarding it. Your favourable elements are the ones that let you spend energy productively.

A weak Day Master isn't a flaw — it means you run best when supported. The work is to lean on resources, mentors, allies and replenishment rather than grinding alone. Your favourable elements are the ones that feed and strengthen you.

Whether your Yin Metal runs strong or weak depends on the whole chart, not the stem alone — the calculator works it out for you.

What is a day master?

In BaZi (八字, the Four Pillars of Destiny), your day master is the Heavenly Stem of your day of birth — the single character that represents you at the centre of your chart. Everything else in BaZi is read in relation to it. There are ten day masters, one for each stem; 辛 is Yin Metal.

The other day masters

• Yang Wood (甲) — the towering tree
• Yin Wood (乙) — the vine and flower
• Yang Fire (丙) — the sun
• Yin Fire (丁) — the candle and starlight
• Yang Earth (戊) — the mountain
• Yin Earth (己) — the garden soil
• Yang Metal (庚) — the axe and raw ore
• Yang Water (壬) — the ocean and river
• Yin Water (癸) — the dew and mist
