Your day master is Sin, the eighth heavenly stem. Where Gyeong is raw ore, Sin is metal that has already been worked: a gem, a needle, a scalpel, a piece of jewelry. It is small, refined and valuable. In your chart this character stands for you.
People with a Sin day master are often described as elegant, exacting and sensitive. You tend to have high standards for yourself and others, you notice quality, and you can be hurt more easily than your composure suggests. You may care how things are done as much as whether they get done.
A jewel wants to be washed and shown, not melted. In the balance below, water cleans and shows off your shine, earth holds you, and heavy fire can feel like being put back in the forge. Balance here reads as polish.
The image
Sin is yin metal: jewels, fine blades, coins, the ring on a hand. The Hanja 辛 also means spicy or bitter, and the tradition links Sin with sharpness of taste and word. It is metal already transformed, so it is read as refined and a little proud of it.

At work
Sin often does well where precision and presentation matter: design, finance in the craft sense, medicine as a technical skill, editing, analysis, luxury trades. You may be the quality check everyone trusts. The friction comes with messy, careless environments.
With other people
With people, Sin tends to be charming and a little guarded. You may choose friends carefully and keep them long. The tradition's image of a jewel being washed clean suggests you do best with people who let you be seen.
Birth season
Autumn and the earth months support Sin. Winter water is read as washing the jewel clean, often a favorable picture in traditional readings. Summer fire is read as the testing season for fine metal. Spring gives Sin a lot of wood to deal with, which is read as busy.
Stem combination
Sin combines with Byeong 丙, yang fire: sunlight on a jewel. The pair turns toward water and is traditionally called the combination of dignity. It is read as a pull between polish and warmth.

Your day master sits on one of six branches. Each pairing is its own day pillar.
