What forms the Sinsa day pillar?

A day pillar is the stem and branch of the birth day, rather than the birth-year animal. Sinsa is combination 18 of the sixty-pillar cycle. The engine reports a Yin Metal Day Master, Sin, above branch Sa (Fire).

The illustration uses a polished gem for Sin. Set a finish line so precision does not become a demand for perfection.

The branch Sa is Fire; its hidden stems are Mu · Gyeong · Byeong, ending with the main stem Byeong. The branch animal is Snake. This animal describes the day branch here, not automatically the person's birth-year sign.

What does White Wax Metal mean, and how does its paired pillar differ?

White Wax Metal (白蠟金) is the traditional Nayin name shared with Gyeongjin. A Nayin image is a cultural metaphor, not an element count, a useful-element prescription or proof of a personality trait. Its element can differ from the Day Master's element without being an error.

The pair makes the distinction concrete: Sinsa has main hidden stem Byeong and Direct Officer, while Gyeongjin has Mu and Indirect Resource. Their branch positions are Jisal (Earth Star) and Hwagaesal (Canopy Star). Sharing the name White Wax Metal therefore does not give the two combinations the same structure or life story.

Why is the main hidden stem classified as Direct Officer?

For Sinsa, the engine compares Day Master Sin with main hidden stem Byeong, producing Direct Officer. The surface elements are Metal and Fire; the Ten God calculation uses the hidden stem's element and polarity, not just the branch's surface label.

This element controls the Day Master with opposite polarity. Direct Officer is associated with rules and roles, without guaranteeing promotion or exam results.

This is the representative classification by the main hidden stem. Other hidden stems remain part of the chart; the month, hour and surrounding pillars can change the interpretation's emphasis.

A second comparison keeps the Day Master fixed: Sinmi also begins with Sin, but its main hidden stem is Gi, its Ten God Indirect Resource, and its Nayin Roadside Earth. In this comparison the lower character, not the upper one, changes the result. Compare the actual fields before borrowing an interpretation from another pillar with the same stem.

When do the next Sinsa days occur?

Starting from 26 October 2026, these are the next three calendar days whose engine dayGZ() equals Sinsa. They repeat at 60-day intervals. A matching day is not a promise of a successful exam, contract or relationship, and does not require moving a real appointment.

Calendar date (as of 2026-10-26)Day pillar
2026-11-03 · TueSinsa (辛巳)
2027-01-02 · SatSinsa (辛巳)
2027-03-03 · WedSinsa (辛巳)

A recurring day is a shared calendar label, not a private appointment with fortune. You can put it beside a journal entry and compare what actually happened, including observations that do not fit the interpretation. After the three dates listed here pass, check the calculator again for the next cycle; the article's reference date does not move automatically.

What does the Void pair Sin·Yu mean?

The engine's sixty-cycle table gives Sin·Yu for Sinsa. Gongmang, often called Void, identifies two unused branches in its ten-day group. A two-pillar Nayin pair and a ten-day group are different classifications.

Seeing either branch elsewhere in a chart does not erase a person, relationship or opportunity. Treat this as an auxiliary traditional idea, not a reason to cancel plans or spend money. Real circumstances take priority.

Why is this branch in the Jisal (Earth Star) position?

Here the reference is the day branch Sa's own Three Harmony group, and the target is Sa again. That produces Jisal (Earth Star). It is not a calculation from the birth-year branch and does not list every star in a full chart.

A beginning branch is linked with movement and starting. It does not foretell travel or relocation; check practical time and resources before changing plans.

Can Sinsa alone determine personality, compatibility or work?

Sinsa is one pillar of a complete saju chart. A different birth month, hour, other pillars and long-term periods can change the context. These two characters cannot fix personality, marriage prospects or career, and MBTI uses a different basis rather than an interchangeable code.

Use interpretations as questions to compare with experience. They do not guarantee outcomes or support medical, legal or investment decisions. The linked concept guides explain the terms before any personal interpretation.

First confirm that a birth date is Gregorian or convert a known lunar date using the correct country's calendar. For a day pillar, year alone is insufficient. Time near the late-night day boundary also requires a stated convention. The web calculator offers optional corrections; use the same options when comparing two results rather than assuming different displays prove an error.

Frequently asked questions

What is the Sinsa day pillar?

It is 辛巳, combination 18 of sixty. Its Nayin is White Wax Metal; its Void branches are Sin·Yu.

What is Sinsa's day-branch Ten God?

Using main hidden stem Byeong within Mu · Gyeong · Byeong, the engine computes Direct Officer relative to Sin. This is the main-stem classification.

When is the next Sinsa day?

As of 2026-10-26: 2026-11-03, 2027-01-02, 2027-03-03. These calendar days recur every 60 days and do not guarantee a good outcome.

Is Jisal (Earth Star) the only star in a Sinsa chart?

No. Jisal (Earth Star) here describes the day branch's position within its own Three Harmony group. A full chart and another reference branch can give other classifications.
