The free chart

What you get before you pay anything

The chart itself is free and stays free. Paid reports go deeper — but the core reading is not held back behind a paywall.

01

Your Four Pillars

Year, month, day, and hour — the four pairs of heavenly stems and earthly branches that make up a saju chart.

02

Your Day Master

The day stem is the traditional center of the reading. We name your archetype and explain what it describes.

03

Five Elements balance

Wood, fire, earth, metal, and water — how much of each is present, and what an imbalance traditionally suggests.

04

2027 preview

The year stem and branch for 2027 and what the classical reading says about the year’s overall tone.

Method

A chart is arithmetic, not a mood

Saju is a calendar system before it is an interpretive one. Your birth moment fixes a position in the 60-year stem–branch cycle; from there the year, month, day, and hour pillars follow from classical rules, including solar-term boundaries and the timezone you were born in.

We compute that part deterministically and show the result. The interpretation that follows is written in plain language and grounded in the same tradition — not generated fresh each time you refresh the page.

What this is not

  • Not a prediction of specific events, and not evidence about your future.
  • Not medical, psychological, or financial advice.
  • Not a substitute for a professional who knows your actual circumstances.
  • No birth time? The day pillar still computes; the hour pillar is skipped and labelled as such.
Input
Date, time, timezone. The moment is converted to the local solar calendar before any pillar is assigned.
Rules
Classical Four Pillars. Stem–branch cycle, solar-term month boundaries, ten gods, and element counts with seasonal weighting.
Output
One chart, one reading. Four pillars, day master, element balance, and the year preview — identical on every run.
Checks
Hand-audited samples. Report outputs are compared against manual calculation before release.
Limits
Stated, not buried. Where the tradition is ambiguous, the report says so instead of inventing certainty.

FAQ

Questions, answered plainly

No mysticism and no small print gymnastics. Here is exactly what this is, and what it isn’t.

Is this fortune-telling?
No. Saju maps tendencies in a traditional Korean framework — where effort tends to flow and where it meets friction. We publish it as a reflection tool, not a prediction service, and we state that limit on every report.
How is this different from a Western horoscope app?
Western apps read a sun sign and usually serve templated daily text. We compute all four pillars from your exact birth moment using classical rules, and the same input always produces the same chart. The method is documented instead of hidden.
Do I need my exact birth time?
It adds depth — the Hour pillar is one quarter of the chart. Without it, your Day pillar (the core archetype) and the rest of the chart still compute; only the Hour pillar is skipped.
What is free and what is paid?
The chart itself is free: Four Pillars, Day Master archetype, Five Elements balance, and a 2027 preview. Paid PDF reports are one-time purchases — the 2027 Year Ahead ($9.99), the Couple’s Compatibility Report ($14.99), and the 10-Year Life Chapters ($12.99). No subscription.
Is my birth data stored or sold?
Birth data is used to calculate your chart. We do not sell personal data. Our Privacy Policy explains what is stored, for how long, and how to request deletion.
Can I get a refund?
Yes. Digital reports are refundable under the terms in our Refund Policy if the file was not as described. That page also includes a request form.
