What we do
Saju-Link builds your birth chart from your date and time of birth and shows what those eight characters say. We read the weight of the five elements and the strength of your day master, then lay today’s pillar against the chart for a daily reading.
Reading on screen is free and needs no account. The paid items are PDF reports carrying figures the screen never shows — the ally ratio behind the strong/weak verdict, the seasonal standing of each element, and the true-solar-time correction.
What we calculate
Charts are built from the Korean lunisolar almanac, and the birth time is corrected to true solar time for the birthplace — the same clock time means a different sun position depending on where you were born.
Scores come from fixed rules only. Traditional concepts — ten gods, branch relations, the supporting element — are expressed as rules, so the same input always gives the same result. When a rule changes we run a regression harness to be sure older readings did not move.
No AI is involved in the on-screen text. Every sentence on the free screens is fixed text attached to a calculated result. Generative AI is used only in the commentary of a paid report, and even there it never produces the numbers — it writes prose from what the engine already calculated.
What we will not claim
- We do not tell fortunes. Nothing here tells you to pursue or avoid anyone. It is a reference drawn from a tradition.
- We do not store what you enter. Birth details are used for the moment of calculation and never written down; result links live in the part of the URL a browser does not send to a server.
- A score is not a verdict on a person. A low reading today is not a reason to give up on the day.
