What Saju is, and what it is not

A calendar system, not a star system — and the difference matters more than you would think.

Saju is a Korean method of reading a life from four numbers: the year, month, day and hour you were born. Each of those four gets converted into a pair of characters from an old calendar, giving eight characters in total. Those eight characters are your chart.

The first thing to understand is what it does not use. There are no planets. There are no constellations. Nothing in Saju depends on where Mars was. It is built entirely on a calendar — a way of counting time that has been running continuously for well over two thousand years.

Why that distinction matters

Western astrology asks where the sky was. Saju asks where you sit in a cycle. The sixty-unit cycle it runs on counts years, months, days and hours simultaneously, and your chart is simply your coordinates in that cycle at the moment you arrived.

This is why Saju survives contact with sceptics better than horoscopes do. You can disagree with the interpretation. You cannot really disagree with the arithmetic — the characters are the characters, and two competent readers will always calculate the same eight.

What it claims to tell you

Two things, and the second is the interesting one.

The first is character: what you are made of, what you are naturally good at, what reliably causes you trouble. Every system claims this and you should be appropriately unimpressed.

The second is timing. Saju holds that the same chart behaves differently in different decades — that there are years when a door is open and years when it is not, and that these can be worked out in advance. This is the part with no equivalent in Western astrology, and it is the reason Saju is still routinely consulted in Korea before marriages, business launches and moves.
