About Sky & Season

Where this comes from

Long before weather apps, careful observers tracked the turning of light and the rhythm of the seasons, and wrote down how those cycles tend to meet a person born into them. That record is not a verdict on a life. It is a map of the weather that moves through one. We read it in plain English.

How it started

Sky & Season grew out of one person’s study notes. Its founder, based in Singapore, spent years working through the classical texts on BaZi, Zi Wei Dou Shu and Qi Men Dun Jia — and kept wishing they came with a plain-English layer: not a watered-down version, but the same chart explained the way a good teacher would explain it over coffee.

So the site has two readings of every chart. The Inner Constellation tells your chart as a story, with no terms to learn. Classic shows the traditional chart underneath, with every term explained the first time it appears. Both come from the same calculation, and you can switch between them at any point.

Our approach

Every chart on this site comes from classical calculations — the BaZi four pillars divided at the solar terms, the Zi Wei Dou Shu twelve palaces from the lunar calendar, and a Qi Men board cast for the moment a question is asked. Then we do the translating. Each classical term is explained in one plain line the first time it appears, and the reading talks about tendencies and good windows, never guarantees.

• Classical calculations, checked against published almanacs.
• Correct historical time zones for your birth place and date.
• Every page says what is calculated and what is interpretation.
• Your birth data stays in your browser unless you choose to save it.

Where the knowledge comes from

We are students of this tradition, not a lineage school, and we say so. The calculations follow the classical conventions set out on the methodology page and are cross-checked against published almanacs and open-source engines; the interpretations draw on the classical texts and on modern teachers, and are written to describe tendencies and timing, never to promise outcomes.

If you find a chart you believe is wrong, tell us. Every report is checked, and the methodology page lists the simplifications we know about.
