How 星と暦 is made

Comparing classical texts and finding approachable words

Where do the words in a reading come from, and how are they interpreted? This list introduces 39 Eastern and Western books and research sources, together with the libraries used for calculations. The chapters, sections and calculation methods consulted are stated in turn, and their ideas are rewritten in everyday language.

How it is made

  1. Checking the sources: distinguish original works from modern translations and annotations, recording the passages checked and conditions of use.
  2. Calculating the placements: calculate calendars and planetary positions with libraries, checking boundary instants and how missing inputs are handled.
  3. Separating interpretation from wording: retain observed placements as evidence and adapt their meaning to everyday situations.
  4. Reviewing and refining: check agreement between everyday and specialist conclusions, repeated wording and expressions that might stir fear.

We believe a reading's enjoyment matters alongside its accuracy. Our aim is something you can approach easily and leave feeling a little more ready to move forward.
