Question 1

What does the 0–100 solunar score mean?

Accepted Answer

It is a normalized indicator (max 100) based on moon phase, distance and key transits. Weather and pressure can still dominate results.

Question 2

Why are excellent days rare?

Accepted Answer

We enforce a deterministic monthly distribution: 3–4 excellent days and at most 8 good days per month.

Question 3

Does location matter for Tokyo?

Accepted Answer

Yes. Sunrise/sunset times and the moon’s position depend on latitude/longitude, which changes windows and the final score.
