Lunar Data

Lunisolar Equilibrium

Live lunar mechanics — phase, illumination, distance, libration, and nodal drift derived from your local clock. The Selene calendar itself lives in its own pillar.

3D Sphere % — linear with phase angle (uniform 6.25% per 32nd). Constant rate, ideal for time-keeping.

2D Circle % — Earth-view illumination = (1 − cos θ) / 2. Non-linear: fast near quarters, slow near new/full.
