GreenCal.Day.Moon (GreenCal v0.1.1)

Lunar part of a GreenCal.Day.

Summary

Types

t()

The three trend fields are the three independent lunar cycles: :trend follows the declination (ascending/descending — the cycle biodynamic sowing calendars use), :illumination_trend the phase (waxing/waning), :distance_trend the orbit (approaching/receding).
