For fun. The biodynamic calendar is winemaker lore, and a 2016 blind-tasting study in New Zealand found no difference between day types. Earth's Pulse runs on NOAA's geomagnetic Kp index, the same number most Schumann resonance sites use, and the moods are the energy crowd's reading of it, not science. The Earth is not telling you to open the Sauternes. It isn't telling you not to, either.
