The annual Biodynamic planting guide and calendar put out by Kimberton Hills Camphill Village in PA. Full of interesting articles, beautiful art, and most importantly a month by month guide to growing. The calendar indicates days best suited to various types of work and cycles of growth on the farm according to Biodynamic observations and is meant to be used in concert with your own common sense and an eye toward the weather.. We use this every year. Great as a year to year reference of sowing/planting times, weather, and notes. 

"This Calendar has many aspects: a basic introduction to astronomy, a simple ephemeris, a planting guide, a star map, aid for following the movement of the planets in the night sky, and articles by ten different authors. All of these attempt to provide a true picture of the world outside us and ideas to assist in developing a healthy relation to that world."
