Our exclusive 2017 calendar tracks the waxing and waning cycles of the moon. Beautiful hand-drawn pen and ink graphics are created by Katheren Belle. The dates used to chart the positions of the lunar phases are from the Circular published by the Nautical Almanac Office at the U.S. Naval Observatory. Useful for farmers, fishermen, teachers, children or anyone who wants to be more mindful of nature's rhythms. Printed with vegetable-based inks on heavy 100% recycled FSC paper.
