The 2021 Maria Thun Biodynamic Calendar, now in its 59th year, adapted for North American (Eastern Standard Time) dates and times.

This useful guide shows the optimum days for sowing, pruning, and harvesting various plants and crops, as well as working with bees. It includes Thun's unique insights, which go above and beyond the standard information presented in some other lunar calendars. It is presented in colour with clear symbols and explanations.

The almanac includes a pullout wallchart that can be pinned up in a barn, workshop or garage as a handy quick reference.
