This useful guide shows the optimum days for sowing, pruning, and harvesting various plant-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 color with clear symbols and explanations.

The calendar includes a pullout wall chart that can be pinned up in a barn, shed or greenhouse as a handy quick reference.
