The ECOlogical Calendar is the first calendar to focus on the natural structure of the year. The ECOlogical Calendar highlights the often-overlooked primary division of the year, the 4 astronomical seasons. Our ECOlogical Calendar is the first calendar to be divided into four seasons, each beginning with either a solstice or equinox. It also illustrates a multitude of other natural annual phenomenon - moon phases, variation between tides, meteor showers, seasonal constellations and much more.
