About 3,000 years ago, when man lived in close relationship with nature, the Celts used trees as markers of time. Originating and designed from this principle, this Tree Calendar features the division of time based on the knowledge of trees and lunar cycles. This annual calendar is divided into 13 moons, each associated with a tree, which are themselves fragmented into a number of complex divisions. Four trees are considered as cardinal or core trees:
the oak tree, the symbol of life force,
the birch tree, bearer of light for the initiated,
the olive tree, friend of wisdom,
the beech tree, the one who knows how to wait.
Sixteen other trees, always evocative of certain virtues, are referent trees, or symbolically guiding trees: hazel, rowan, maple, walnut, chestnut, ash, hornbeam, fig, apple, fir, elm, cypress, cedar, pine, willow, lime. Two trees have a special status: the yew, considered the tree of death, and the poplar, considered the conqueror of doubt.
The trees should be arranged in a perfect circle, symbolising the human soul.
Each tree corresponds to a time of the year, so you can determine your "tree sign" according to your day of birth and find out which tree is your guardian.
