The Celtic calendar consists of 13 months and is based on the lunar cycle. Each month includes 28 days, except for one, which has 24 days. The 365th day — December 23 — is called the Nameless Day, and its representative tree is the fir tree. It was on this day that Celts would adorn the tree — thus the custom of decorating the Christmas tree was born. The Druids considered the forest, the trees among which they had to live, to be of great importance. They argued that each person, like a tree, has certain traits, strengths and weaknesses. The Celtic Calendar coin will take you to a world of ancient rituals and traditional beliefs. All Celtic patterns are distinguished by their filigree and artistry, and are extremely popular in the modern world.
