The Celtic zodiac is based on the cycle of the moon with the year divided into 13 lunar months, each associated with a tree considered to be sacred to the Druids. The 13 tree months each correspond to a tree, a letter of the Ogham alphabet, a guardian animal and a Celtic god. This chart provides all information, as well as a detailed character analysis for each of the 13 personality types. It is especially interesting to compare the Celtic moon cycles with the traditional zodiac sun cycle.
