Celtic astrology is based on the Druidic teachings of the Celtic Druids. The Druids believed the trees to be sacred as they symbolized life, death and renewal. Much like many other ancient cultures, they observed that children born during certain seasons and cycles developed similar qualities in their personalities. However, where many other cultures based their astrological calendars on the stars, the Druids linked them to the moon and based their calendar on the lunar year. The Celtic astrological calendar has thirteen signs that correspond to the thirteen lunar months, each with 28 days. December 23rd is the extra day and is known as Nameless Day. The most popular form of Celtic astrology is Celtic Tree astrology in which each of the months is tied to a tree. Each of the trees also corresponds to animals, colors, ogham or runes, and a gemstone.
