Welcome, dear reader! There’s a certain enchantment that surrounds Celtic astrology, a sentiment I’ve deeply felt each time I’ve explored its realms. Unlike other astrological systems where stars and planets are the primary focus, the Celts turned to the earth, specifically the trees, for their cosmic insights. These towering beings, with roots deep in the ground and branches reaching towards the heavens, serve as symbols for the various signs in Celtic astrology. Their steadfast nature and seasonal transformations provide a unique lens through which we can understand our own personalities and destinies. It’s this intertwining of nature, spirit, and star that has made me profoundly fascinated with the subject. Join me as we journey through the Celtic forests, where each tree tells a story and every whisper of the leaves reveals a piece of our soul’s journey.

Celtic Astrology: The Ancient Wisdom of the Druids

The Celts, an ancient culture that spread across Europe, have long been a source of fascination.

Among their many intriguing traditions, Celtic astrology stands out for its unique approach, deeply rooted in the natural world and the teachings of the Druids.

A Brief Overview

Celtic astrology springs from the Druids, revered figures in Celtic cultures of the British Isles and Western Europe. As priests, scholars, and magicians, the Druids were the guardians of knowledge, with a worldview deeply connected to the land, trees, and celestial cycles. Venturing into Celtic astrology is akin to journeying into the Druids’ spiritual landscape, a realm where nature and mysticism merge seamlessly.

The Tree Calendar

Distinct from the familiar 12-sign Zodiac, the Celtic tree calendar comprises 13 lunar divisions. Each division, rather than being tied to constellations, is associated with a particular tree, each embodying its own set of characteristics and energies. Trees were sacred symbols in Celtic traditions, representing life, death, and cycles of renewal.

The Role of Animals

Animals, revered as spirit guides, are central to Celtic astrology. Each tree sign has an associated animal that offers further insights into one’s character and potential. The Alder tree (March 18 – April 14), for example, aligns with the fox, an animal known for its cunning and adaptability.

These animals not only symbolize certain traits but also serve as guides, helping individuals navigate challenges and harness their innate strengths. Reflecting on these spirit animals can provide deeper self-understanding and direction.

Lunar vs. Solar

Celtic astrology’s foundation is the moon and its phases, in contrast to many astrological systems that revolve around the sun. The moon, with its ever-changing form, resonates with the cyclical nature of life, mirroring birth, growth, decay, and rebirth. This lunar-centric perspective celebrates the feminine divine and the mysteries of the subconscious.

The Sacred Number 13

Thirteen, often viewed with suspicion in other traditions, is sacred in Celtic astrology. Representing transformation and rebirth, the 13 lunar cycles and tree signs offer a more fluid and nuanced understanding of human nature and potential. This contrasts sharply with the usual negative connotations surrounding the number in many cultures.

The Ogham Alphabet Connection

The Ogham, an archaic Celtic script, intertwines intimately with Celtic astrology. Each tree sign corresponds to a unique Ogham symbol. Druids often used these symbols in rituals, inscribing them on stones or wood for protection, guidance, or divination. Delving into the Ogham provides another layer of insight and connection to ancient Druidic practices.

Druidic Wisdom and Rituals

Rituals aligned with lunar cycles were paramount in Druidic practices. They believed that specific moon phases were propitious for distinct kinds of magic or endeavors. The waxing moon, symbolizing growth and expansion, was deemed ideal for launching ventures or planting seeds, both literally and metaphorically.

Compatibility and Relationships

Similar to other astrological systems, Celtic astrology offers profound insights into compatibility. By juxtaposing one’s tree sign with another’s, one can glean the dynamics of a relationship, whether it’s romantic, friendly, or professional. Such insights can be instrumental in fostering understanding and harmony in relationships.

Modern Interpretations and Revival

In the modern era, as interest in ancient and pagan traditions resurges, Celtic astrology is experiencing a renaissance. Modern Druids and spiritual seekers are integrating and adapting these ancient teachings, often blending them with other spiritual practices, creating a rich tapestry of understanding and belief.

Celestial Observations

While the Celtic tree calendar is undeniably a form of astrology, it doesn’t focus on planetary movements in the same detail as Western or Vedic astrology. Instead, its essence lies in observing the natural world, understanding the rhythms of the moon, and tuning in to the energies of the earth.


Celtic astrology offers a unique lens through which we can view ourselves and our place in the world. It’s an evocative system, stirring the soul with its poetic connections to trees, animals, and lunar cycles. By exploring its depths, we’re not only gaining insights into our personalities and destinies but also reviving the age-old wisdom of the Druids.
