Traditional astrology has guided humanity for at least a thousand years. So it’s time for an upgrade—and Dayology is here to offer it. We’ve long consulted THE SUN SIGNS to understand our outer selves. Now, with The DAY RAYS, we can explore the intentions that guide us from within. Dayology blends these two dimensions into one simple, creative path.
While traditional astrology relies on the exact time and location of birth to construct detailed horoscopes, Dayology takes a simpler approach. By blending the day of the week and zodiac sign, it offers a creative and accessible path to self-understanding — one that honors ancient wisdom while inviting modern exploration. Dayology offers a bold new interpretation – one that doesn’t just read your chart for this lifetime, but rewrites the exquisite map of personhood and soul.
In Dayology, everyone is born with two basic influences: THE DAY RAY and THE SUN SIGN.
 THE DAY RAY |  THE SUN SIGN |
THE DAY RAY represents the soul—the inner source of inspiration, values, and purpose. It reflects the spiritual tone of the weekday on which we are born and its planetary ruler.
THE SUN SIGN represents the personality—the outer expression of our character, behavior,
and style. It shows how we present ourselves to the world and engage with life’s challenges.
Dayology combines these two energies into a highly creative framework of eighty-four types known as THE DAYOLOGY SIGNATURES — each expressing distinct abilities and opportunities to live rich and meaningful lives. This innovative system is grounded in the traditional astrological concept of planetary rulership, thoughtfully reinterpreted for the present day. More about Dayology can be found in the materials listed in The Overview of Basic Dayology Principles.
