Numerology and Astrology
Twelve, ten, zero and master numbers in astrology and modern numerology.
Start here · Essential guide
Why twelve organises the zodiac, months and hours, how the Moon's cycle likely explains it, and why astrology and numerology remain beliefs, not tested predictions.
How master numbers such as 11, 22 and 33 entered numerology, who popularised them in the early 20th century, and why the concept is modern rather than ancient.
How zero works in astrology as a coordinate convention, from 0 degrees Aries to the cardinal points and ayanamsa, and why it is a measuring rule, not a prediction.
Why ten came to stand for completion: ten fingers and the decimal system, the Pythagorean tetractys, the Ten Commandments and numerology's reduction of ten to one.
