Your Personal Month plus the calendar day. Used for daily rhythm, signing dates, picking a launch day. Treat it the way a sailor treats the wind report: useful at the margin, not a substitute for knowing what you are doing.
Your Personal Year plus the current calendar month, reduced to a digit. Used for medium-grain planning. Some readers swear by it; others find it noisy compared to the Personal Year. If a single month feels uncharacteristic for your year, this number often explains why.
A single digit (1 through 9) derived by adding your birth day, birth month and the current calendar year, then reducing. It describes the dominant flavour of the year as you experience it. Year 1 begins something. Year 9 closes something. The pattern repeats every nine years.
ExampleBorn 14 March, currently 2026: 1+4+3+2+0+2+6 = 18, then 1+8 = 9. A closing year.
Calculated from the consonants of your full name. Where the Soul Urge is interior, the Personality number is the impression you leave on a stranger in the first five minutes. Useful when read in the same breath as the Soul Urge to see the gap between what you feel and what you project.
One of four extended life stages, each governed by a single number derived from the birth date. The first Pinnacle covers roughly the first thirty years; the last carries you to the end. Pinnacles are slower than Personal Years and describe shifts in what life is asking of you.
Greek philosopher of the sixth century BCE whose followers held that number is the principle of all things. The Pythagoreans treated arithmetic, music and the order of the cosmos as one subject. Modern numerology takes its name and its appetite for symbolism from them, though most of the actual techniques are much later.
The dominant Western letter-to-number scheme, mapping A through Z onto the digits 1 through 9 in order, wrapping around. Most English-language name readings use it. Its main strength is simplicity. Its main weakness is that it ignores phonetic weight.
