How the cycles are counted
The personal year number adds your birth month, your birth day and the current calendar year, then reduces the total. It runs on a nine year loop, so a one year begins something that a nine year finishes, and the pattern repeats for as long as you keep counting.
Personal months and personal days are built on top of the personal year, which is why the smaller cycles only make sense once you know the larger one.
Longer arcs: pinnacles and challenges
Pinnacles and challenges divide a life into four long phases with their own numbers, calculated from the birth date. They change every few decades rather than every year, which makes them the part of the system people find most useful in hindsight.
The written explanations in the numerology library cover how these longer arcs interact with the core numbers.
Reading a season without predicting events
Cycle readings describe a quality of time, not an itinerary. A four year is not a promise of hard work arriving; it is a description of the kind of effort that tends to pay off if you are already doing it.
For something that changes daily rather than yearly, the daily numerology decoder works out the universal day number for any date on the calendar.
