Why the square holds more digits than the date
Because the calculation includes more than the date. Its digits are joined by the digits of four additional numbers derived through summing. The total comes to twelve-fifteen digits instead of eight — hence the fuller square.
The logic in one example
The date 14.03.1991 has eight digits, and some — sevens, say — appear nowhere in it. After the summing, sevens and other absent digits can appear. A cell stops being empty.
Why it isn’t rigging
The method is built this way by design: the date gives the raw material, the derived numbers show how the potential unfolds. The rules are fixed and identical for everyone — never adjusted to the person.
Zeros don’t count
The square has nine cells — digits one through nine. Zeros from the date have no box and drop out. That’s why people born in the 2000s often have sparser squares.
Different calculators differ
That’s normal and traces to the additional-number rules: schools disagree on details. If your square differs from another service’s, ask Viki for the step-by-step and compare methods, not results.
Ask for the steps — it all adds up.
