How the score is built
The engine returns five dimension scores and an overall weighted score. Nothing in it is random, and the factors behind each dimension are listed with the result:
- Day Master elements. Whether the two element types generate each other, match, or control each other.
- Day branches. Combination, clash, harm, punishment or no relationship — the strongest single signal.
- Useful elements. Whether one chart’s balancing elements appear in the other’s Day Master.
- Ten God distribution. How much output and wealth each chart carries.
- Wealth-route overlap. Whether the two charts favour the same working style.
Different schools use different compatibility methods — some compare the Year branches or the spouse palaces, some only compare Day Masters. This tool uses one documented method and shows its inputs, so its output can be read as one opinion rather than the answer.
Questions people ask
How is the compatibility score calculated?
Both charts are computed first, then compared on five measured dimensions — money, communication, family, children and the long term — and combined into one number out of 100. Each dimension carries its own note, so you can see which ones pull the score down.
Does a low score mean we should not be together?
No. It measures how two sets of traditional markers sit against each other, not how two people behave. A chart is a lens for a conversation, and the number is the least useful part of it — the dimension notes are where the information actually is.
Do both people need birth times?
The dates and birthplaces are required; the hours are optional and can be marked unknown. Without hours, the comparison falls back to three pillars per person, which makes the reading coarser but still usable.
Is this the same as zodiac compatibility?
No. Zodiac compatibility compares one branch each — a twelfth of the picture, and the part everyone shares with millions of strangers. This compares full charts: day masters, element balance and the structural relations between branches.
