How it works
This site does not roll dice. The articles below set out every rule it uses — from turning a Gregorian birth date into four pillars, to why a name's strokes are counted the Kangxi way. Read them and you can reproduce any result by hand.

Five Elements and Day-Master StrengthGeneration and control among Wood, Fire, Earth, Metal and Water, why the month branch weighs most, how strength is judged, and how the favourable element is chosen.
The Five Grids of a NameThe complete Five Grids method — the formula for each grid, the 81 numerology values, the Three Powers, and why a single-character name always gives an Outer grid of two.
