How a birthday becomes a grid.

Your Driver is the day of the month, reduced to one digit. Born on the 15th? 1+5 = 6.

Your Conductor is the full date — day, month, year — added together and reduced. 15+3+1990 → 1+5+3+1+9+9+0 = 28 → 2+8 = 1.

Your Kua uses just the year. 1+9+9+0 = 19 → 1+9 = 10 → 1, then 11 − 1 = 10 → 1.

The Lo Shu Grid is a 3×3 square with numbers 1 through 9 in a fixed traditional arrangement. Every digit from your date of birth (plus your Driver and Conductor) lands on its cell. Multiple of the same digit stack as ×2, ×3, etc.

Sum any row, column, or diagonal → 15. That's why it's called a magic square.

The reading has four layers:

• Driver, Conductor, Kua. Three core numbers that shape your style, presence, and elemental alignment.
• Counts. A number appearing twice is amplified. Three times: dominant. Four or more: overload. Missing: an area to grow.
• Energy lines. Rows, columns, and diagonals where all three cells are present become "arrows" of strength. The reverse — all three missing — point to gaps.
• Personal year. A 9-year cycle: 1 (beginnings) → 9 (completion). Where you are in the cycle right now colors everything else.

The same Lo Shu Grid lives in many different people — a teacher, a CEO, an athlete, an artist. What you do with the pattern matters far more than the pattern itself.

Use the reading as a self-knowledge tool: "this is a tendency in me; how do I want to relate to it?" Not as a prediction or an excuse.

For the math fans: every operation is implemented in frontend/utils/loshu.ts if you want to see exactly how it works.
