What is the lo shu grid calculator?
The Lo Shu grid is a 3×3 magic square in which every row, column and diagonal sums to 15. Its origin is Chinese, but it was absorbed into Indian numerology long ago and is now read alongside mulank and bhagyank, with each of the nine cells assigned to a graha. To build your grid, every non-zero digit of your date of birth is dropped into its matching cell, and the Indian variant additionally adds your mulank and bhagyank.
What the reading keys off is not the digits themselves but their distribution. A number appearing more than once intensifies the qualities of its planet. A number absent entirely marks a quality the tradition says has to be consciously developed rather than one you were handed. Because a date of birth can supply at most eight digits into nine cells, everyone has missing numbers — that is the normal case, not a defect.
Complete rows, columns and diagonals form the planes and arrows: the mental plane (4-9-2), the emotional plane (3-5-7), the practical plane (8-1-6), and the arrows of determination (4-5-6) and spirituality (2-5-8), among others. A complete line is read as a pronounced strength; a completely empty one is read as its counterpart. This calculator shows the filled grid, the counts, the missing and repeated numbers, and every plane and arrow that either completed or stayed empty.
How this calculator works
- 1
Enter your date of birth
That is the only input. No name, birth time or place is needed for the Lo Shu grid.
- 2
Digits are placed in the grid
Each non-zero digit of the day, month and year goes into its cell in the magic square. Zeros are not placed — they have no cell.
- 3
Mulank and bhagyank are added
The Indian variant of the grid adds your root and destiny numbers on top of the raw digits, which is what this calculator does.
- 4
Planes and arrows are detected
The grid is scanned for complete and empty rows, columns and diagonals, and each is reported with its traditional meaning.
Frequently asked questions
It marks a quality associated with that cell's planet that your date did not supply. The tradition reads it as an area to develop deliberately rather than as a flaw. Since a date yields at most eight digits, missing numbers are universal.
Repetition intensifies that number's planet. Moderate repetition is read as strength; heavy repetition is read as excess of the same quality, which has its own downside.
They are the complete rows, columns and diagonals of the grid. Rows are the mental, emotional and practical planes; the diagonals give the arrows of determination and spirituality. A complete line indicates a pronounced strength, an entirely empty one its opposite.
Its origin is Chinese, from the legend of the turtle in the river Lo. Indian numerology adopted it and layered its own planetary correspondences and the mulank/bhagyank addition on top, which is the version used here.
The birth grid never changes. Some practitioners also build a name grid or a current-year grid, which do change, but those are separate from the fixed birth grid this calculator produces.
No. The grid is computed on our own servers, is completely free, and requires no login.

Missing numbers are normal. What matters is which ones, and what your kundli says about them — that takes an astrologer.
