Lo Shu grid calculator
The Lo Shu grid calculator from API for Astrology (apiforastrology.com) turns a birth date into a nine-cell grid. Each cell stands for one number from 1 to 9. The grid shows which numbers are missing, which repeat, and which lines (planes) are full or empty.
The grid uses the birth date only, so the name does not change it. The name is asked because the same call also returns the name number. We do not store the details you enter.

Sample, not your result: John Doe, born Aug 15, 1990
The digits of the birth date, with the core numbers, fill the 3 by 3 grid. Empty boxes are the missing numbers. Your own result shows under the form.

How the Lo Shu grid is worked out
The grid is a magic square. Its top row is 4 9 2, the middle row 3 5 7 and the bottom row 8 1 6. Every row, column and diagonal adds up to 15. Each digit of the birth date, written as day, month and year, goes into the cell for that number. Zeros have no cell.
The bhagyank (destiny number, also called the conductor number) is added next. The mulank (birth day number, also called the driver number) is added only when the birth day has two digits. That way a day like the 6th is not counted twice.
A line is three cells in a row, a column or a diagonal. Many books call the lines planes or arrows, and there are eight of them. A line is read only when it is full or empty. Books differ on these rules, so the API states its rule in the answer.
Worked example: John Doe's grid
John Doe was born on August 15, 1990. Once the zeros are dropped, his date gives 1, 5, 8, 1, 9 and 9. Then his bhagyank 6 and his mulank 6 are added. So 1, 6 and 9 appear twice, and 2, 3, 4 and 7 are missing.
He has two full lines: the practical line (8, 1, 6) and the willpower line (9, 5, 1). No line is empty, so no other line is read.
Method and sources
Every number here comes from simple counting on the name and date you enter. So the same details always give the same result. The letter values and the counting rules are on the numerology conventions page.
The Lo Shu square holds the numbers 1 to 9 once each. Every line adds to 15, as shown by Wolfram MathWorld. Each row, column and main diagonal of a 3 by 3 magic square adds to 15. See Encyclopaedia Britannica.

Common questions
All questionsWhy are the bhagyank and mulank added to the grid?
It is common Indian practice to place them with the digits of the date. Not every book does this, so the API names its rule in a field called basis. The mulank is added only for a two-digit birth day. A day from 1 to 9 is already in the grid.
The Lo Shu grid in the glossaryWhat does a missing number mean?
A missing number is one that no digit of the date, the bhagyank or the mulank fills. Indian numerology reads it as something that may take more effort. The API returns a short reading for each missing number.
Missing numbers in the glossaryWhat does a repeated number mean?
The grid shows how many times each number appears. The API returns a short reading for each number that appears twice or more. In John Doe's grid, 1, 6 and 9 each appear twice.
Repeated numbers in the glossaryWhy are some lines not shown?
A line is read only when all three of its cells are filled, or none are. A line with one or two cells filled says nothing clear either way, so it is left out. That is why one grid may show several lines and another none.
Lines of the grid in the glossaryCan I show the Lo Shu grid in my own app?
Yes. Sent with your own API key, POST /v1/profile returns the grid as JSON. You get each cell with its count, and every digit placed with where it came from. You also get the missing and repeated numbers and the full or empty lines. The same call returns the mulank, bhagyank and name number. One live call uses 3 reading credits.
