Lo Shu Grid Calculator

What the Lo Shu grid is

The Lo Shu square is a 3×3 arrangement of the numbers 1 to 9 in which every row, column and diagonal adds up to 15. According to Chinese legend it appeared on the shell of a turtle emerging from the Lo river, and it has been used for centuries in feng shui, calendar systems and, more recently, numerology.

The fixed layout looks like this:

In Lo Shu numerology, each position represents a quality: communication, intuition, imagination, discipline and so on. Your date of birth fills some positions and leaves others empty. The result is a quick visual summary of where your natural strengths sit and which areas may need more conscious attention.

How the grid is built

AstroAnktara follows the approach most common in Indian numerology:

1. Take every digit of your date of birth and ignore zeros.
2. Add your Moolank (driver number, from the day) and Bhagyank (conductor number, from the full date).
3. Place each digit in its position on the square. If a digit appears more than once, it is written that many times in the same box.

Let's build the grid for 14 March 1992.

• Birth date digits: 1, 4, 3, 1, 9, 9, 2 (the zero in 03 is ignored).
• Moolank: 1 + 4 = 5.
• Bhagyank: 1 + 4 + 0 + 3 + 1 + 9 + 9 + 2 = 29 → 11 → 2.
• All digits for the grid: 1, 4, 3, 1, 9, 9, 2, 5, 2.

That fills the grid as follows. The top row reads 4, 99, 22. The middle row reads 3, 5, and an empty box for 7. The bottom row has empty boxes for 8 and 6, with 11 in the middle. So 1, 2 and 9 each appear twice, while 6, 7 and 8 are missing.

Reading missing and repeated numbers

Each number has a theme. In the grid, its presence suggests an available strength, repetition suggests that strength is emphasised (sometimes too much), and its absence suggests an area for growth.

• 1 self-expression and communication
• 2 intuition and sensitivity
• 3 imagination and memory
• 4 organisation and discipline
• 5 emotional balance and willpower (the centre of the grid)
• 6 home, family and responsibility
• 7 learning through experience
• 8 attention to detail and practical management
• 9 ambition, intelligence and idealism

Your report explains each missing number in your grid and describes your most repeated numbers. Keep in mind that missing numbers are extremely common. Most grids have three or four empty boxes, and the interpretations are written as invitations to grow rather than as warnings.

A note on 9: almost everyone born between 1900 and 1999 has at least one 9 from the year. People born from 2000 onward often have no 9 at all, so a missing 9 is far more common in younger charts and carries less weight.

Planes and arrows

The rows, columns and diagonals of the grid are called planes or arrows. When all three numbers on a line are present, the plane is complete and is read as a well-developed area of life. When all three are missing, it is read as an area that may need support.

• Mental plane (4-9-2): thinking, planning and memory
• Emotional plane (3-5-7): feeling, sensitivity and spirituality
• Practical plane (8-1-6): material and physical skill
• Thought plane (4-3-8): planning before acting
• Will plane (9-5-1): determination and persistence
• Action plane (2-7-6): turning ideas into action
• Golden arrow (4-5-6) and silver arrow (2-5-8): the two diagonals, often described in Indian numerology as especially fortunate when complete

In our example, the mental plane (4, 9, 2) and the will plane (9, 5, 1) are both complete, suggesting a sharp, organised mind backed by determination.

Differences between practitioners

Lo Shu numerology has several schools, and you may see slightly different grids elsewhere. The most common differences are:

• whether the Moolank is added when the birth day is a single digit (some add it only for days 10 to 31, to avoid counting the same digit twice)
• whether the Bhagyank is added at all
• the exact names and interpretations of planes

AstroAnktara always adds both numbers and shows the driver and conductor at the top of the report, so you can mentally remove them if your teacher uses a different rule.

What to do with your grid

Use the grid as a map of tendencies. If 4 is missing, for example, a simple weekly planning habit may make a real difference. If 5 is repeated, notice whether strong willpower occasionally turns into stubbornness. Combine the grid with your Moolank and Bhagyank for a fuller picture, or compare a phone number's digits with your grid using the mobile number numerology tool.
