Lo Shu Grid Calculator

The Lo Shu grid arranges the digits of your birth date on a 3x3 square. Repeated digits show where a trait is emphasised; absent digits show where it is not. Nothing here is hidden - the grid is just your own date, rearranged.

Your date of birth

The grid is built from the date alone. The name is used only to address the result.

Calculation method

This setting only affects numbers taken from the letters of a name. Your Lo Shu grid comes entirely from the date, so it is identical under either system.

Use the full date, including the century. A year written as 87 instead of 1987 produces a different set of digits and therefore a different grid.

The grid starts with your birth date, then adds two reduced numbers.

This is worth saying plainly, because the presentation invites the opposite conclusion. A 3×3 square of planets looks like a reading of you. It is a tally of digits — and once you have seen the five steps, you can produce your own grid on paper in under a minute and check anything a practitioner tells you about it.

Worked example: 25 March 1987
StepWhat you doDigits so far
1Write the date as DDMMYYYY.2 5 0 3 1 9 8 7
2Drop every zero. The square has cells for 1 to 9 only, so a zero has nowhere to go.2 5 3 1 9 8 7
3Add the Mulank — the day, 25, reduced: 2 + 5 = 7.2 5 3 1 9 8 7 · 7
4Add the Bhagyank — the whole date: 2 + 5 + 0 + 3 + 1 + 9 + 8 + 7 = 35, and 3 + 5 = 8.2 5 3 1 9 8 7 · 7 8
5Count how often each digit from 1 to 9 appears. That count is the grid.7 twice, 8 twice, 4 and 6 never

So this grid has two repeated numbers, 7 and 8, and two missing ones, 4 and 6. Read across the fixed square, the top row holds no 4, one 9 and one 2; the middle row holds one 3, one 5 and two 7s; the bottom row holds two 8s, one 1 and no 6. Every one of those statements is a fact about the date 25/03/1987, and about nothing else.

Steps 3 and 4 are the part that differs between books. Adding the Mulank and Bhagyank to the grid is the common Indian method and the one used here; several Western treatments plot only the digits of the date. That single choice changes which numbers count as missing for a great many people, and no source resolves it — so if another calculator gives you a different grid, this is almost always why.

Where each number sits, and which planet it carries.

The positions are fixed for everyone. They come from the classical magic square in which every row, column and diagonal totals fifteen — the arrangement is mathematical in origin, and the planetary rulerships were mapped onto it afterwards by the Indian tradition.

The Lo Shu square, with the plane each row is read as
RowLeftCentreRight
Mind plane4 · Rahu9 · Mars2 · Moon
Emotional plane3 · Jupiter5 · Mercury7 · Ketu
Practical plane8 · Saturn1 · Sun6 · Venus

Read downwards instead of across and the same nine cells give three more lines: 4–3–8 on the left, 9–5–1 through the middle, and 2–7–6 on the right. A line counts as complete only when all three of its numbers appear at least once in your date.

The four planes most readings are built on.

A plane is just a line of three cells. A complete line is treated as an area that runs without much effort; a broken one as an area that needs a deliberate substitute. In the worked example above the emotional plane 3–5–7 is complete and the middle column 9–5–1 is complete, while the mind plane is broken by the absent 4.

Mind plane — 4, 9, 2

The top row. Read as thinking, memory and imagination: Rahu's unconventional angle, Mars's decisiveness, the Moon's sensitivity to what other people are feeling. Complete, it is read as someone who plans, decides and reads the room in one motion.

Emotional plane — 3, 5, 7

The middle row. Jupiter, Mercury and Ketu — belief, adaptability and detachment. It is the line most often read for how someone recovers from a setback rather than how they feel day to day.

Practical plane — 8, 1, 6

The bottom row. Saturn, Sun and Venus: patience with detail, willingness to lead, and care for comfort and relationships. Broken, it is described as ideas outrunning execution — which is a description, not a diagnosis.

The middle column — 9, 5, 1

Mars, Mercury and Sun, read top to bottom as will: the line that carries an intention from impulse through adjustment to action. Several Indian texts single it out under a separate name and treat a complete 9–5–1 as the most useful thing on the grid.

Books disagree about how many planes there are

Three rows, three columns and two diagonals give eight lines in total, and different traditions promote different subsets of them to named planes. Some count three, some four, some six. That variation is not a detail that has been lost — it is a sign that the naming is interpretive rather than fixed, and it is worth knowing before anyone quotes a plane at you as though it were a measurement.

What the grid cannot tell you.

Your decade decides much of it

Every date from 1900 to 1999 carries a 1 and a 9 in the year, so almost nobody born in that century has either as a missing number. Every date from 2000 onwards carries a 2 and loses the 9 entirely. A child born in 2011 will show a very different grid from a parent born in 1979 for reasons that are entirely calendrical.

Dropping zeros is a convention

The square has no cell for 0, so zeros are discarded. Someone born on 05/09/2003 therefore contributes fewer digits than someone born on 27/12/1978, and will show more missing numbers simply because their date is shorter once the zeros go.

It is not a prediction

Nothing in the grid describes an event, a date or an outcome. The tradition uses it as a prompt for reflection and, in the Indian form, for choosing a remedy. Treat any reading that turns a missing number into a warning about your health, marriage or money with suspicion.

Remedies are not fixes

Classical remedies for a missing number are ordinary disciplines — a weekly practice, a donation, a change in routine. They are worth what any deliberate habit is worth. Nobody should charge you a fee to remove a number from a square that your own date of birth put there.

Common Lo Shu grid questions

Which date do I enter?

Your date of birth, in full. The grid uses every digit of the day, month and year, so a two-digit year changes the result.

What does a missing number mean?

It means that digit does not appear in your birth date. Traditionally it is read as an area that needs conscious attention rather than one that comes naturally. It is not a fault or a prediction.

Why do some grids show the same number three times?

Because that digit genuinely occurs three times in the date. Repetition is common and simply indicates emphasis.

Is the Lo Shu grid the same as my Mulank?

No. Mulank is the reduced day of birth, a single number. The Lo Shu grid uses the whole date and shows a pattern rather than one value.

The rest of the numerology set.

Each of these answers a different question from the same birth date or name. The grid pairs most naturally with the date-of-birth calculator, which shows the Mulank and Bhagyank working in full.

One number is a fact. The set is a reading.

This page computes one number and shows its working, which is what it is for. The Numerology Report takes the same name and date and reads the whole set against each other — the two date numbers, the three name numbers, the Lo Shu grid, any karmic debt before reduction, and where the nine-year cycle currently sits. It is the one page in this set that costs anything, its price is in coins rather than rupees, and every figure inside it can still be checked free on the calculator that computes it.
