Business numerology is read through a small set of defined terms: the mulank or birth number taken from the day of birth, the bhagyank or destiny number taken from the full date, the name number produced by a letter-to-digit table, the compound number sitting behind every single digit, and the Lo Shu grid built from a date of birth. This glossary defines each of those terms as this tradition uses them.
The core numbers taken from a date of birth
Mulank (birth number)
The mulank is the day of the month a person was born, reduced to a single digit; the month and year are never used. Days 1 to 9 stay as they are, and a two-digit day is summed, so the 28th gives 1. The same number appears in this tradition as moolank, driver, psychic number, day number or birth number. It is read as temperament, communication style and self-image. The core number calculator produces it from a date.
Bhagyank (destiny number)
The bhagyank is the total of every digit of a full date of birth written day-month-year, reduced to a single digit, with the year always written in four figures because 1984 and 84 do not reduce alike. It is also called the conductor, destiny number or life path. Practitioners hold that it describes life purpose and career ceiling, and that unlike a name it cannot be altered afterwards.
Kua number
The kua is derived from the birth year alone and is the only core number in this tradition that depends on gender. The digits of the year are reduced to one digit; for men that digit is subtracted from 11, for women four is added, and the result is reduced again. One source calls it the major game-changer of a chart; another values it at roughly a fifth of the reading.
Reduced number (digital root)
Reducing means adding the digits of a number repeatedly until a single digit between 1 and 9 remains. Zeros are dropped and change nothing, and the order of addition does not affect the final digit. Most of this corpus treats 10 as reducing to 1, though one book system deliberately stops at 10 and reads it as a value in its own right rather than as a 1.
Compound number
The compound number is the two-digit total a name, date or phone number reaches before the final reduction. This tradition holds that the compound carries the hidden layer and the single digit the public one, so a 7 arriving from 16 is not read as the same 7 arriving from 25. Sources disagree on where the table stops — one at 52, another at 78, while practitioner sources use compound numbers well beyond both.
Master number
A master number is a total kept at two digits instead of being reduced. Which totals qualify is genuinely disputed here: the most common practitioner position is 11, 22 and 33; one source names 11 and 22 only; one book adds 44; another names 11, 22, 33, 55, 66, 77 and 88 while excluding 44. One classical compound table reads 11 as ominous and 22 as a warning, flatly against the master reading.
Karmic debt number
The karmic debt numbers are 13, 14, 16 and 19, and this is one of the few points where the practitioner and book sources agree exactly. The method tests for them at the two-digit stage, before reduction, because reducing hides them — 13 becomes a 4, 16 a 7, 19 a 1. One classical table dissents, reading 13 as not unfortunate and 19 as outright favourable.
Age-phase switch
The age-phase switch is the point at which the bhagyank is held to overtake the mulank in influence, without either number disappearing. The threshold is not agreed: several practitioner sources say 33, others say 35, one book says 35 to 40, and one says 40 give or take five years. The practical reading offered is to attempt genuinely new ventures before the switch rather than after it.
Letter systems and the numbers taken from a name
Chaldean system
The Chaldean table assigns each Roman letter a value from 1 to 8, with no letter carrying 9; the stated reason is that 9 was held sacred and reserved. It is the default across this corpus, described as the most widely followed for name work and as derived from the force of articulation. Every source here places H at 5, and the corpus notes that tables published elsewhere putting H at 8 do not appear in it.
Pythagorean system
The Pythagorean table runs A to I as 1 to 9, J to R as 1 to 9 again, and S to Z as 1 to 8, so every letter carries a value and 9 is in use. It appears here as the minority system, used mainly by the Western sources, and it produces a different total for the same name. Practitioners in this tradition treat it as a comparison view rather than the working table.
Name number (naamank)
The name number is the total of the letter values of a name, reduced to a single digit and reported alongside its compound. The full name gives what several sources call the expression number, while the first name alone is computed separately because it governs day-to-day circles. This tradition holds that a name number is never read alone — it is judged only against the mulank and bhagyank. The business name analyzer shows both totals.
Soul urge number
The soul urge, also called the soul number, is the total of the vowels of a name only, read as inner motive — what a person or company is from the inside. Sources split on the boundary cases: one treats Y as a vowel when it sounds like E and W as a vowel after D or G, another prefers charting Y both ways, and no Chaldean source in this corpus rules on the question at all.
Personality number
The personality number, sometimes called the outer expression, is the total of the consonants of a name, read as the outward face — how the world sees the person or the brand. It uses the same letter table as the full name number, and this corpus applies it to company names as well as personal ones. One book builds a further number by adding the unreduced vowel and consonant totals together.
Trading name versus registered name
The registered name is the legal entity name; the trading or brand name is what customers actually use. The majority position here strips government-conferred suffixes such as Private Limited, LLP and Ltd — the stated test being whether the government gave it to you or you wrote it yourself — and counts everything else. A minority source counts "Limited" inside the total. Practitioners rank the name in daily use first.
Name correction
Name correction is editing the spelling of a name so its total lands on a chosen number: adding a middle initial, doubling a letter, dropping a trailing S, or adding a descriptive word. This corpus records that no legal document need change, and that a corrected spelling is activated through cards, e-mail addresses, signatures and social profiles. It also warns plainly against self-editing a name from half-watched instructions.
The Lo Shu grid
Lo Shu grid
The Lo Shu grid is a fixed three-by-three layout — 4-9-2 across the top, 3-5-7 in the middle, 8-1-6 along the bottom — into which the digits of a date of birth are dropped, each into its own permanent cell. Zeros have no cell and are discarded; repeats are stacked. Most sources also enter the mulank, bhagyank and kua. The Lo Shu Grid calculator lays a date out this way.
Missing number
A number is missing when its cell holds nothing after the birth digits and the auxiliary numbers have been placed. This tradition reads a missing number as a weakened area rather than an absent trait, and one book stresses that the quality simply needs developing. Everyone is said to have at least one. Missing 5 is described as by far the most common, and 5 and 6 missing together as the most consequential pairing.
Repeated number
A repeated number is a digit appearing more than once in the grid, written again into the same cell each time. The method reads repetition as intensity rather than as extra luck, and the count matters: a single 7 is treated as neutral for the health reading while two or more is treated as a weak signal. The same logic drives the phone-number rule against any digit occurring three or more times.
Planes (the eight lines)
The grid's three rows, three columns and two diagonals are called planes or lines, and a line is complete when all three of its cells are filled from any source. This corpus names a thought plane, a will plane, an action plane, a mental plane and a practical business row, and ranks the 4-5-6 and 2-5-8 diagonals highest. Which lines complete is held to matter more than how many do.
The lottery rule
The lottery rule describes what happens when the mulank, bhagyank or kua supplies a digit the date of birth itself did not contain. Each of the three is called a lottery: it is "filled" when it opens a previously empty cell, and "empty" when that digit was already present. One cell yields one prize only, so two auxiliary numbers landing on the same empty digit still count once.
How numbers relate to one another
Planetary rulership
Every digit is tied to a planet, and this map is the stated reason behind almost every compatibility claim in the tradition: 1 Sun, 2 Moon, 3 Jupiter, 4 Rahu, 5 Mercury, 6 Venus, 7 Ketu, 8 Saturn, 9 Mars. One book notes that Western attributions differ for 4 and 7, giving them Uranus and Neptune, but the practitioner sources here use Rahu and Ketu without exception. Each is set out under numbers 1–9.
Friend, neutral and adverse numbers
Each digit is held to have friendly, neutral and adverse counterparts, and this table drives choices of dates, phone numbers, premises and partners. Two features matter. The corpus table is directional, so 2 may treat 6 as adverse while 6 does not return the judgement. And 5 is repeatedly described as having no enemy at all. Individual sources give slightly different lists for the same digit.
Family of numbers
A competing and equally explicit model groups the digits into three families — 1-2-4-7, 3-6-9, and 5-8 — and holds that a number suits every member of its own family. The strongest members are named as 1, then 3 and 6, then 5. This model contradicts the friend-and-adverse table in several specific cells, and the corpus records the contradiction rather than resolving it.
Founder–business fit
Founder–business fit is the question of whether a company's name number supports the person running it. The most mechanical statement here puts the personal name in the same family as the bhagyank and the company name in the same family as the mulank. A competing rule says simply to take a company name to 1, 5 or 6. Both agree the name must not land on a number adverse to the founder.
Timing
Universal year
The universal year, also called the world or global year, is the digits of the calendar year reduced to a single digit, so 2026 reduces to 1. It is described as a background wash that everyone experiences together, with the personal year layered on top of it and outranking it for any individual. One book keeps it as a master value in certain decades rather than reducing it to a single digit.
Personal year
The personal year is the year-long cycle a person is in, and this corpus carries four different formulas for it. The most common one rewrites the date of birth with the year under examination and totals the result. The boundary is disputed too: sources variously begin it on 1 January, on the birthday, around 5 February, or ramp it across a cusp of several months. The cycle runs 1 to 9 and repeats.
Personal month
The personal month is a shorter layer inside the personal year, obtained by adding the month index — January as 1 through December as 12 — to the personal year number. The book that states it most precisely uses the unreduced two-digit personal year rather than the single digit. That same source calls these month vibrations minor, useful for locating events inside a year rather than for setting its direction. The timing dashboard lays them out month by month.
Personal day
The personal day is the thinnest layer in this corpus and the least settled; no source states a formula for it outright. What the sources do supply are two working substitutes: reading the weekday through its ruling planet, and treating the day-of-month number of the calendar date as the day's own number, which is what "lucky date" means throughout the practitioner material.
Launch date selection
Launch date selection is the muhurat-style practice of choosing a date for an act rather than accepting whichever date arrives. The corpus names five anchors to check: the founder's mulank, the mulank and bhagyank together, the business name number, a fixed preferred set of 1-3-5-6 or 3-6-9, and the weekday's planet. The launch date finder ranks the dates in a month against those anchors.
One source that teaches the method also cautions against it becoming a habit: consulting numbers at every moment, it says, is closer to superstition than to the practice.
Date of establishment
The date a business is registered, incorporated or first opened is treated as the company's own date of birth, and both its day number and its full-date total are computed exactly as for a person. This corpus ranks it as the last of the business factors to check, after the name, the brand, the logo and the directors' dates, but it is checked whether the venture is a corner shop or a large group.
Applied areas: name, phone, domain and premises
Mobile number analysis
A mobile number is analysed by dropping the country code, totalling the ten national digits, and keeping both the compound and the reduced digit. This tradition weights the closing four digits far more heavily than the total — one source puts it at roughly ninety-five to five — because the opening digits belong to the operator. Adjacent digit pairs are read individually, and repeated-digit "VIP" numbers are treated as a fault. The phone number analyzer works through both layers.
Domain number
A domain is scored with the same letter table as any other name, after the extension is stripped: only the second-level label is valued, so .com, .co and .in contribute nothing. Digits inside the label do count at face value. One Western source additionally treats the date the domain was bought as the business's own birthday. The domain name analyzer applies the stripping rule before totalling.
Address and premises number
Premises numbers cover house, shop, unit, plot and floor numbers. One book keeps the house number, the street number and the town name as three separate numbers that are never combined, each holding its own relation to the owner. The practitioner sources instead give blanket avoidances, and a technique for shifting a total by writing extra letters or words beside the number when moving is not an option.
Remedies
A remedy in this tradition is an action meant to activate a number a chart lacks. The corpus sorts remedies into behavioural, cosmetic, written, charitable, ritual and structural kinds, and states repeatedly that legitimate ones cost little or nothing. It describes a remedy as a prosthesis rather than a repair, insists effort is still required alongside, and records one source who rejects remedies altogether in favour of knowledge.
Frequently asked questions
What is the difference between mulank and bhagyank?
The mulank comes from the day of the month alone, reduced to a single digit. The bhagyank comes from every digit of the full date of birth, with the year written in four figures. This tradition reads the mulank as temperament and self-image and the bhagyank as life purpose and career ceiling, and holds that the mulank dominates early life before the bhagyank becomes the stronger influence.
Which letter system does business numerology use?
The Chaldean table — values 1 to 8, with no letter carrying 9 — is the default across this corpus and is described as the most widely followed for name work. The Pythagorean table, which uses all nine values, appears as a minority system among the Western sources. The two produce different totals for the same name, so the system in use should always be stated with the result.
Why does the two-digit compound number matter?
Because this tradition holds that the single digit shows what a name appears to be, while the compound behind it shows the hidden layer. A 6 reached through 33 and a 6 reached through 42 are read as different sixes. Practitioners therefore aim at a particular compound rather than at a digit, and check which pair produced the total before judging whether it suits.
Is 13 an unlucky number in this method?
The corpus does not speak with one voice here. Practitioner sources list 13 among the four karmic debt numbers, alongside 14, 16 and 19, and read it as blocked plans and repeated forced change. One classical compound table takes the opposite view, calling 13 a number of change that is not unfortunate as commonly supposed, and a symbol of power when rightly used.
Can a birth number be changed?
No. This tradition holds the mulank, bhagyank and kua fixed at birth and unalterable. Only the name-derived numbers can move, by changing spelling — which is why name correction is the main structural lever in the method. The corpus also states that a corrected spelling does not require changing legal documents, and is activated instead through everyday use.
What does a missing number mean on the grid?
A missing number is a digit with no entry in its grid cell after the birth digits and the auxiliary numbers have been placed. This tradition reads it as a weakened area rather than an absent one, and one book stresses that the quality simply needs developing. Everyone is said to have at least one missing number, and 5 is described as the most commonly absent.
What this glossary does and does not tell you
These definitions describe how a tradition uses its own vocabulary. They are not claims about how the world works, and nothing here is evidence that a number causes a business outcome. Where sources within this tradition disagree — on the master-number set, on the age at which the bhagyank takes over, on when a personal year begins, on whether 13 is a burden or a strength — the disagreement is recorded above rather than smoothed away, because it is real.
A glossary is also not a reading. Knowing that a compound number is the two-digit total before reduction does not tell you which compound suits a particular founder, and the method itself insists that no single number is read in isolation: a name number is judged against the mulank and bhagyank, a date against both of those, an asset number against the union of their adverse lists. Nothing in this vocabulary is financial, legal or medical advice, and none of it is a substitute for research, capital planning or professional counsel.
If you want to see how the terms behave on real inputs rather than in the abstract, the methodology page sets out which rule each calculation follows and where the sources conflict, and the full set of calculators shows the working for every number rather than only the result.
