Numerology can read two people's compatibility straight from their dates of birth. This calculator reduces each date to its Life Path number, looks up the planet ruling each, and reads the pair against the number-friendship grid to return one of four ratings. Mulank, the number taken from the day of birth alone, is a different figure and is explained below.
The percentage is this app's own: the bands 88 / 82 / 72 / 55 are cut-points no source supplies. The number-friendship grid behind this verdict has no located source - not classical, not Cheiro. It is not the planetary friendship of BPHS ch. 3 either: the two tables disagree. It is common modern practice, shown with that stated. Numerology and Vedic astrology are separate systems. Nothing on this page is computed from your chart, and no number here is averaged with a chart result.
Numerology turns a date of birth into two key numbers. Your Mulank (root or psychic number) is the single-digit total of the day you were born - someone born on the 23rd has a Mulank of 5 (2+3). Your life-path or Bhagyank (destiny number) is the single-digit total of the whole date of birth.
Each number from 1 to 9 is ruled by a planet, so comparing two people means comparing the friendship between their ruling planets.
The Mulank reflects day-to-day temperament, while the life-path number points to the longer direction of life. Compatibility is strongest when both partners' numbers are ruled by friendly planets, and mixed friend-and-enemy links show exactly where a couple needs to make an effort.
Which of the two the score is built on matters, and it is the Life Path. Mulank is set out here because it is the number most readers arrive looking for, and because a couple reading their own charts will want both; but the rating this page returns compares Life Path numbers only. The Mulank calculator computes that number on its own page.
The rating compares the two Life Path numbers. A Life Path here is the reduced birth month plus the reduced birth day plus the reduced digit sum of the birth year, reduced once more with 11, 22 and 33 left standing. For 23 May 1990 that is month 5, day 2+3 = 5, and year 1+9+9+0 = 19 = 10 = 1, giving 5 + 5 + 1 = 11, which is kept as the master number 11.
The two Life Paths are then reduced to single digits before the grid is consulted, so a master 11 is compared as a 2, and the pair is mapped onto four fixed bands: 88 if the roots are equal, 82 if each lists the other as friendly, 72 if only one does, and 55 if neither does. Those cut-points are this app's own and no source supplies them, which the tool states beside the result rather than leaving to be assumed.
Your Mulank (root or psychic number) is the single-digit total of your day of birth - for example, someone born on the 23rd has a Mulank of 5 (2+3). It reflects your core nature and is one of the main numbers used for compatibility.
Numbers whose ruling planets are friends blend best - 1, 2, 3 and 9 (Sun, Moon, Jupiter, Mars) support one another, while enemy pairs like 1 and 8 or 5 and 9 can create friction. The calculator reads the two Life Path numbers against that friendship grid.
No. Birth-date numerology gives a quick read on temperament and harmony, but a full Vedic match uses Ashtakoot Guna Milan from both birth charts. Treat this as a starting point, not a final verdict.
The Life Path number. Each date is reduced to reduced-month plus reduced-day plus reduced-year-digit-sum, the two results are reduced to single digits, and those are compared through the number-friendship grid. Mulank, which comes from the day of birth alone, is a different number and does not enter this score; it is computed on its own page.
Because the result comes from four fixed bands rather than a continuous scale: 88, 82, 72 or 55. Any two pairs whose Life Path roots stand in the same relation return the same figure. The bands are this app's own cut-points and are not supplied by any source, so the number is a label for one of four cases rather than a measurement.
