# Love Calculator by Date of Birth A love calculator by date of birth compares two people's numerology numbers: each mulank and bhagyank, and each name number if you add names. Every pair is read through the graha friendship table, and this numerology compatibility calculator turns those relations into a score out of 100, showing exactly which relation earned which points. ## How does a love calculator by date of birth and name work? It works out three numbers for each person and compares them in pairs. The mulank is the day of birth reduced to one digit, so someone born on the 19th has 1+9 = 10, then 1+0 = 1. The bhagyank is every digit of the full date added and reduced. With names, the name number adds the Chaldean value of every letter. Each number is ruled by a graha in ank jyotish (1 Sun, 2 Moon, 3 Jupiter, 4 Rahu, 5 Mercury, 6 Venus, 7 Ketu, 8 Saturn, 9 Mars), and each pair is read through the natural friendship of its two rulers. The calculator prints every step, so the whole reading can be checked by hand. ## What is numerology compatibility? Numerology compatibility is the practice of reading two people's numbers against each other, on the idea that numbers ruled by friendly grahas describe temperaments that sit easily together. The numbers themselves come from two traditions. The mapping of 1 to 9 onto the nine grahas and their friendships is Indian, from ank jyotish, and the letter values used for names are Chaldean, a Western esoteric system named for Babylon. Applying either to a couple is a modern application: no classical text matches two people by their birth-day number. A numerology love calculator describes temperament in the tradition's terms. It is not a forecast of how a relationship goes. ## How is birth date numerology compatibility calculated? Take each date of birth, reduce the day to get the mulank and the whole date to get the bhagyank, then compare like with like. A pair of numbers earns the Graha Maitri points of its two ruling grahas, the same points kundali matching uses: 5 when the rulers are friends both ways or the numbers are the same, 4 for friend and neutral, 3 for neutral both ways, 1 for friend and enemy, 0.5 for neutral and enemy, 0 for enemies both ways. Here, each pair's points are multiplied by its weight and divided by 5. With dates alone, mulank and bhagyank weigh 50 each; with both names they weigh 40 each and the name numbers 20. The total is the score. ## How do I read the numerology compatibility chart? Find the first person's number, then read across to the second. The chart on this page gives every pair from 1 and 1 to 9 and 9 a word and a number: friendly for 4 or 5 Graha Maitri points, neutral for 3, contrary for 1 or less. The same number twice counts as full agreement. The chart is symmetric, so 7 and 3 read exactly as 3 and 7. Use it for any of the numbers: two mulanks, two bhagyanks, or two name numbers. Rahu and Ketu, which rule 4 and 7, are absent from the classical friendship table, so their rows follow the modern convention, and the chart flags that. ## Which numerology compatibility numbers are considered friendly? By the friendship table, 1, 2, 3 and 9 form one friendly group, ruled by the Sun, Moon, Jupiter and Mars, and 4, 5, 6 and 8 form another, ruled by Rahu, Mercury, Venus and Saturn. 7, ruled by Ketu, reads as friendly with 6, 8 and 9. Pairs across the two groups tend to read neutral or contrary: 3 and 6, for example, score 0.5 of 5 because Jupiter and Venus are not friends. None of this makes one number better than another. Each digit carries a character, and the pairing describes how the tradition sees two characters together, nothing more. There is no evidence that matching numbers changes how a relationship goes. ## What is the numerology compatibility of 1 and 9? Friendly, and fully so: 1 is ruled by the Sun and 9 by Mars, and each counts the other a friend, which earns 5 of 5 Graha Maitri points. The tradition reads the pair as two assertive numbers that respect each other, with the caution that both like to lead. The other pairs people ask about read differently. 3 and 4, 7 and 3 and 4 and 7 are neutral at 3 points; 4 and 6 is friendly at 5, because Rahu and Venus are counted friends; and 3 and 6 is contrary at 0.5. Each has a card above the chart with its reasoning. ## Can numerology compatibility decide a marriage? No, and no honest reading of the tradition says it can. Numerology compatibility for marriage reads three numbers per person against a table of planetary friendships; it knows nothing about either person beyond their date of birth and their name. The classical Vedic way to match a couple is Kundli Milan, the ashtakoota system, which compares the two Moons by nakshatra and sign across eight kootas worth 36 points, and which needs birth times and places. Graha Maitri, the friendship score this page borrows, is one of those eight kootas. Use this calculator as a reading of numbers, and the matching report for the traditional match. ## Is numerology compatibility by name different from by date of birth? Yes. Numerology compatibility by date of birth uses the mulank and bhagyank, which are fixed at birth and cannot change. Numerology compatibility by name uses the Chaldean total of the name each person goes by, which does change: a married surname, a nickname or a new spelling gives a different number. That is why this calculator weighs the name numbers at 20 of 100 and the birth-date numbers at 40 each, and why it compares names only when both are given. The Chaldean letter values are a Western esoteric system, named for Babylon, and are not part of ank jyotish. Try the names you actually use, and compare. ## Frequently asked questions ### How accurate is a love calculator by date of birth? The arithmetic is exact and every step is printed, so the numbers can be checked by hand. What the numbers mean is a different question. The reading reports how a table of planetary friendships sees two sets of numbers, and there is no evidence that such a table predicts how two people get on. Treat the score as a description in the tradition's terms, not a measurement of a relationship. ### Can I use this numerology compatibility calculator for marriage? You can read two people's numbers with it, and many people do before a marriage. As a marriage numerology compatibility calculator it compares mulank, bhagyank and name numbers only. The traditional Vedic match for marriage is Kundli Milan, which uses both birth charts, scores eight kootas out of 36 and checks for Mangal dosha. Numerology is a modern addition to that, not a replacement for it. ### Does a love calculator by date of birth and time for marriage use the time? Numerology uses the date only, so birth time changes nothing on this page. Two people born on the same day have the same mulank and bhagyank whatever the hour. Birth time matters in the horoscope match, where it fixes the Moon's nakshatra and the ascendant. For a match that uses time and place, Kundli Milan is the calculator to use. ### What is numerology compatibility by name? Numerology compatibility by name adds the Chaldean value of every letter in each person's name, reduces each total to one digit, and reads the two digits through their ruling grahas. Enter both names to include it; the name pair then carries 20 of the 100 points. The Chaldean values are a Western esoteric system, not Indian, and a different spelling gives a different number. ### Which name should I use for birthdate and name numerology compatibility? Use the name each person actually goes by in daily life, as they spell it today. Practitioners differ on whether to use the full birth name, and a married surname or a nickname changes the total, so the honest approach is to try both and read them as two different names. The birth-date numbers stay the same either way and carry 80 of the 100 points. ### Are 1 and 9 compatible in numerology? Yes, by the friendship table 1 and 9 is one of the most harmonious pairings. The Sun rules 1 and Mars rules 9, and each counts the other a friend, which earns the full 5 of 5 Graha Maitri points. The tradition reads two assertive numbers that respect each other, with the caution that both prefer to lead. A reading of numbers, not a forecast. ### Are 3 and 6 compatible in numerology? By the friendship table, 3 and 6 is a contrary pairing, scoring 0.5 of 5. Jupiter rules 3 and Venus rules 6; Jupiter counts Venus an enemy and Venus counts Jupiter neutral. The tradition reads two teachers with different lessons: counsel against comfort. Contrary is a description of friction in the tradition's terms, not a judgement on two people. ### Is love numerology compatibility the same as Kundli Milan? No. Kundli Milan is the classical Vedic match: it compares the two Moons by nakshatra and sign across eight kootas and needs birth times and places. Love numerology compatibility compares numbers derived from dates and names. The two share one piece, the natural friendship of the grahas, which Kundli Milan scores as Graha Maitri and this page borrows for its points. --- Source: https://vedicsense.in/love-calculator-by-date-of-birth Method: nirayana (sidereal) rashis, Lahiri ayanamsha, whole-sign bhavas, planetary positions to arc-second accuracy.
