This page compares four numbers, not two. Each person contributes a Mulank, the digit sum of the day of the month they were born on, and a Bhagyank, the digit sum of their entire date of birth. Both reduce to a root between 1 and 9, and every root sits on a graha: 1 Sun, 2 Moon, 3 Jupiter, 4 Rahu, 5 Mercury, 6 Venus, 7 Ketu, 8 Saturn, 9 Mars. The check then asks how those grahas stand with one another and answers friendly, neutral or challenging, with the reason shown. That is the whole method, and it needs no birth time or birth place.
This is the lighter, faster check, not real Vedic matching, and we would rather say so on the way in than on the way out. Two calendar dates cannot tell you where the Moon stood, which nakshatra it fell in, what condition the seventh house is in, or whether either chart carries Mangal Dosha. If your question is about marriage, run kundli matching instead. That tool compares both birth charts across the eight Ashtakoot kutas out of 36 points and flags Nadi and Bhakoot Dosha. Treat this page as a five-second orientation, and the chart comparison as the reading.
Most numerology compatibility charts online are copied from each other and disagree in places. This one is read off the classical Parashari natural-friendship table that this site's own chart engine already uses, so the numerology page and the kundli cannot contradict each other. Rahu and Ketu are chhaya grahas and are simply absent from that table, so the standing convention applies: 4 reads with Saturn's relations and 7 reads with Mars's. Here is the entire result, every number against every other.
| Number | Graha | Friendly with | Neutral with | Challenging with |
|---|---|---|---|---|
| 1 | Sun | 1, 2, 3, 5, 7, 9 | none | 4, 6, 8 |
| 2 | Moon | 1, 2, 3, 7, 9 | 5 | 4, 6, 8 |
| 3 | Jupiter | 1, 2, 3, 7, 9 | 4, 8 | 5, 6 |
| 4 | Rahu | 4, 5, 6, 8 | 3, 7 | 1, 2, 9 |
| 5 | Mercury | 1, 4, 5, 6, 8 | 2 | 3, 7, 9 |
| 6 | Venus | 4, 5, 6, 8 | 7, 9 | 1, 2, 3 |
| 7 | Ketu | 1, 2, 3, 7, 9 | 4, 6 | 5, 8 |
| 8 | Saturn | 4, 5, 6, 8 | 3 | 1, 2, 7, 9 |
| 9 | Mars | 1, 2, 3, 7, 9 | 6 | 4, 5, 8 |
Three things are worth noticing. The reading is symmetric, so it makes no difference which of you is entered first. Every number is friendly with itself, because a graha is at home in its own company, which is why two people born on the same day of the month always share a friendly Mulank pair. And 4 and 8 are friendly with each other, as are 7 and 9, because each pair lands on one graha: Saturn in the first case, Mars in the second.
Counted across all 36 distinct pairs of different numbers, 17 read friendly, 6 read neutral and 13 read challenging. A challenging pair is therefore not a rare misfortune, but roughly one pairing in three.
Take two readers. The first, born on 29 May 1990. The second, born on 8 August 1988.
Now read the pairs off the table. Mulank 2 against Mulank 8 is Moon against Saturn, and Saturn counts the Moon an enemy, so that pair comes back challenging. Bhagyank 8 against Bhagyank 6 is Saturn against Venus, who are mutual friends in the classical table, so that pair is friendly. Crossing over, the second person's Mulank of 8 meets the first person's Bhagyank of 8, the same number, which is friendly. That is a genuinely mixed picture, and mixed is the ordinary result.
A challenging pair is a description of temperament, not a verdict on a relationship. The tradition is saying that two grahas want different things at different speeds. Moon and Saturn is the classic case: one number reads by feeling and wants the thing settled tonight, the other reads by structure and wants to sleep on it. Nothing in that says the relationship will not work.
Treat a challenging result the way a practitioner would, as a note about where the two of you will need to translate for each other. It is not a warning, it is not a prediction, and it carries no timing. Anyone telling you a number pair means a marriage will fail is selling something. Read a friendly result with the same restraint: it says the two temperaments run in step, not that the relationship needs no work.
Six pairs come back neutral, and neutral here means the classical table genuinely has nothing to say rather than that we averaged something out. 3 and 8, Jupiter and Saturn, appear in neither each other's friend list nor each other's enemy list. 2 and 5 is more interesting: the Moon counts Mercury a friend, but Mercury counts the Moon an enemy. The table is asymmetric there, classically so, and the two directions cancel to neutral. 4 and 7 is a special case. Those are Rahu and Ketu, the two ends of one axis and always exactly opposite, and the Parashari table never ranked them, so reporting anything else would be an invention. The remaining neutral pairs are 3 and 4, 6 and 7, and 6 and 9.
Because no honest arithmetic turns a three-valued classical friendship table into a number out of 100. Any site showing you 83 percent compatibility has picked weights out of the air and dressed them up as precision. We return friendly, neutral or challenging, name the grahas that produced it, and stop there. The one real score near this subject is the Ashtakoot total out of 36, a classical system with defined maximum points per kuta, and that lives on the kundli matching page where it belongs.
If you want to go further than two dates, the full numerology calculator gives each of you your Namank and Lo Shu grid as well, the numerology hub lists the rest of the free tools, and the marriage report works from both actual birth charts, with real planetary positions, house analysis and Vimshottari dasha timing behind it.
Each person's Mulank is the digit sum of their day of birth and their Bhagyank is the digit sum of their full date of birth, both reduced to a root between 1 and 9. Each root maps to a graha, and the two grahas are looked up in the classical Parashari natural-friendship table. The result is reported as friendly, neutral or challenging, with the grahas that produced it named. No birth time or birth place is used at any point.
No, and it is much lighter. Numerology compatibility uses two calendar dates and compares four numbers. Kundli matching compares both full birth charts across the eight Ashtakoot kutas out of 36 points, checks Nadi and Bhakoot Dosha, and needs each person's birth date, time and place. For a marriage question the chart comparison carries far more weight than a number pair does.
It means the grahas behind the two numbers are natural enemies in the classical table, so the tradition reads the pairing as having friction built into its temperament. It is not a prediction and it carries no timing. Across the 36 distinct pairs of different numbers, 13 read challenging, so this is a common result rather than a rare one, and most couples find at least one challenging pair among their four numbers.
Because the classical friendship table is three-valued, and no defensible arithmetic converts it into a number out of 100. A site that shows a percentage has chosen weights arbitrarily and presented them as precision. We return friendly, neutral or challenging and name the grahas behind the verdict, so you can check the reasoning yourself.
No. Both numbers come from the calendar date alone, so a date of birth for each person is enough. Birth time and birth place are needed for a kundli, where the ascendant and the house positions shift every few minutes, but they play no part in Mulank or Bhagyank. That is what makes this the lowest-friction check on the site.
Same numbers always read friendly, because both sit on the same graha and a graha is at home in its own company. Two people born on the same day of any month therefore share a Mulank and an automatically friendly pair. The tradition reads such a pairing as easy to understand each other in, since both temperaments run to the same rhythm, though it says nothing about the other three numbers in the comparison.
The tradition does not rank the nine numbers for marriage, and neither do we. What the table describes is how any two numbers sit with each other, not whether one number is a better partner in general. Number 1 happens to have the widest friendly set and no neutral pairings at all, but that is a feature of the friendship table rather than advice about whom to marry.
A full chart-based reading goes well beyond two calendar dates, since it works from both people's actual planetary positions, the houses those grahas occupy, and the Vimshottari dasha each of you is running now.
