How to use this calculator
- 1
Enter both dates of birth. Both are required.
- 2
Each date is reduced in three parts (day, month, year) and the three results are added and reduced again to give a Life Path number, with 11, 22 and 33 kept at each step.
- 3
The two Life Path numbers are looked up in a table of 45 pairings, each with a score from 60 to 95 and a sentence of analysis.
- 4
The tip line depends only on the score: 85 and above, 70 to 84, or below 70.
Frequently asked questions
How is the Life Path number worked out here?
The day, the month and the year digits are each reduced on their own, and master numbers are kept. The three results are added and reduced once more. For 1990-06-15: day 15 becomes 6, month 6 stays 6, the year 1+9+9+0 = 19 becomes 1, and 6+6+1 = 13 reduces to 4.
Why do I get a different Life Path number on another page?
Some tools add every digit of the full date at once, which can end on a different number. For 1979-12-31 this page gives 6, while an all-digits sum gives 33. The two routes are both common, and neither is a measured quantity.
How are the 45 scores spread?
From 60 to 95 in steps of five: 15 pairings score 85 or more, 24 score between 70 and 84 and 6 score below 70. The top entry is 2 with 6 at 95, and the lowest are 2 with 5 and 4 with 5 at 60.
What does the Tip line mean?
It is chosen only by the score. 85 and above reads “Highly compatible — natural harmony exists between you”, 70 to 84 reads “Good compatibility — requires understanding and communication”, and anything lower reads “Challenging but possible — differences can be growth opportunities”.
What happens with master numbers?
Your Life Path is shown as 11, 22 or 33 when that is what the reduction gives, but the score lookup reads them as 2, 4 and 6. A person with 11 and a person with 4 are scored as the 2-and-4 pairing, which is 75%.
Does it matter which date goes in which box?
No. The boxes are labelled “Your date of birth” and “Partner’s date of birth”, but the lookup puts the smaller number first, so swapping them returns the same score and analysis.
What if both dates are identical?
The same-number pairing is used. Two 9s score 85% and two 4s would score 75%. A date entered twice does not return 100%, because no entry in the table exceeds 95.
Can the score tell me whether a relationship will work?
No. Numerology is a belief-based tradition that has not been scientifically validated, and the percentage is a table entry for two numbers. It says nothing reliable about a real relationship and should not be used to decide anything about one.

How to use the numerology compatibility
Use this numerology compatibility to he numerological compatibility between two people using their life path numbers. Enter your name or date of birth above and the result appears instantly. No registration needed.
How the numerology compatibility calculates your result
The numerology compatibility uses the Pythagorean system — the most widely used numerology method in the West. Letters are assigned values A=1 through I=9, then cycling back. Numbers are summed and reduced to a single digit (or master numbers 11, 22, 33). This gives a stable, repeatable result tied to your birth data or name.
How to interpret your result
Numerology is a self-discovery system, not a prediction method. Think of the numerology compatibility as a mirror — it reflects patterns and tendencies that may resonate with your experience. Many people use it alongside astrology, personality tests, and journalling as part of a broader self-awareness practice. Results are instant and free.
Life Path from three separate parts
This calculator reduces the day, the month and the year individually before combining them. The day and month are reduced on their own, the four year digits are added and reduced, and master numbers 11, 22 and 33 are preserved at each stage. The three results are then added and reduced a final time. For 1990-06-15, day 15 gives 6, month 6 stays 6, the year 1+9+9+0 = 19 gives 1, and 6+6+1 = 13 gives 4. A birth on the 29th feeds the master number 11 into the sum, which an all-digits method would not do, so some dates get a different Life Path here than they do on pages that add every digit at once.
How the 45-pair table works
The two Life Paths are looked up in a fixed table with one entry per pairing of 1 to 9, each holding a score and a sentence of analysis. Scores run from 60 to 95 in steps of five. Master numbers are read as 2, 4 and 6 for the lookup, so an 11 with a 4 uses the 2-and-4 row. A tip is then added according to the score, using the bands in the table below. Since 65 and 60 fall below the 70 mark, a few pairings, such as 1 with 4 or 4 with 5, are always described as challenging, whatever the two people are actually like.
| Score | Tip line starts | Pairings in table |
|---|---|---|
| 85–95 | Highly compatible | 15 |
| 70–84 | Good compatibility | 24 |
| 60–65 | Challenging but possible | 6 |
Worked examples
Five fixed-date runs follow. Row one is a 4 with a 1, which falls in the lowest band, row two is a doubled 9, and row three is a 4 with an 8. Row four contains a master number 11 that is looked up as a 2 (so the 2-and-4 sentence appears), and row five shows how a 1979 date comes out as 6 on this page.
| Dates | Life Paths | Score | Analysis line |
|---|---|---|---|
| 1990-06-15 and 1992-03-22 | 4 and 1 | 65% | Different pace — 1 wants speed, 4 wants stability. Requires patience. |
| 1985-03-10 twice | 9 and 9 | 85% | Idealistic, humanitarian, and compassionate — great shared mission. |
| 1984-02-11 and 1990-06-15 | 8 and 4 | 90% | Power combination — hardworking, disciplined, and materially successful. |
| 1984-01-06 and 1990-06-15 | 11 and 4 | 75% | Stable and reliable — 4’s practicality grounds 2’s emotions. |
| 1979-12-31 and 1990-06-15 | 6 and 4 | 85% | Excellent — 4’s reliability and 6’s nurturing create a perfect home. |
Why another page shows a different percentage
There is no single standard table behind these scores. The pairing of 4 with 6 reads 85% on this page, 80% on the birth date compatibility page and 86% on the love compatibility page, because each page holds its own hard-coded list. Comparing a percentage across pages therefore tells you about the tables, not about the people entered.
What to keep in mind
Numerology is a traditional, belief-based practice and has not been scientifically validated. The star rating and the sentence of analysis come from a table, and they say nothing reliable about a real relationship, friendship or working partnership, so they should not influence real decisions. If either date is missing, the tool simply asks for both dates.
