How to use this calculator
Each pair of Life Path numbers 1–9 has a fixed percentage and note in a built-in table. Master numbers 11, 22 and 33 are looked up as 2, 4 and 6. The table is an arbitrary lookup, not a validated measure.
- 1
Enter both dates of birth. Names are optional and only change the row labels.
- 2
Each date is reduced part by part (day, month, year) to a Life Path number, keeping 11, 22 or 33.
- 3
The pair of numbers is looked up in a table of 45 entries, each with a percentage between 62 and 90, a one-word pairing label and a note. Master numbers are looked up as 2, 4 and 6.
- 4
Read the output as the result of that table, not as a measurement of two people.
Frequently asked questions
How is each Life Path number calculated?
The day, month and year are each reduced on their own, keeping 11, 22 and 33, then added and reduced again. For 1990-06-15 the day 15 becomes 6, the month stays 6 and the year 1990 becomes 1, so 6 + 6 + 1 = 13 reduces to 4. Adding all eight digits in one go gives other results for some dates, for example 1979-12-31 (33 that way, 6 here), which is why a number from another site may not match.
What do the optional name fields do?
Nothing numerical. If filled in, the names replace “Person 1” and “Person 2” in the Life Path row labels. The score, label and note depend only on the two dates, so leaving the names blank changes nothing but the wording.
Where does the percentage come from?
A table with one entry for each pairing of 1 to 9, 45 in total, ranging from 62 (2 with 5, and 4 with 5) to 90 (2 with 6). The order of the dates does not matter because the smaller number is always looked up first.
What is the “Pairing type” word?
A single label attached to each table entry, such as Loving for 2 with 6, Devoted for 4 with 6, Grounded for 3 with 4 or Challenging for 1 with 4, 2 with 5 and 4 with 5. It describes the entry, not the people.
How are 11, 22 and 33 scored?
The result row shows the master number and its title, for example 33 (The Master Teacher), but the lookup uses 2, 4 or 6. A 4 paired with a 33 therefore reads the 4-and-6 entry, which is 86% Devoted.
What do the stars mean?
The percentage divided by 20 and rounded. 62 and 68 show three stars, 78 and 86 show four. Two entries only differing by a few points can show the same star count.
What if both people have the same Life Path?
The doubled entry is used, for example 78% Solid for two 4s, 88% for two 2s and 85% for two 6s. Entering the same date twice produces one of these, not 100%.
Is a love compatibility percentage reliable?
No. Numerology is a belief-based tradition that has not been scientifically validated, and this percentage is a stored figure for a pair of digits. It says nothing reliable about how two people feel or will treat each other, and it should not be a reason to begin or end a relationship.

How to use the love compatibility
Use this love compatibility to numerological love 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 love compatibility calculates your result
The love 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 love 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.
Two dates in, one pair of numbers out
Each date is split into day, month and year, and each part is reduced on its own, keeping 11, 22 and 33. The three results are added and reduced again; 1990-06-15 gives 6 + 6 + 1 = 13, then 4. Some websites add all eight digits in one go instead, which differs for roughly one date in eight, so a number you saw elsewhere may not match. The optional name boxes do not feed the calculation at all; they only swap “Person 1” and “Person 2” for what you typed.
A finely graded table of 45 entries
The tool keeps a score, a one-word label and a sentence for every pairing of 1 to 9. The scores are more finely spread than on the other compatibility pages here: 45 entries share twenty different values between 62 and 90, instead of steps of five. A master number is displayed with its title but looked up as 2, 4 or 6. The percentage is then turned into stars by dividing by 20. The table below picks out the highest and lowest entries to show the range the tool can return.
| Number pair | Score | Label | Note starts |
|---|---|---|---|
| 2 and 6 | 90 | Loving | Two nurturers |
| 2 and 2 | 88 | Mirrored | Deep emotional understanding |
| 3 and 6 | 88 | Warmhearted | Creativity meets nurturing |
| 6 and 9 | 88 | Humanitarian | Both care deeply about others |
| 7 and 8 | 66 | Complex | Spiritual 7 vs material 8 |
| 1 and 4 | 65 | Challenging | Ambition meets structure |
| 2 and 5 | 62 | Challenging | The 5’s need for freedom |
| 4 and 5 | 62 | Challenging | Structure vs freedom |
Worked examples
The runs below used the default dates first, then a pair with names, a third pair of dates and a repeated date. Row three pairs a 4 with a 6, the 6 coming from 1979-12-31. Names only affect the row captions in row two.
| Dates | Life Paths | Score | Label |
|---|---|---|---|
| 1990-06-15 and 1992-03-22 | 4 and 1 | 65% | Challenging |
| 1992-07-29 and 1990-06-15 (Sarah, James) | 3 and 4 | 68% | Grounded |
| 2000-01-01 and 1979-12-31 | 4 and 6 | 86% | Devoted |
| 1990-06-15 twice | 4 and 4 | 78% | Solid |
Labels, stars and the fallback
Labels such as Mirrored, Grounded and Devoted come with each table entry and are not assessments of the people entered. A default entry of 72% labelled “Compatible” exists in the code for pairs outside the table, but every pair of 1 to 9 has an entry and master numbers are mapped to one of them, so ordinary dates cannot reach it.
Treat it as a curiosity
Numerology is a belief-based tradition and has not been scientifically validated. A percentage about love drawn from a lookup table says nothing reliable about two real people and should not decide whether to start, continue or leave a relationship. Both dates must be filled in; if either is blank the tool returns an error row instead.
