Compatibility
Seven ways to calculate compatibility: by zodiac sign, by birth date, by name, by Destiny Matrix, by biorhythms, by Chinese zodiac and by full BaZi charts. Plus 156 pages of ready-made profiles — every pair of zodiac signs and every pair of Chinese zodiac animals.
Where to start
If you want everything at once — couple compatibility by every method: enter the details of both people once, and the site calculates compatibility by zodiac signs, the Chinese zodiac, the Destiny Matrix, BaZi, Kundali Milan, numbers, names and biorhythms, and AI explains each result. There you can also compare yourself with several people without entering your own details again.
If you only know the signs, use zodiac compatibility: pick two signs and get a score and a profile of the pair.
If you have full birth dates, use by birth date (numerology) and by Chinese zodiac: the latter takes the year boundary from Lichun rather than January 1, so it sometimes gives an unexpected sign.
If you want a quick answer about what you argue about most, use by name.
If you know both people's birth dates, times and places, try BaZi compatibility: it compares the full charts, not just the year signs. The Korean version of the same comparison is gunghap.
If both birth times are known precisely, you can also compare the charts by Zi Wei Dou Shu: what kind of spouse each chart expects and who each person turns out to be in the other's chart.
Methods in this section
| Method | What you need | What it calculates |
|---|---|---|
| By Zodiac Sign | two signs | the angle between the signs on the zodiac wheel |
| By Birth Date | two dates | the Life Path Numbers and the difference between them |
| By Name | two names | the name numbers and the couple's number |
| By Destiny Matrix | two dates | the central arcana and the couple's arcana |
| By Biorhythms | two dates | the phase difference of the three cycles |
| By Chinese Zodiac | two dates | the triangles of compatibility and the clashes |
| By Human Design | two dates, times and places of birth | the channels between the charts and the center formula |
| By Zi Wei Dou Shu | two dates, times and places of birth | the Spouse and Life palaces, the Four Transformations and the love stars in each other's charts |
All calculations run in your browser: dates and names are not sent anywhere.
Ready-made pair profiles
78 zodiac sign pairs — from Aries and Aries to Pisces and Pisces. Pairs aren't duplicated: "Aries and Taurus" and "Taurus and Aries" share one page.
78 Chinese zodiac pairs — every combination of the twelve animals, analyzed according to the traditional rules of triangles and clashes.
Why 78 and not 144: the number of combinations of 12 signs taken 2 at a time with repetition is exactly 78. Treating "Aries and Taurus" and "Taurus and Aries" as separate pages would mean creating duplicates, and search engines don't like that.
What you need for the calculation
A zodiac sign or a birth date, depending on the method. No birth time, city or registration needed.
For name-based methods, enter the name the person actually goes by in everyday life: the full name on their passport gives a different number, and schools interpret that difference as the gap between how a person is seen and how they feel about themselves.
Frequently asked questions
Which method is the most accurate?
None. Compatibility by signs, numbers and biorhythms has no proven link to how relationships actually turn out: studies of astrological compatibility, including a comparison of the birth dates of tens of thousands of married couples, found no systematic effect.
Why do you show 40% when another site shows 90%?
Because the scale is invented by whoever runs the site. There is no single compatibility table — there are dozens, and they disagree. We explain our logic right on the calculation pages so you can see where the number comes from.
What should I do with a low result?
Nothing. The number in a calculator is not a fact about your relationship. It's more useful to read the "weak spots of the pair" section: it describes typical differences in character, and those really are something you can work on.
Can I check compatibility with someone who doesn't know about it?
Technically, nothing stops you. Just keep in mind that you'll be interpreting the result through your own expectations, not theirs.
