Not a match score. What a comparison shows is where two people reinforce each other, and where both of them need room.

BaZi compatibility is a way of placing two birth charts next to each other, yours and someone else's, to see how the two patterns interact: which parts fill each other in, which parts drain each other, and what each person actually needs from a relationship. The result is not a number. It is a picture of the dynamic.

The question people type is usually a short version of one thing: are we compatible. BaZi answers it differently from what most people expect. It does not hand down a verdict of compatible or incompatible, because no two charts are identical and no two charts are opposite in every way. What it gives you is a map of the dynamic: the places where the two of you move easily together, the places where you test each other's patience, and what needs to be said out loud so the second kind of place does not pile up.
That is why a comparison is most useful for people who are already together rather than as a filter for candidates. It explains the friction you have already felt but could not name, and it shows that the friction is usually not about who is wrong. It is about two rhythms running at different speeds.
Each birth chart is calculated from one person's date, time, and city of birth, then summarised as a balance of five natural forces: Wood, Fire, Earth, Metal, and Water. When two charts are placed next to each other, four things are read.
Rina was born with strong Fire. She decides quickly, likes to keep moving, and comes alive when something new is on the table. Bayu was born with strong Earth. He weighs things for a long time, builds slowly, and feels safest when everything is settled.
Compared, their charts show two things at once. First, the strength: Rina's energy moves Bayu out of his comfort zone, and Bayu's steadiness turns Rina's ideas into finished things instead of plans. Second, the friction point: Rina reads Bayu's caution as a lack of support, while Bayu reads Rina's speed as a disregard for risk. Both are misreading the same thing, which is how each of them keeps themselves safe.
What changed after they saw the comparison was not the feeling. It was the sentence. Rina stopped saying "you always slow me down" and started saying "I need you with me for the first two weeks". That is a realistic outcome from a compatibility reading.
The Compatibility tool on UnlockMyBazi compares two charts for free, with no account. All it needs is a name, a birth date, and, if you know them, the birth time and city for both people. The result appears immediately on the same page.
The calculation uses astronomical solar term tables and a true solar time correction based on the city of birth, so the figures are fixed and do not change between visits. If you then want a much deeper written reading for your own chart, see the options on the home page.

This part is written plainly on purpose. Comparing two charts does not guarantee that a relationship will work or fail, does not set a wedding date, and does not give anyone permission or a prohibition. A pattern is not a fate. It only shows the direction things usually take when nobody is paying attention.
Two people with many friction points can last for decades because both of them learned how to talk. Two people whose charts look smooth can end it because nobody tended to it. What decides the outcome is everyday behaviour, and that sits outside the reach of any chart.
A healthy way to use the result: read it as material for a conversation with your partner, not as a judgement of them. One question is almost always worth asking afterwards: "which part of this do you recognise too?"
In the classical literature this comparison is done by reading the relationship between each person's Day Master together with the interaction of the stems and branches across their four birth pillars. Those terms are written here once so that you recognise them if you meet them elsewhere. Everywhere else on UnlockMyBazi the same content is translated into everyday language: self element, abundant forces, thin forces, and timing. You do not need to memorise a single term to use the result.
No. A comparison reads the pattern of a relationship, not events on a calendar. It shows how each person tends to give, what each one needs in order to feel safe, and where the two patterns pull in different directions. Whether a relationship lasts is decided by what both people do with that information.
Year based matching hands the same answer to everyone born in the same year, which means tens of millions of people read an identical result. A BaZi comparison uses the full birth date and, when it is known, the birth time, so two people born in the same year can come out very differently.
No. The comparison runs on birth dates alone and still shows the main direction of the relationship. Birth time adds one more layer, mostly the part about home life and long term plans, so the result is sharper when both times are known. A missing time is left blank rather than guessed.
Not by itself, and sameness is not a problem either. Two people with the same self element often understand each other quickly, but they also tend to run out of energy over the same things at the same time. A useful comparison reads both charts as a whole instead of one shared detail.
