Birth Date Compatibility: How Well Do You Two Fit?

Birth date compatibility starts with a simple idea. Your birth date tells us where the Sun, Moon, Venus, Mars and Mercury stood in the sky on the day you arrived. Each of them sat in one of the twelve zodiac signs, and each one says something different about you.

Nebu takes those five placements for both of you and compares them in pairs. The Sun stands for who you are. The Moon is about feelings and comfort. Venus is what you love and how you flirt. Mars is drive and desire. Mercury is how you think and talk.

The comparison is not a score from a lottery machine. It looks at how two signs relate to each other: same sign, easy partners, opposites, signs that rub against each other, or neighbours that speak different languages. Each relationship type has its own flavour, and Nebu describes it in plain words.

The first area is the core: Sun and Sun. It shows who you are as a pair and how your basic natures meet. The second is the heart: Moon and Moon. This is the quiet layer, where you learn how each of you feels safe, and what a cosy evening looks like.

The third area is attraction. Here the Venus of one person meets the Mars of the other, and the result is chemistry, or the lack of it. The fourth is talk: Mercury and Mercury. It shows how you chat, how you argue and, maybe most important, how you make up.

The fifth area is everyday life. The Sun of one meets the Moon of the other, and that tells you a lot about sharing a home, a calendar and a fridge. Together the five areas give you a rounded picture, not a single number to stress about.

Start with the overall verdict, then go area by area. A high score does not mean a perfect couple, and a low one does not mean doom. It tells you where things come easily and where you will need to put in a bit of work.

Friction is the part people fear most, but it is also where couples grow. Two signs that clash are often two people who push each other to stop being lazy about something. Treat a tense area as a task, not a verdict.

Try this: read the result together, and let each person pick the area that felt most true. Then pick the one that felt wrong. The second conversation is usually the more interesting one.

The Moon moves fast. It changes sign roughly every two and a half days, and on the day it switches, the exact time of birth decides which sign it was in. Without a birth time, the Moon sign for that day can be one sign off.

Nebu lets you know when this could apply to your dates. If your Moon result feels odd, check the neighbouring sign too. The other three personal planets move more slowly, so Sun, Venus, Mars and Mercury are far more reliable from the date alone.

Astrological compatibility is a tradition that goes back thousands of years. It is a lovely way to talk about relationships, but it is not science and it cannot predict whether two people will stay together. Real couples are shaped by habits, values, timing and effort.

Use the result the way you would use a good magazine column. Enjoy it, argue with it, laugh at it, and take away the bit that makes you want to ask your partner a better question. The decisions stay with you two.
