Love compatibility by birth date
Are you compatible? Check by birth date
Not just your signs: your whole charts
Two birth dates, two full charts. NEBO checks where your Venus, Mars, Moon and Sun meet, and gives you the chemistry, the red flags and how each of you loves. Then a pair score from five systems, not one.
Sign-only compatibility is a rough guess: two Leos can be a dream or a disaster. Birth dates show the actual planets.
How NEBO checks two birth dates
Five planets and the Ascendant of one chart against the same points of the other. Every close aspect counts, with its own weight.
| Contact | Weight |
|---|---|
| Mars and Venus | 2.2 |
| Moon and Sun | 1.6 |
| Moon and Venus | 1.4 |
| Sun and Venus | 1.2 |
| Ascendant and Venus | 1.2 |
| Moon and Moon | 1.1 |
| Venus and Venus | 1 |
| Ascendant and Mars | 1 |
| Mars and Sun | 0.9 |
| Mars and Mars | 0.8 |
| Mars and Moon | 0.8 |
Trines and sextiles add calm, squares and oppositions add heat, a conjunction adds both. Heat counts at 80%: sparks matter, but they don't hold a couple together alone. Without a birth time NEBO skips the Ascendant, and the Moon if it changed sign that day.
One pair score, five systems
The love chemistry is the biggest part. The rest checks what it misses.
75% and up is a strong pair, 62% a good one, 48% a working one, below that a hard one. NEBO also flags rare links that turn up in fewer than 15% of pairs, like Venus on Mars or Sun on Moon.
Celebrity couples
Love chemistry for couples the app already knows, by the same formula it uses for you.
79%Rihanna + A$AP Rocky
Love chemistry 79%. Strongest link: Mars in harmony with Venus, Moon opposite Sun.

How you love, by Venus sign
Your Venus sign is often not your Sun sign. NEBO finds it from your birth date.
| Venus in | How you love | How you show it |
|---|---|---|
| ♈︎ Aries | You fall in love in a second and go straight on the offensive. You like to conquer, not to wait to be noticed. | Through actions and surprises: a spontaneous trip, a gift for no reason, “let’s go right now” |
| ♉︎ Taurus | You fall in love slowly, through the body and sensation: first it has to feel calm and pleasant, everything else comes after. | Through care for comfort: good food, touch, nice things, stability |
| ♊︎ Gemini | You fall for a mind: if you can talk to someone till morning, you’re already gone. | With words and messages: memes at 3 a.m., long talks, shared plans |
| ♋︎ Cancer | You fall in love deeply and carefully. First you check it’s safe, then you get attached seriously and for a long time. | With care: feeding them, tucking them in, remembering every little thing |
| ♌︎ Leo | You love brightly and theatrically. Love is a celebration for you, and you want it admired. | Generously and beautifully: big gestures, compliments, attention the whole room can see |
| ♍︎ Virgo | You fall in love quietly and watchfully. You assess for a long time, but once you choose, you’re the most attentive partner in the world. | With practical help: fixing, reminding, sorting out daily life |
| ♎︎ Libra | Love for you means a couple, a partnership, “us”. You’re made for relationships and don’t handle being alone well. | With attention, aesthetics and compromise: beautiful dates, a willingness to meet halfway |
| ♏︎ Scorpio | You love with your whole being or not at all. You need total closeness - body, soul and secrets. | With devotion: you’d tear anyone apart for your person |
| ♐︎ Sagittarius | You fall for an adventure. You need someone you can grow, travel and laugh with. | With shared adventures, honesty and generosity |
| ♑︎ Capricorn | You love seriously and responsibly. You don’t waste yourself on flings - you need something that will last for years. | With reliability: plans for the future, support through action, stability |
| ♒︎ Aquarius | You fall for the unusual. First you’re friends, then suddenly more - and keeping your freedom matters to you even in a couple. | With friendship and respect for freedom: you don’t get jealous or smother |
| ♓︎ Pisces | You love like it’s a movie: you dissolve into the person, idealize them and give yourself completely. | With tenderness, self-sacrifice and romance: poems, music, quiet evenings |

Each cell opens the full guide for that pair of Sun signs: love, friendship, what works and what breaks.
Questions
Is compatibility by birth date better than by zodiac sign?
It is more exact. A sign only tells you where the Sun was. A birth date gives the Moon, Venus and Mars too, and those decide most of the chemistry.
Do we need our birth times?
No. Two birth dates are enough. With times NEBO adds the Ascendant and is sure about the Moon, which can change the score a little.
What is a good compatibility score?
75% and up is a strong pair, 62% to 74% a good one, 48% to 61% a pair that works with effort. Below that it is hard, not impossible: NEBO shows exactly where it gets hard.
Can I check friends, not just love?
Yes. Friendship is part of every pair score, and the Friends section checks whole groups: who clicks, who argues and who holds the group together.
Two birth dates. One answer.
Takes a minute.
