Partner compatibility
through your chart and theirs
Comparing your birth chart with your partner’s shows what’s really going on between you. We calculate both and find the aspects between them: where the attraction sparks, how each of you shows love, where you click, and where things snag. Venus and Mars have the biggest say.

What partner compatibility shows
We calculate two birth charts, yours and your partner’s, and find the aspects between them (synastry). They show how you affect each other in love: where the attraction comes naturally, how your temperaments fit together, and where the tension builds.
Astra writes the reading in plain language. She goes through attraction and chemistry, your love language and your partner’s, communication, intimacy, strengths, challenges, and concrete ideas for growing the relationship on purpose.
Attraction, Venus and Mars, love languages
For partner compatibility, we look mostly at Venus (love) and Mars (desire and passion):
- Venus to Mars: where the attraction and chemistry between you come from, and what pulls you together.
- Love languages: how each of you gives and receives love, so you understand each other there too.
- Communication and intimacy: how you talk to each other, and what the physical side of the relationship is like.
- No extras: we work with the classical planets. No Lilith, no nodes, so the reading stays easy to follow.
Communication and growing together
Next to attraction, how you talk to each other matters most. The reading shows where you and your partner understand each other easily and where it takes more patience, so a small misunderstanding doesn’t turn into a regular fight.
The ending always looks forward. It doesn’t stop at describing things. It suggests how to grow the relationship on purpose, how to get closer, and what helps in the spots where you two get stuck.
Strengths, friction, and practical advice
The reading names what works naturally between you (strengths) and what’s worth working on (challenges), and it offers a few concrete ideas for approaching each other with an understanding of how each of you is wired.
We name friction plainly, but never as a verdict. If the charts show a strong match, we say that too. Astrology isn’t here to judge your relationship. It’s here to help you understand it better.
How to get it
Partner compatibility is part of the Cosmos plan. You enter your partner’s birth date (required), birth time (if you know it), and birthplace. First name and gender are optional. One partner is included, and you can add another by buying an extra slot. Slots are for life: deleting a saved partner doesn’t free the slot up. You can edit the reading once.
Questions about partner compatibility
›What do I need to enter about my partner?
Their birth date (required), birth time (if you know it), and birthplace. First name and gender are optional. The name only makes the reading feel warmer, and the gender, if you enter it, gently shapes the wording. No last name needed. From these details we calculate your partner’s birth chart and compare it with yours.
›Do I need to know my partner’s exact birth time?
No. If you don’t know it, we use noon as a neutral midpoint and tell you in the reading that the Moon and houses are approximate. An exact time makes the reading more specific, but it still makes sense without one, because Venus and Mars can usually be calculated reliably.
›What does the reading focus on?
Mostly Venus (love) and Mars (desire and passion), along with the Sun, Moon, Mercury, Saturn, and Jupiter. From those we read attraction and chemistry, your love language and your partner’s, communication, intimacy, and how to grow the relationship on purpose.
›Is this fortune-telling? Does it say whether we’ll last?
No. This isn’t fortune-telling, and it doesn’t predict whether you’ll stay together. It describes the dynamic between your chart and your partner’s: where you’re naturally drawn to each other and where things may snag. The future of the relationship is up to the two of you, not the chart.
›Which plan includes partner compatibility?
It’s part of the Cosmos plan, along with the readings for a child and for friends. One partner is included, and you can add another by buying an extra slot. Slots are for life: when you delete a saved partner, the slot doesn’t come back.
›What if the reading doesn’t fit at all?
Astrology names tendencies, not certainties. When something is clearly off, an inexact birth time is often the reason, yours or your partner’s. Treat the reading as a mirror and something to think about, not a final verdict on your relationship.
