How we read your synastry
Two charts, compared honestly.
The two charts
We calculate a full natal chart for each of you — planetary positions, signs and houses — using the same ephemeris math behind every Kaalveda calculator.
The key aspects
Then we compare the charts planet by planet — Sun to Sun, Moon to Moon, Venus to Mars — to find the connections, and the frictions, that matter most.
What synastry can (and can't) say
It's a lens on the dynamic between two charts, not a verdict on the relationship itself. The rest is between the two of you.
Synastry is a way of looking, not a set of rules. It names the dynamic between two charts — what you bring out in each other — and leaves the rest to the two of you.

How it works
Enter both people's details
Full name and date of birth for each of you. Add a birth time and place if you know them — the Moon moves ~12° a day, so those two fields are what make a Moon reading exact rather than approximate.

FAQ
Quick answers.
What is synastry?
+
The Western technique for comparing two people's natal charts. Each planet in one chart is compared to each planet in the other — the connections that form, called aspects, describe how the two of you tend to interact.
Do I need our exact birth times?
+
Not for the free read — date of birth is enough for the core planets. A birth time helps sharpen the detail, but the main picture doesn't need it.
Is this a verdict on our relationship?
+
No. It's a lens on the dynamic — where you naturally align and where you'll need to put in more effort. Real relationships are shaped by a lot more than planets.
Why do you need both people's details?
+
Synastry only works chart-to-chart. We need each person's own birth details to build both charts before we can compare them.
What if the read shows friction?
+
A tough aspect isn't a red flag by itself — plenty of strong relationships carry some friction in the chart. Treat it as a starting point for a conversation, not a final answer.
