A synastry reading online compares two birth charts, planet by planet and house by house, to show how two people naturally interact. It highlights where you flow easily, where you may misread each other and how your communication styles differ. To book, you share both sets of birth details and meet online by Google Meet or WhatsApp.

What a synastry reading online compares

"Synastry" simply means placing one chart over another. Western astrologers use the word most often, while Vedic astrology has its own long tradition of comparing horoscopes, including kundli matching. A reading at Karmic Keran works from the Vedic approach but explains everything in plain English.

Planet-to-planet contacts

The first layer is how one person's planets relate to the other's. Your Moon touching their Venus, for example, often describes emotional comfort and affection; your Mercury meeting their Mars may describe lively debate.

Easy contacts and challenging ones

Some combinations describe ease and shared rhythm. Others describe friction, which is not automatically a problem: friction can also mean attraction, growth and honest challenge. A good reading explains both and avoids labelling a match "good" or "bad".

House overlays

The second layer is where one person's planets fall in the other's houses. If your partner's Sun falls in your 4th house, home and belonging may be where you feel their presence most. This shows which areas of life the relationship naturally activates.

Moon signs and nakshatras

Vedic astrology places special weight on the Moon, which describes emotional needs. The Moon's nakshatra (lunar mansion) is central to traditional matching, and comparing the two Moons often explains why one person needs space while the other needs closeness.

What the comparison reveals about communication

For most couples, the practical value lies here. The reading looks closely at Mercury (how each of you thinks and speaks), the Moon (how you feel and recover from upset) and Mars (how you handle conflict). Seeing these side by side can explain long-running misunderstandings in a way that feels neutral rather than personal.

Other lenses used alongside synastry

Chart comparison is rarely read on its own. Two further techniques add context, and knowing about them helps you understand what you will hear in the session.

Ashtakoot, the traditional Vedic score

Ashtakoot, often called guna milan, scores eight factors between the two Moons, such as temperament, emotional rhythm and mutual attraction, to a total of 36 points. It is quick and familiar to many families, but it only looks at the Moon. Synastry fills in the rest of the picture, including Venus, Mars, Mercury and the ascendants.

Each person's planetary period

Two charts can compare beautifully and still meet at a demanding time, for example when one person is in a planetary period that focuses them on career or family duties. Looking at each person's current dasha explains why a relationship might feel different this year from last, without changing what the charts say about your underlying connection.

Mangal dosha and Mars contacts

If Mars is prominent in either chart, a Vedic reading checks whether it is balanced between you. This is handled calmly and in context, never as a frightening label.

Signs a chart comparison would help you

You keep having the same argument and cannot see why.
You are about to take a step together, such as moving in, marrying or starting a business, and want to reflect first.
Your families would value a traditional perspective on the match.
You simply feel curious about why this connection feels the way it does.

Personal reading or online calculator?

Many websites generate an automatic synastry report. These can be interesting, but they list every contact with equal weight and cannot tell which ones matter most in your particular charts. They also cannot answer follow-up questions.

A one-to-one session prioritises. Out of dozens of contacts, usually only a handful genuinely describe your relationship, and the rest is background. You can ask "what does that mean for us?" and receive an answer shaped by both charts as a whole.

How booking and the session work

The Compatibility Reading is a 30-minute, one-to-one session for love or business relationships. It explores strengths, challenges and how you can improve communication and avoid misunderstandings.

Book the reading and choose Google Meet or WhatsApp.
Share birth details for both people: date, time and place of birth.
Note your questions, such as recurring arguments, different life goals or simply curiosity.
Join the session at the agreed time. If you would both like to take part, mention it when you book.

If the other person would rather not take part, see our thoughts on a reading when only one partner is interested.

When a birth time is missing

Planet-to-planet contacts can still be read without exact times, although the Moon moves quickly and may be approximate. House overlays depend on the ascendant, so without a birth time they are left out or offered tentatively. The reading will always tell you which parts rest on firm ground.

Frequently asked questions

Is synastry only for romantic couples?

No. The same comparison works for business partners, friends and family members, with the questions adjusted to the relationship.

Does a synastry reading online feel as personal as meeting face to face?

Most people find a video or WhatsApp call just as personal, and it means partners in different cities, or different countries, can join together easily.

Will the reading tell us whether to stay together?

No. It offers guidance and reflection on how you relate. Decisions about the relationship remain yours.

What is the difference between synastry and kundli matching?

Kundli matching is the traditional Vedic scoring system; synastry is the wider comparison of the two charts. A personal reading draws on both.

To arrange your session, book a Compatibility Reading or send a quick question first if you would like to check anything. Bring both sets of birth details and you will leave with a clearer picture of how your two charts meet.
