Does the score decide whether a relationship will work?

No. The score summarizes harmonious and dynamic aspects, but it is not a certain prediction and cannot replace the real experience of a relationship.

Is the calculation free?

Yes. Planetary positions, cross-chart aspects and compatibility scores are calculated for free.

Astrology Love Compatibility

Q: How is astrology love compatibility calculated?

DailyZodiac calculates the Sun, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto for both dates, then compares the aspects between the two sets of planets.

Q: Do I need the birth times?

No. This first mode uses dates only. It excludes the Moon, rising sign, Midheaven and houses because they depend more strongly on birth time and place.

Compare two birth dates and explore the astrological aspects connected with identity, communication, attraction, stability and mutual growth.

First person

Name or nickname (optional)

Birth date

♡

Second person

Name or nickname (optional)

Birth date

Birth time and place are not required. This mode excludes the Moon, rising sign and houses rather than claiming precision from information we do not know.

ASTROLOGICAL AFFINITY WITHOUT BIRTH TIMES

How astrology compatibility between two birth dates works

Astrology love compatibility, often called synastry, compares the planets of two people. Every planet from the first date is related to the planets from the second date, and their angular distances form conjunctions, sextiles, squares, trines and oppositions. These aspects do not decide whether a relationship will succeed or fail, but they can describe natural affinities and areas that may need more attention.

This version is designed for people who do not know their birth times. DailyZodiac uses a conventional instant, 12:00 UTC, and excludes the Moon, rising sign, Midheaven and houses because they can change with time or depend on birthplace.

Communication

Aspects involving Mercury help describe how ideas, words and mental reactions meet.

Attraction

Venus and Mars highlight affection, desire, initiative and possible differences in how closeness is experienced.

Stability and growth

Saturn is linked with responsibility and limits, while Jupiter and slower planets describe shared expansion and transformation.

What is compared

The calculation includes the Sun, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto for both dates. For each aspect we show the planets, aspect type, orb and score contribution. One aspect can affect several areas when it involves planets with different meanings.

How to read the score

Each area starts from a neutral baseline. Trines and sextiles raise the score, squares and oppositions make it more dynamic, while conjunctions also depend on the planets involved. More exact aspects carry greater weight. The overall score is a technical summary, not a judgment about the real quality of a relationship.

Frequently asked questions

Is this a real synastry calculation?

It is a date-based synastry calculation. It compares aspects between planets that can be used without birth times, but it does not include the Moon, angles or houses. A future complete mode can add them when both times and places are available.

Why is the Moon excluded?

The Moon travels roughly thirteen degrees per day. Without a birth time, its position can change enough to alter aspects and interpretation.

Does a low score mean incompatibility?

No. It only indicates a greater presence of dynamic aspects in this model. Relationships depend on people, choices, context and the ability to communicate.
