Love Compatibility Calculator

Enter two birth dates to compare their Western zodiac signs and get a fun, rule-based compatibility estimate. The percentage is an entertainment score based on a fixed sign-pair matrix, not a scientific measure of relationship success.

How the Love Compatibility Calculator Works

The calculator first maps each birth date to a Western zodiac sign, then looks up the pair in a fixed compatibility table. The same pair always produces the same score, so the result is consistent and transparent.

How to Use It

Enter both birth dates.
Select Calculate.
Review the two zodiac signs and the entertainment score.

Pick both birth dates and select Calculate. The calculator turns each date into a Western zodiac sign and looks up that pair in a fixed table of scores, which run from 50% to 95%. The result shows the score and the two signs. The score is only for fun and has no scientific basis.

Important Note

Astrology compatibility scores are not scientifically validated measures of relationship quality. Use this tool for fun, conversation and entertainment rather than as a basis for important relationship decisions.

How the Compatibility Score Is Calculated

This entertainment calculator first converts each entered birth date into a Western zodiac sign. It then compares the two signs using a predefined compatibility matrix and returns the corresponding score. The same pair of signs therefore produces the same result every time. The score is not a scientific measurement and should not be treated as a prediction of relationship quality. Its purpose is to provide a simple, transparent way to explore zodiac-based compatibility for fun, conversation and general entertainment.

The calculator uses a fixed table with a score for each of the 78 possible pairs of the 12 signs, including a sign paired with itself. The order of the two people does not matter. Only the Western sun sign from each birth date is used, so birth time, birthplace and other chart details do not change the score.

Worked Example

For example, if one birth date maps to Aries and the second maps to Leo, the calculator looks up the Aries–Leo pair in its compatibility table and displays the score assigned to that combination. Reversing the two people does not change the pair, so the same score is returned. A different zodiac sign changes the lookup pair and can therefore produce a different entertainment result.

Worked example: 5 April 1995 is Aries and 1 August 1998 is Leo, so the result is 95%. Swapping the two dates gives the same 95%. Aries with Capricorn (for example 5 January 1990) gives 60%, and two Aries people give 82%.

Love Compatibility Table: Every Zodiac Pair

Each score is the entertainment value this calculator uses for a pair of Western sun signs. The order of the two signs does not matter. Columns use the first three letters of each sign.
