How the Synastry Compatibility Tool Works

This calculator evaluates compatibility using three main factors:

1. Birth Date Difference

The difference between two birth dates is converted into a compatibility score range, influencing emotional alignment.

2. Zodiac Sign Matching

Each birth date is mapped to a zodiac sign. Certain combinations create stronger harmony, while others indicate neutral or challenging dynamics.

3. Relationship Duration Impact

Longer relationships slightly increase stability scores, reflecting emotional growth over time.

The combination of these factors produces a balanced compatibility overview that blends emotional intelligence with astrological symbolism.
