Fun Facts
Your Life Path Number in numerology is found by adding all the digits in your birth date until you get a single digit. For example, May 15 1990 → 1+9+9+0+5+1+5=30 → 3+0=3.
Zodiac compatibility is heavily influenced by the four elements (Fire, Earth, Air, Water). Same-element pairs like Aries × Leo tend to have natural harmony.
Opposite signs (180° apart, e.g. Aries × Libra) are said to 'attract opposites' and often create exciting, dynamic relationships.
Compatibility tools are just for fun. What truly matters is mutual respect and consistent communication.
FAQ
Q1
What happens if both people share the same birthday?
They'll share the same zodiac sign and life path number. The score reflects a 'kindred spirits' dynamic.
Q2
Can I use this for non-romantic relationships?
Absolutely! It works great for friendships, colleagues, family members — any two-person relationship.
Q3
Does a low score mean we're incompatible?
Not at all! A low score just means a more dynamic pairing. Think of it as 'exciting chemistry' rather than a warning.
