How birthday compatibility works
We take each birth date, reduce it to a numerology life path number, and check whether the two numbers belong to compatible groups. A small date-based factor makes each pair unique. Want just the numbers? Use the Numerology Compatibility calculator.

Frequently asked questions
Can birthdays predict compatibility?
There's no scientific evidence they can. Treat this as entertainment.
What if we share a birthday?
You'll get the same life path number, which numerology treats as a strong match.
Does birth year matter?
Yes. The full date, including the year, goes into the life path number.
