How your matches are found

Soulstamp draws on Four Pillars, an ancient astrology from East Asia that reads the year, month, day and hour you were born. It holds that some people’s energies naturally bring out the best in each other.

Your energy

Your birth date carries five energies: Wood, Fire, Earth, Metal and Water. We find the ones that would bring yours into balance.

How their birthday fits yours

Birthdays that bring those energies rise up your list, and so do those where your chart brings what theirs needs. A classic pull for you adds a little more.

Your zodiac animals

We look at whether your zodiac animals get along or clash. Harmony lifts a match, and a clash lowers it.

Why birthdays matter

For centuries, families across East Asia have compared birth charts before a marriage, looking for two people whose energies steady and strengthen each other. Soulstamp brings that same practice to you, reading every birthday in your range against your own.

Each birthday is weighed across its year, month and day, then ranked by how well it balances yours. Share your time of birth and the reading goes a layer deeper. When two birthdays score the same, the earlier date comes first.
