The free calculation on this page builds your complete Tree of Life, the structure at the heart of decision-making numerology. You get your seven keys right away, the sap that connects them, your innate qualities and your challenges, with no sign-up and no email address. Each key sheds light on one kind of decision; together they give a coherent picture of your personality rather than a list of isolated numbers.
The sap, or life dynamic, is the sum of the triangle formed by your two roots and your trunk. It is not an eighth key but a general orientation that runs through the whole tree.
Two pieces of information are enough: your birth identity, as registered at birth, and your full date of birth. All your given names count, in order, along with your birth surname (for a married woman, her maiden name). An accent does not change a letter's value (É counts as E), but the spelling must be exact: one letter too many or too few changes the result.
Each letter takes a value from 1 to 9 according to its place in the alphabet: A, J and S are worth 1; B, K and T are worth 2; and so on up to I and R, which are worth 9. You add these values, then reduce the total by adding its digits until you reach a number from 1 to 9.
One exception changes everything: the master numbers 11, 22 and 33 are never reduced. They are written 11/2, 22/4 and 33/6, the master number first and its reduction second, never brought down to 2, 4 or 6. For the date of birth, the method runs three calculations (digit by digit, by whole numbers and by reduced components), because a master number sometimes shows up in only one of them. The free calculation runs all three.
Take someone born on 3 October 1980.
All three calculations agree on 22, a master number: this life path is written 22/4. A calculator that kept adding would show 4 and miss the master number. On other dates, only one of the three calculations reveals it: that is why the method runs them all.
No website is the best in absolute terms, but four criteria let you judge one. It shows its method: which letters are worth what, how it reduces. It keeps master numbers instead of bringing them down to 2, 4 or 6. It gives the result without asking for an email address. And it explains where each of your numbers comes from, so you can redo the calculation by hand.
The calculation on this page meets these four criteria: the method and the origin of each key are explained above, master numbers are kept and the result appears with no sign-up. It is free and stays free: the detailed reports are an option, never a condition for seeing your numbers.
