Celtic Numerology

The calculator works from your date of birth and your name, plus an optional second birthday. From the date it finds one of thirteen tree signs in the tree calendar popularised by Robert Graves in The White Goddess (1948), a twentieth-century scheme rather than a surviving ancient one. Each sign lists a Gaelic letter name, an animal, an element, a gemstone, a colour and a rune. The runes come from the Germanic futhark, not from any Celtic script, so treat them as a modern cross-reference. Your name produces an ogham number, and a second birthday adds an element comparison.

Ogham is an early medieval Irish alphabet of twenty core letters in four groups of five. The calculator numbers them 1 to 20 in that order, from Beith (B) to Ioho (I), drops accents and spaces, and adds up every letter. English letters with no ogham equivalent borrow a near sound: J and Y count as Ioho, K and X as Coll, V as Fearn and W as Huath. Z counts as Straif, the letter medieval manuscripts transcribe as z, and P, which ogham lacks, counts as Beith. The total is reduced digit by digit to a single number from 1 to 9, with no master numbers kept.

Take Maria Silva, born on 14 March 1990. The page does not ask for gender, so that detail plays no part. Her birthday sits inside the Ash period, 18 February to 17 March, giving Ash (Nion) with the seahorse, Water, coral, pale green and the rune Ansuz. Her name reads M 11, A 16, R 15, I 20, A 16, S 4, I 20, L 2, V 3 and A 16. That comes to 123, and 1 + 2 + 3 gives a name number of 6.

Treat the tree as a set of images to think with, not a label. Notice which parts of the description fit and which do not; the misses can teach you as much as the hits. The letter breakdown often says more than the final digit, because it shows where the weight sits. For Maria, the three letters A and two letters I supply 88 of the 123. The number 6 is usually linked with care and close ties, so it might prompt a look at where your attention goes among family and friends. With a second birthday, the two elements are rated on a five-step scale from Challenging to Excellent. That compares symbols, not people, so use it to open a conversation rather than settle one.

Used this way, the method offers a calm, structured prompt for reflecting on your name and birth season, but it cannot describe your character with authority or tell you what lies ahead.
