Celtic Tree Zodiac
13 Druid calendar trees, assigned by birth date — a real tradition from Robert Graves' "The White Goddess," computed live.
Each of the 13 trees governs a fixed date range in the Celtic lunar calendar, from Birch at the winter solstice through Elder at its close. This is the standard 13-sign version most commonly cited today; some later traditions add extra solstice or equinox "in-between" days, similar to how tarot decks disagree on Strength and Justice's order — Synastri sticks to the well-established 13-sign version rather than inventing dates no source agrees on.
Different sources place a handful of these boundary dates a day or two apart. The ranges here follow the version most consistently cited back to Graves' original calendar.
By your birth month and day alone (no year needed) — each of the 13 trees in the Druid calendar governs a fixed date range, from Birch at the winter solstice through Elder at its close. A real, well-documented tradition from Robert Graves' "The White Goddess."
No — three separate systems that each assign a sign from a birth date, using different calendars and different symbolism. The tropical zodiac uses 12 solar signs, the Chinese zodiac uses a 12-year animal cycle, and the Celtic tree zodiac uses 13 trees tied to a lunar calendar.
