Celtic Tree Calendar (Natal) (凱爾特樹曆命盤)

The Celtic Tree Calendar read as a birth sign — one of thirteen tree-signs from your birth date, each tied to an Ogham letter. IMPORTANT PROVENANCE, stated up front: this is a MODERN system, created by the poet Robert Graves in The White Goddess (1948) from a thirteen-consonant Ogham table in O'Flaherty's Ogygia (1685). It is NOT attested in any ancient or medieval Celtic source, and Graves published it after the leading Ogham scholar of the day warned him the table was a late artificiality. What IS genuine: the Ogham alphabet (c. 4th-6th c. CE), its letter names, the medieval Bríatharogam kennings, and twelve of the thirteen tree glosses, which appear in the 14th-century Auraicept na n-Éces — though that text calls the tree derivation a metaphor and contradicts itself between recensions. What is invented: the thirteen-month calendar, the letter order, the date ranges, Ngetal=Reed, and the entire personality layer (Graves assigned no birth traits at all). The reading therefore gives each sign its Ogham letter, the letter's real philological meaning (only five of thirteen are actually tree words), the attested medieval kenning, and a clearly-labelled modern character read. Dates follow Graves strictly, so 23 December is the nameless day that belongs to no tree. Symbolic modern tradition for reflection, not Celtic history.
