Discover the tree that rules your birth. The Celtic Tree Calendar gives a tree, and an ogham letter, to each of thirteen months of the year, every one with its own character, folklore and meaning.
A complete, ground-up rebuild of the original app, pairing brand-new hand-painted botanical artwork with genuine ogham scholarship.

About the Tradition
We tell the tradition straight. The tree calendar was devised by the poet Robert Graves in 1948, not by the ancient druids. But the trees, their ogham letters, and their folklore are genuine, and we cite our sources throughout.
