Your Celtic birth tree is the tree sign that the Celtic tree calendar assigns to your date of birth. There are 13 signs across the year, each tied to an ogham tree name and a short set of personality themes. It is a modern system rather than an ancient Druid one, but it is a genuinely enjoyable way to read your birthday through tree lore.
This page is the quick lookup. Match your birthday to the ranges below to find your birth tree, then follow the link for the full sign. For the story of where the system came from, see celtic tree astrology. For a deep profile of all 13 signs, see the celtic tree calendar.
How to find your birth tree
Find the date range your birthday falls into. Each range maps to one tree sign. A quick note before you start: these dates are not standardized, so other sites may shift the boundaries by a day or two, and a longer 21-sign variant also circulates. The table below uses the common 13-sign scheme.

What your birth tree is meant to say about you
Each sign is read as a personality type, in the same way a star sign is. Your birth tree is said to shape your instincts, your strengths, and the traps you fall into. The trees themselves are borrowed from the ogham alphabet, Ireland’s early medieval tree script, which is where the names and much of the symbolism genuinely come from.
Treat the reading as a lens, not a verdict. It is a modern tradition built on old tree lore, and it is at its best when it gives you a fresh way to think about yourself rather than a fixed label.
A note on boundary birthdays
If your birthday sits right on the edge of two ranges, you may see yourself in both trees, and different sources will place the cutoff slightly differently. There is no official authority to settle it, because the calendar is a modern creation rather than a preserved ancient record. Read both profiles in the celtic tree calendar and keep whichever fits you better.
Celtic birth tree FAQ
What is my Celtic birth tree?
Your Celtic birth tree is the tree sign assigned to your date of birth in the Celtic tree calendar. There are 13 signs across the year, each named after an ogham tree such as birch, oak, or hazel. Find yours by matching your birthday to the date ranges in the table above.
How do I find my birth tree?
Match your birthday to one of the 13 date ranges above. Each range corresponds to a single tree sign with its own set of personality themes. If your birthday falls near a boundary, check both neighboring trees, since the dates vary slightly between sources.
Is the Celtic birth tree real or ancient?
The tree names are genuinely old and come from the ogham alphabet, but the birth-tree calendar itself is modern. It was created by the poet Robert Graves in the 1940s, not by ancient Druids. See celtic tree astrology for the full origin story.
Why do different sites give different birth tree dates?
Because there is no single official version. The system is a modern one, so various authors have set the date boundaries slightly differently, and a longer 21-sign variant exists alongside the common 13-sign one. Small differences of a day or two at the edges are normal.
