Celtic Tree Sign Calculator
Modern Celtic tree astrology assigns a tree — Birch, Rowan, Oak, and the rest — from your birth date on the solar year. It’s poetic seasonal lore, not historical druid court record.
This calculator gives you that tree moon with a plain-language read, the same way we surface Celtic identity in the six-tradition home reader.
Tree months on the solar calendar
Each tree spans a slice of the year. Your birthday falls in one tree month; folk interpretations link temperament, craft, and seasonal strengths to that tree.
Frequently asked questions
Is this ancient Celtic religion?
It’s modern Ogham-inspired astrology for cultural learning — not a claim about historic practice.
Does my tree sign change every year?
The tree month is fixed to your birth date on the solar calendar — it doesn’t shift year to year.
