The Ogham Tree Calendar is based on the Ogham alphabet and its association with trees. It consists of 13 months, each 28 days long, following the lunar cycle, as Roman accounts have suggested the Druids did.
The Tree Calendar’s influences lie within ancient Celtic mythology and folklore.
It is a beautiful example of how modern spiritual beliefs and the customs of ancient times can be combined to form something enchanting.
Each of the 13 months is represented by a tree together with its Ogham letter. Every tree had its own significance in Celtic life and folklore.
