According to Celtic belief, the date of your birth is connected to the lunar calendar, which can tell you a lot about a person’s personality. They also believed that trees were a fountain of wisdom and represented the universe in their make-up: the roots a symbol for the past, the ever-present trunk a symbol for the present and the branches reaching toward the sky a symbol for what’s to come.

Because of this, they developed the tree zodiac or birth month trees. Each tree corresponds to the lunar months, which means there’s 13 instead of 12.

These small details are a great way to commemorate the birth of your little one, too. You might even find some unique baby name inspo! Read on to find out birth trees by month.
