Roots Calendar

Roots Calendar is a living, breathing alternative to the calendar on your wall.
The calendar syncs with your existing Google Calendar, so your life doesn't stop, it just gets a second layer of meaning.

Based on the Celtic Tree Calendar (Beth-Luis-Nion system), it divides the year into 13 months of 28 days each — each named after a sacred tree, each carrying its own keyword and wisdom.

Beth · Birch · New Beginnings
Luis · Rowan · Protection
Nion · Ash · Connection
Fearn · Alder · Guidance
Saille · Willow · Intuition
Huath · Hawthorn · Cleansing
Duir · Oak · Strength
Tinne · Holly · Balance
Coll · Hazel · Wisdom
Muin · Vine · Harvest
Gort · Ivy · Perseverance
Ngetal · Reed · Healing
Ruis · Elder · Transition

The year begins December 24th — when the Birch starts its cycle. Day 365 is Year Day: a nameless threshold between years, belonging to no month.
