Chalica
The holiday first emerged in 2005 out of a wish to have a holiday organized
around Unitarian Universalist values.
Chalica begins on the first Monday in December and lasts seven days.
Each day, a chalice is lit and the day is spent reflecting
on the meaning of that day’s principle
and doing a good deed that honors that principle.
Not all Unitarian Universalists celebrate Chalica, but it has a growing following.
There is a Chalica Facebook page, blog, and many Chalica-themed videos on YouTube."
