A timely move back to the head of my list. Imbolc is the pagan celebration of life returning to the Earth after the "dark days." It is traditionally celebrated on Feb 1st or 2nd. Any of you girls fancy dancing skyclad under the moon in an English winter?
I thought not...

Pale winter sun lingers, lengthening each day,
On twig and branch new buds begin to swell.
Songbirds give voice, each striving to excel,
Seed senses change in its deep bed of cold clay,
Earth goddess weaves her magic to propel
Reborn cycle of her womb along its way


Life returns in every tree’s slow thought,
In pond and stream the dance begins again
Spring flowers show, their purpose to proclaim
A new season comes; winter’s reign is short
And darkness no longer exercises any claim;
Green growth dispels grey moods it brought.
