Everything Under the Moon

What are some commonly performed spells at winter Solstice? It coincides with a full moon this year, and on a Friday.

Maybe it's just me but I usually observe the Sabbat and don't do spells at the same time. I keep it simple. It's Kind of a double header with the moon, but full moon can be observed the day before, renewal-of-life spells seem like a good theme just before the rebirth of the Sun.
