Just a heads-up:
There will be a full moon on January 1st. That is, it will be full enough on New Year's Eve to consider full.
If you want to do anything witchy for the new calendar year, you've got that to work with, too.
I know many people don't pay attention to moon phases until the day-of, so here is some advance knowledge for the sake of any preparations anyone might want to make.
