I'll link to any good things I find of interest for various holidays.
I'll try to keep adding to these as I find them.
Christmas and New Years
Nubeat is a site that has a lot of good Christian music for free and here is their selection of Christmas albums. The first one is my favorite to listen through.
Here you can create your own online advent calendar for family, friends, etc.
An Advent-ageous Epiphany - no particular link here, just to note what has been brought up in our Bible study class about the actually various seasons surrounding Christmas. There is the Advent leading up to Christmas, then Epiphany or Epiphany-tide (Epiphany season) following Christmas. The placement of these times and various dates vary with particular churches ex. Jan. 6 being the traditional date for Epiphany but varies by church tradition.
