1) 'Tis The Season: "It may be the season to be jolly, but this time of year is also traditionally fraught with hazards involving etiquette, botulism, family and social trauma, economic depression and all sorts of other miseries. Sisters Meg and Anna (not in the nun sense of the word - they're actually related) answer your holiday questions and help you sail through the festive period relatively painlessly."
2) The Advent calendar at harpold.com. A masterpiece of design and content - each day "a happy Christmas memory, a holiday link and something special". And some of those somethings are special. Festive recipes, traditions, decorations and some stunning animations. Check out today's snowfall, for example, these candles, these Christmas lights or this snowman.
3) The Renaissance-style Advent calendar at ILoveFizzyPop. There are far too many advent calendars around these days which have absolutely nothing to do with Christmas. Most of these have pictures of Gareth Gates, Bob The Builder or Barbie on the front, with tiny tasteless slabs of chocolate inside. At last, here's an online calendar which actually remembers the true meaning of Christmas - shepherds, angels, mangers, wise men, Mary, Joseph and all - and then shamelessly subverts the lot of it. My favourite window is definitely December 13 - not that I remember there being any cheese in the original Christmas story.
