Adventskalender comes from the word Advent and kalender(=calendar. True brainer...). Advent is something we celebrate in Sweden at least, maybe you celebrate it in Gremany as well. (That was a question btw...) It's done like this:
Every sunday before christmass... Well, not EVERY sunday, just the four last... Anyway the four last sunday you pull out your Advents-candlestick (containing foru candles). The first of Advent you light the first candle, have some Coffee and Gingerbread biscuits. The second of Advent you light the first candle AND the second one. You allso have some coffee and Gingerbread biscuits... On the third of advent you light the third candle (and yes, you light the other two as well), and have coffee, Gingerbread biscuits AND saffronbread (with raisins, baked in a certain shape. Normally this is AFTER the 13:th, ie Lucia where you're supposed to eat those saffronsbreads. It tastes quite good. The saffron is pretty expencive though). The fourth of Advent you light ALL of the candles, and have the coffe and the Gingerbread biscuits and some saffronsbread if you like. And you're happy since there's less than a week 'til X-mass. This year Advent started early, just to make it before X-mass (if it would have started in December this year the fourth of advent would have been on boxing day! (We call it Annotherday, sort of. Great when comeing to jokes <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />. Nah, I'll do that another day. Boxing day, perhaps?)).
