During December, don't try cheating by clicking on a date past the current one (it won't work anyway!).
This advent calendar includes 25 December for those who are still net surfing on Christmas Day, when all the dates will be available. From this date, you can see the whole Advent Calendar. This is also available at full size if your display can take it!
For WWW clients without active map support:
December: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31
This is possibly the first ever on-line
World Wide Web children's Advent Calendar
(although see also
Nonie's Web Page, including an Advent Calendar).
Pointers to other on-line
Christmas fare are welcome.
