Throughout the year there are so many awareness days, commemorative days, special days, celebrations, holidays, observances, etc, etc. These can be great as blog post inspiration, or just for getting a bit of extra traffic to an existing post by promoting it as a tie-in.
Read on for a list of notable dates for December - if the day has its own website or wiki page, I've linked to it. A lot of the weirder ones are USA based unofficial 'national days'; I've included them in the list if they've crossed the pond, or had a fair number of media hits when I googled them.
