Christmas? New Year’s Eve? Who needs ‘em when you’ve got National Ding-a-Long Day!

Dec. 8: National Brownie Day

As if you need another excuse to eat a sweet treat this month, this holiday is properly celebrated by baking and then devouring a tray of brownies. (You can add nuts if you like.)

Dec. 12: National Ding-a-Ling Day

Get your minds out of the gutter (and your Chuck Berry’s Greatest Hits album). It’s a day to celebrate silly, nutty, goofy behavior by embracing your inner “ding-a-ling.”

Dec. 13: National Ice Cream Day

In 1984, President Reagan officially made July National Ice Cream Month and the third Sunday in July National Ice Cream Day. But there’s always room for more ice cream, so there’s a second National Ice Cream Day, too. (Too bad it’s not the same day as National Brownie Day.)

Dec. 19: Look For an Evergreen Day

That shouldn’t be too hard, what with all the Christmas tree farms, Christmas trees for sale in parking lots, and, if you’re not a Christmas procrastinator, the one that’s up and decorated in your living room. (It’s a great day to go pick out a tree, too.)

Dec. 21: Humbug Day

Named for the catchphrase of notorious Christmas hater Ebenezer Scrooge, the creators of this holiday wanted to give everyone stressed out by the holidays a chance “to vent their frustrations.

Dec. 23: Festivus

Seinfeld writer Daniel O’Keefe wrote into a December 1997 his father’s penchant for celebrating “Festivus,” a non-denominational holiday for those who don’t celebrate Christmas or Hannukah. It’s “a Festivus for the rest of us.” The faux-holiday became a semi-real holiday after the episode aired, with hundreds of people in the real world celebrating as Kramer and Frank Costanza did: with feats of strength, an unadorned aluminum pole, and “the airing of grievances.”
