Here are some holidays and other special days that kids might be interested in but that probably didn’t make the cut on your 2013 calendar:

January

7: Old Rock Day. Perhaps today you could start (or add to) a rock collection.

20: Inauguration Day. President Barack Obama will be sworn in to a second term as president. Because the 20th falls on a Sunday, the public ceremony will take place on Jan. 21 on the steps of the Capitol.

23: Measure Your Feet Day. Are both your feet the same size? Bet you never thought to find out.

February

10: Chinese New Year welcomes in the Year of the Snake.

13: Get a Different Name Day. So if you really hate that Mom and Dad named you Buford T. Rex III, today’s the day to do something about it.

23: International Dog Biscuit Appreciation Day. We suspect this is mostly celebrated by dogs.

March

6: Oreo cookies were sold for the first time in 1912. Have a Double Stuf to celebrate.

14: It’s Pi Day. Not as in apple or cherry. As in the number: 3.14.

April

3: The first ice cream sundae was invented in New York 120 years ago today.

25: World Penguin Day.

30: National Honesty Day. If we’re lying, we’re dying.

May

18: It’s International Museum Day.

June

6: National Yo-Yo Day.

25: It’s Leon Day. “Leon” is “Noel” spelled backward. It means that it’s only six months till Christmas.

July

8: The Liberty Bell cracked while being rung on this day in 1835.

19: Stick Out Your Tongue Day. Just make sure you explain this to whomever you’re sticking it out at.

20: Moon Day, marking the 44th anniversary of Neil Armstrong becoming the first person to land on the moon.

August

1: Respect for Parents Day. This really should be every day, but we know you know that.

20: World Mosquito Day. We’re not sure if this means you should love one or swat one.

September

5: National Cheese Pizza Day.

19: Talk Like a Pirate Day. Ahoy, matey!

October

1: It’s Homemade Cookies Day and World Vegetarian Day, so why not make (and eat) oatmeal raisin cookies in honor of both.

15: National Grouch Day. But that doesn’t mean you have to be one.

28: The Statue of Liberty was dedicated on this day in 1886.

November

15: Pack Your Mom Lunch Day. Be sure to include something sweet.

17: It’s Homemade Bread Day and Take a Hike Day, so pack some sandwiches and hit the trail.

December

1: Eat a Red Apple Day. If you prefer yellow apples, we think that’s OK.

13: National Cocoa Day. We feel warm and toasty just thinking about it.

31: New Year’s Eve. We’ve made it through another year.
