Oh, those crazy, hazy days of October silliness.

Allow me to be the first to wish you a happy Mad Hatter Day! Now go do something silly.

Mad Hatter Day isn’t marked on your calendar? You need a new calendar. The year is jammed full of weird, odd, unusual and otherwise quirky celebrations and commemorations not listed on normal calendars.

Among them, Oct. 6 is Mad Hatter Day.

In the original “Alice’s Adventures in Wonderland,” author Lewis Carroll describes the Mad Hatter as having tucked into the headband of his hat a card that reads “In this style 10/6.” It’s the price tag — 10 shillings, six pence.

Disney animators shortened it to a simple “10/6.”

And so, on 10/6 of every year, we celebrate Mad Hatter Day by being offbeat, wacky and nonsensical. Or, as we call it at our house, Tuesday.

October is a strange and colorful month — not quite hot, not quite cold, and full of changing colors, apple cider and candy.

The great philosopher Albert Camus summed up October: “Autumn is a second spring when every leaf is a flower.”

The great philosopher Van Morrison said, “Well, it’s a marvelous night for a moondance … ‘Neath the cover of October skies.”

For the sports fan, the great philosopher Jason Love remarked, “October is not only a beautiful month but marks the precious yet fleeting overlap of hockey, baseball, basketball, and football.”

I’m partial to the month because one gorgeously sunny October afternoon, I married my beautiful bride. My face probably turned more shades of reds, oranges, purples and browns than the vibrant show being put on by the trees outside, but that’s OK. I married my dream girl ‘neath the cover of October skies.

What else can you celebrate in October? Here’s a sampling from the various calendars of unusual holidays:

Oct. 6 — It’s also National Transfer Money to Your Daughter Day. Yeah, nice try, Melissa.

Oct. 7 and Oct. 14 — Bald and Free Day. If you’re shiny on top, say amen. (Why two days? The bald guys got confused and couldn’t agree which day was their day.)

Oct. 9 — Curious Events Day. Just in case you didn’t get it all in on Mad Hatter Day. It’s also Moldy Cheese Day, which is rife with possibilities of ripe practical jokes. It’s also Take Your Teddy Bear to Work Day. I think work would be a nicer place if we took our teddy bears to work every day. And our blankies and pillows. My boss disagrees.

Oct. 11 — It’s My Party Day. It’s also National Fossil Day. So if it’s your birthday and you possess a Golden Buckeye Card or some other such passport to geezerdom, this definitely is your day. I’m thinking of enjoying a bonus birthday celebration myself.

Oct. 13 — International Skeptics Day. Or so they say. I’m not so sure…

Oct. 14 — National Dessert Day. Wait, there’s only ONE day for dessert? I’m growing skeptical again.

Oct. 15 — National Grouch Day. Probably because National Dessert Day is over.

Oct. 19 — It’s both Evaluate Your Life Day and Sweetest Day. Insert your own wisecracks at your own risk. I’m not touching it.

Oct. 21 — We have another double-header — Babbling Day and Count Your Buttons Day. Spend your day counting buttons and you’ll end up babbling.

Oct. 24 — National Bologna Day. Thankfully, this does not pair with Moldy Cheese Day.

Oct. 26 — National Mincemeat Day. As for me, I’m turning the calendar back two days and having a bologna sandwich instead.

Oct. 30 — National Candy Corn Day. Grab it now. There won’t be any left in another day.

And now it’s National I Need to End This Column Day. Have an odd October.
