The country's biggest shopping holiday of the year may be around the corner, but drumming up sales between now and Christmas can often be hugely challenging for small businesses. Not only can your more-moneyed competitors afford the door-buster sales that attract shoppers, but they've got much bigger marketing budgets too. Therein lies the beauty of made-up holidays: There's no competition.

When Angie Dudley first dreamed up the cake pop in 2007, few had heard of the cake-and-icing confection that balances atop a lollipop stick. Cupcakes were all the rage back then, says Dudley, who founded the dessert recipe website around the same time. Naturally, she wanted to topple the sweet treat's dominance. So, on February 1, 2008, the Georgia-based baker posted an image of a cupcake-shape cake pop onto a popular cupcake enthusiasts' site. Her icing-and-cake confections took off.

Later that year, she landed on the Martha Stewart Show, and since then, she has published three cake pop cookbooks, one of which has been translated into 10 languages.

"It was viral--but it wasn't like what you see today. Word of mouth was really big," says Dudley, who came to celebrate National Cake Pop Day on February 1. "I'm the one [who] created the craze," she says. "I wanted to have some meaning behind the day."

Still, you may think: Wait a tick, aren't there already a gazillion holidays? And isn't it weird--possibly off-putting--to just coin a new one?

Perhaps, but there is certainly precedence. The International House of Pancakes, better known as IHOP, typically celebrates National Pancake Day on Shrove Tuesday, which this year took place on March 4--even though the breakfast staple has long been celebrated on Sept. 26. Next year, Shrove Tuesday is on Feb. 17--that is the day after Presidents Day and three days after Valentine's Day. The company plans to celebrate the hotcake on March 3 instead. "Those are busy days for us already," says Kevin Mortensen, a spokesman for DineEquity, the owner of the pancake chain. "Sometimes the calendar doesn't line up well."

But that's not stopping people from claiming a free short stack. Since 2006, IHOP has raised more than $16 million for charities and has given away an estimated 26 million pancakes. National Pancake Day also happens to be one of IHOP's biggest sales days of the year, says Mortensen. "It really has taken on a life of its own," he adds.

It hardly stops with pancakes. Besides the 11 federal holidays, Americans observe a long list of religious holidays, feasts, and anniversaries--from Ramadan to Purim. Additionally, each state may have its own variety of local holidays, from Pascua Florida Day, which refers to spring and the Easter Season, to Statehood Day in Hawaii.

And you can't possibly forget the "Hallmark Holidays"--so named for the greeting-card company that popularized the practice of sending cards to loved ones on certain days of the year, like Mother's Day. There are approximately 23 of those.

All told, recognizes 1,100 annual holidays, says Marlo Anderson, the founder of the Mandan, North Dakota-based national holiday tracker. He adds that his site doesn't even cover all of the holidays in existence. "We research [each holiday] and if just six people post [about it] on Twitter, we'll pass," he says. "We don't want to dilute the days we have on there with days that aren't so recognizable."

Still, there is room for more. If you can make a case for why your day ought to be in existence and you can fork over $1,500 to $3,500--the fee National Day Calendar charges for issuing a press release and a 13-by-19-inch framed proclamation--Anderson is all ears. Just ask talk-show host Ellen DeGeneres, who recently snagged her own national day, which also happens to be her birthday, January 26.

"She had a compelling story," says Anderson. "About one year ago, she posted something about National Cat Day saying 'the only thing wrong with this is that I should have my own national day.' It just went crazy," he says. "Hundreds of thousands of people wrote us."

John-Bryan Hopkins from suggests that, actually, it's even easier than that to lasso your own day. And he should know. "I am the guy who has created about 173 of the national food holidays we celebrate today," says the Birmingham, Alabama-based social media consultant who operates the hobby site. While many of the food holidays he tracks--from "National Indian Pudding Day" (November 13) to "National Doughnut Day" (first Friday of June)--were already in existence, he wanted to fete at least one type of food, dish, or cuisine for each day of the year. So, he made some up--including Frog Legs on Leap Day.

To make up a holiday, Hopkins says it's a matter of just putting it out there and doing some coordinated marketing around the day. "If I'm on Twitter and I have 850,000 followers and I get 100 or 150 retweets for a national day post, in the Google database, that day exists," says Hopkins. "Next year, that day is that day."

The question is, how do you turn your holiday into a payday? For starters, consider teaming up, suggests Hopkins. "If I were a little corner shop, I would probably work with other people and get everyone to agree to promote it," he says. "It would be such a shame if you go through the trouble of creating a day that was only for your square block. I would rather the mom-and-pop shops get together."

That's the strategy behind "Green Friday," says Ryan Fox, one of a consortium of marijuana business owners who are rallying behind rebranding the famed shopping holiday Black Friday. The idea is to promote giving the gift of newly legalized marijuana for the holidays.

"We have really high expectations," Fox, the owner of the Grass Station, in Denver, told Bloomberg. "Now we've got the legal means for people to give marijuana as a gift, and that's never really been something that was feasible in the past."

To further confirm the power of fictional holidays, consider the success of Cyber Monday (the Monday following Thanksgiving) and Small Business Saturday (the Saturday following Thanksgiving). The latter was created by American Express in 2010 to gin up sales at the nation's small businesses, and last year it attracted $5.7 billion worth of purchases at independent merchants, according to the financial services giant.

Earlier this month, the Chinese e-commerce juggernaut Alibaba generated $9.3 billion in sales in one day after creating its own shopping holiday dubbed Singles Day. Hard to argue with the point of that holiday, which is for you to celebrate you by buying yourself a gift.

Of course, coming up with your own national day can be tricky. After all, a small business is hardly in the same league as American Express and Alibaba.

"Anyone can attempt to start a day and if it catches on, great," says Anderson. "But it takes a lot of years for this to catch on. Singles Day may be an exception to the rule."

Ultimately, you need to consider what your goals are, suggests Anderson. If you're trying to raise money for charity, for instance, it might make sense to host an event around the end of the year or during a month that holds some kind of significance for the charity or cause. The same goes for triggering sales, he adds.

For Bakerella's Dudley, National Cake Pop Day was a product of wanting to keep her community of cake pop aficionados interested and engaged with the dessert. "It's something to have fun with on social media," she says. "I'll post a photo on Facebook, Instagram and maybe my site. It's a reminder for people to celebrate." And if they want to buy one of her cookbooks, toys and line of cake pop baking tools, that's OK too, she adds.
