Numbers can mean more than just math homework or dollars and cents — much more.

One number in particular has long been the cause of unease for millions of people: 13. And there is even a word for their unease: triskaidekaphobia.

How about you? Does the number 13 give you the creeps? If so, you're not alone. Because of this reaction, many and hospitals have no room 13. About 8 out of 10 buildings have no 13th floor. Furthermore, for travelers, row number 13 is not an option on some airlines — it has been left off the seating charts.

Silly

Then, of course, there is , the most feared day of all. It occurs at least once a year. In 2017, two Friday the 13ths haunt the calendar. There will be two in 2018, as well. Many people refuse to conduct business, get married, fly on an airplane or even go to work on this loathsome day, costing an estimated $800 to $900 million in losses every year.

But does this actually prove 13 is unlucky? Or did the number somehow just get a bad reputation?

Fears and phobias such as those mentioned here are called . They make believers cringe and leave nonbelievers with the question, "Why do people believe them?" Superstitions are beliefs in the magical effects — good or bad — that particular actions, rituals, or associations have on the natural world. or making a wish while tossing a coin into a well for good are also common superstitions.

Although superstitions have no real scientific basis, triskaidekaphobia is very real for about 9 percent of Americans. Meanwhile, fear of Friday the 13th, or paraskevidekatriaphobia, the most common superstition of all, affects an estimated (and coincidental) 13 percent of all Americans.

With so many afraid of 13, there must be a reason, right?

Confirmation Bias

Well, yes and no. Psychologists have long known about "confirmation bias." In other words, if you think something bad will happen on Friday the 13th, then you will be more likely to find the bad while ignoring the good that may happen that day. Likewise, if you believe 13 is unlucky, you will notice it whenever it pops up in a worrisome way, ignoring all the other numbers that may be around at the same time.

But all three men on board made it home safely despite extremely difficult circumstances. On the other hand, the preceding mission, Apollo 12, caught fire while on the launch pad, killing all three men inside. That seems much more unlucky and tragic than Apollo 13, doesn't it?

There are several theories as to why we have superstitions. All are based on our inner need to explain what we don't understand. Humans like to look for ways to help us feel like we have control over fate and circumstance. No one likes bad luck, but thinking we can at least predict or avoid it makes us feel a little more comfortable.

Fears of 13 are thought to have been around for a very long time. Some think it began in ancient Babylon; others believe the superstition has its roots in Christianity or the Viking religion. Still others trace its origin to before civilization began, to our early ancestors who tracked the 13 lunar months.

The truth is, 13 has meant different things to different cultures throughout history — fear, praise and indifference. The ancient Egyptians believed it was lucky. In , 13 is considered good fortune, as it is in , parts of India and in the Jewish Torah. And even though measures have been taken to remove the 13th floors, rooms and airline rows, in reality they are still there. They have just been given another number to trick fate. (As if fate could not see through their ploy!)

20th Century Invention

Yet, despite beliefs that triskaidekaphobia began long ago and has been passed down through the centuries, the earliest known reference to Friday the 13th as a dreaded day did not appear until 1913. It is merely a 20th century invention.

Lets face it: Bad things can happen any day. But if they happen on Friday the 13th and you believe its unlucky, then those are the days you are sure to remember.
