Friday, Nov. 13, 1970: the deadliest tropical cyclone in history, the Bhola cyclone, peters out after devastating Bangladesh, killing an estimated 300,000 people.

Friday, Nov. 13, 1985: more than 20,000 die as the Nevada del Ruiz volcano erupts in Colombia, burying the nearby towns of Chinchilla, and Amerno.

Friday, March 13, 1996: Thomas Hamilton opens fire at Dunblane Primary school near Stirling, Scotland, killing 16 children and one teacher before turning the gun on himself.

A quick look at those headlines may confirm for you relatively quickly why people fear Friday the 13th.

Of course what they don鈥檛 tell you is that with 365 days and billions of human beings to choose from you can pull out a similar handful of tragic headlines for pretty much any Monday the 9th, or Saturday the 25th, too.

The Titanic went down on a Sunday the 14th. Hitler invaded Poland on a Friday the 1st. The Bruins ended Vancouver鈥檚 Stanley Cup dreams on a Wednesday the 15th.

Any rational examination of history shows us that the personal assistants for Mr. Bad Luck and Ms. Fortune don鈥檛 schedule their appearances based on the calendar.

But you can bet your lucky rabbit鈥檚 foot that somewhere today you will encounter a reference to it being a day when you should tread carefully.

鈥淪uperstition is a belief that there is a relation between an action or event when there is none,鈥� Vancouver Island University professor Robert Pepper-Smith said. 鈥淭he psychological mechanism is we want control.鈥�

Friday the 13th comes around . Every year has at least one. 2018 has two (the next is July 13). Some years have three.

Why friggatriskaidekaphobia 鈥� yes there is a word for fear of Friday the 13th 鈥� has managed to embed its clutches on our collective consciousness is a matter of debate and conjecture.

Phillips Stevens, Jr., an associate professor of anthropology at the University at Buffalo, studies the origins of cults, superstitions and cultural identities. In a from the university, he said that Western culture鈥檚 fear of Friday the 13th likely started in the Middle Ages, based on Christian teachings.

鈥淭here were 13 people at the table (at the Last Supper) and the 13th was Jesus,鈥� Stevens said. 鈥淭he Last Supper was on a Thursday, and the next day was Friday, the day of crucifixion. When 鈥�13鈥� and Friday come together, it is a double whammy for people who have these kind of magical beliefs.鈥�

National Geographic echoed that finding in that also pointed to the Norse myth of the uninvited 13th dinner guest sending the world into darkness. That same article said 13 suffers from being after one of numerology鈥檚 favourite sons, the number 12 鈥� 12 months in a year, 12 signs of the zodiac, 12 gods of Olympus, 12 labours of Hercules, 12 tribes of Israel, and 12 apostles of Jesus.

That factors into Western culture鈥檚 lack of thirteenth floors, room 13s, row 13 on airplanes, and dinner parties with 13 guests. Or at least some Western cultures. It鈥檚 Tuesday the 13th that is considered unlucky in Spain, and Friday the 17th in Italy. In Asia, it is the number four that makes people squeamish.

The 1907 Thomas Lawson novel Friday the Thirteenth is sometimes credited for cementing the date into popular culture, something that was reinforced by the long-running Friday the 13th horror movie franchise.

While there is some statistical evidence that people will change their behaviour on that day, experts agree on one thing: there is no correlation between Friday the 13th and bad luck.

The date has certainly has been kind to in the state of Michigan. Kelsey Zachow of Port Huron won $66 million on a lottery drawn June 13, 2014 and Kendall Warren of Kalamazoo won $27 million on May 13, 2011.

So why do people continue to believe?

It鈥檚 a question for the philosophers like Pepper-Smith, who teaches critical reasoning. He said the cultural prevalence of Friday the 13th has people hard-wired to pay attention to bad luck on that day. When it happens, it overshadows everything else.

鈥淕enerally what happens is that event is so memorable all the other Friday that 13ths are forgotten.鈥�

However, for all the lip service the day gets it doesn鈥檛 seem to get in the way of many activities one typically would think as potentially tied to some superstition.

In 2016, the Nanaimo-Ladysmith Retired Teachers Association hosted the grand opening for its archive of unique heritage educational material on Friday, May 13. They chose the date deliberately, as did the Sanctuary Gabriola group, which hosted a beer and burger fundraiser that night to help refugee families.

鈥淚t鈥檚 a date people are going to remember,鈥� Carol Baird-Krul a member of the Nanaimo-Ladysmith Retired Teachers Association said at the time. 鈥淲e鈥檒l treat it as a lucky day.鈥�

A quick call-around to a handful of Vancouver Island lottery kiosks revealed local players certainly weren鈥檛 changing their lottery-buying habits due to the draw date. Ticket sales seem steady and on par with typical Fridays. In fact, people may be less likely to skip a ticket feeling that would be the day their lucky number actually would come up.

BC Lottery Corporation spokeswoman Angela Law said past history indicates there have not been any negative impacts to sales trends for lottery draws on Friday the 13th.

We also talked to two marriage commissioners who were officiating Friday the 13th wedding ceremonies.

That鈥檚 the type of thinking that appeals to Pepper-Smith, even as he sees the charm in letting superstition lead the way from time to time, despite the evidence to the contrary.

鈥淧eople are free to say I reject that, but then they are rejecting rational response,鈥� he said. 鈥淲e conduct our lives according to the quality of our thinking, but at the same time it鈥檚 human, so we鈥檝e got to smile about it.鈥�
