It's mere superstition, right? Bad things befall us when the 13th day of a month lands on the final day of the workweek.
Perhaps not: A folklore historian and founder of the (apparently real) Stress Management Center and Phobia Institute told National Geographic in 2013 that the United States loses an estimated $800-900 million in business on such days.
Folks are, shall we say, reluctant to fly on airplanes or make major house and automobile purchases on an Unlucky Day, whether they self-identify as superstitious or not. Sometimes instances of traffic accidents even dip, thanks in part to an overabundance of caution when people hole up and ride it out on the sofa.
We prefer this tack from English professor Rebecca Borah instead.
"Some people even stay at home -- although, statistically most accidents happen in the home, so that may not be the best strategy," Borah told the magazine in October.
Here are fun events in D-FW where you can enjoy the first of two Fridays the 13th in 2018.
Get out of your house and go to a haunted house
And, if it's true that home is where most unfortunate events occur, you might as well try your luck with the undead instead.
Dark Hour's Spring Fever show features a zombie-themed performance where "the infected swarm in packs and attack while you maneuver through the most hostile environment possible. From fresh dead to rotten, the biters moan and wail, reaching, striving toward the life-blood that fills your veins and the warmth that covers your skin."
Tickets start at $28, and the show runs from 8-11 p.m. on April 13-14 and 20-21.
In Fort Worth, Hangman's House of Horrors will open up its walk-through haunted house attraction ($29) and laser tag hunt for classic movie villains ($39). New for the special occasion is a Crystal Lake-themed overnight campout experience at the Hangman's haunted house, after the attraction has closed ($99-149).
The Crystal Lake campout is for ages 18+ only and features food, snacks, movies and more fun. (Need a tent? The VIP package includes a rental.)
Tickets range from $29-149. Regular attractions run from 8-11 p.m. on April 13 and 14.
Other spooky options:
**Become the Walking Dead at a costume party and concert featuring rock band Sponge at Lava Cantina in The Colony. (Best zombie costume wins $500).
**Go on a ghost tour hike in the woods in Arlington. (This one is family-friendly and includes learning about local legends.)
Or, put Martin House (beer) in your growler for $13
Acheron -- a.k.a. the "river of woe" in Greek mythology -- is a dark, boozy concoction from Fort Worth's Martin House Brewery made with black barley, black malts and chocolate malts. It's aged for 6 months in a whiskey barrel and packs a whopping 12 percent ABV.
On Friday 13, you can fill up a 32 oz. growler of it for a discounted price from 6-11 p.m. at Lone Star Taps and Caps' two locations in Lewisville and Fort Worth. (That deal extends to Martin House's Mind on my Money, as well.)
Other boozy events:
**Go to a costume party with live bands at Division Brewing in Arlington.
**Wander the streets of downtown Dallas on a ghost tour pub crawl.
**Bar crawl for charity in Forth Worth. ($25 admission includes a Friday 13th t-shirt.)
Get pricked (as in tattooed) for good luck
Surely, you know by now: Getting inked on Friday the 13th is tradition, and popular culture dictates that if the design incorporates a 13, it brings good luck.
It's like a tattoo version of a double-negative.
West Dallas: Get high-end ink during a one-night art installation at Erin Cluely Gallery. There will be 13 new tattoo designs by artist Will Heron, the head painter and renaissance man of the Wheron collective. (Surely, you've seen his stunning murals all over North Texas. Perhaps you recall the Dallaxy Pegasus on his now-closed art space, The Platform.) Plus, there will be 13 works of art for sale, a mural installation and an all-female team of tattoo artists.
Tattoos are $30, first-come, first-served, from 6 p.m. to midnight. Here are past Wheron tattoo designs.
People start lining up on Thursday (we recommend heading over on the evening of April 12 and putting your name on a pre-signup list to guarantee your spot for Friday).
Tattoos are $13 with a mandatory $7 tip -- cash only for both.
Deals all over D-FW:
Fresh Ink in Rockwall
Daddy Jack's in Fort Worth (also featuring $13 basic piercings)
Freak Show Studio in East Dallas (you pick the design at random from a bowl!)
Collins Street Tattoo in Arlington
Lucky Horseshoe Tattoo in Fort Worth (with giveaways, plus deals on piercings and smoke pipes)
Hell's 1/2 Acre Tattoo in Fort Worth
Diamond Tattoo Parlor in Hurst (featuring a fire eater! and, tattoo models)
Laugh in the face of unluckiness
Located in the DoubleTree hotel near SMU, Backdoor Comedy hosts a Lucky Friday the 13th Comedy Show for the 18+ set. Tickets are $14 -- unless April 13 is your birthday, in which case your admission is on the house -- and everyone with a ticket gets a prize. Reservations are recommended.
At Pocket Sandwich Theater, it's OK to throw popcorn. In fact, it's encouraged. See Pocket's irreverent take on creepy musical Sweeney Todd for something funny and spooky-light. (Expect "adult innuendo" at this PG-13 show.) Tickets start at $12, and the show runs from 8-10:30 p.m.
Time Warp across days with a midnight screening of Rocky Horror Picture Show at Angelika Film Center -- Dallas. The movie starts at 11:59 p.m. on Friday the 13th. Tickets are $10 and, as always, costumes and audience-participation are encouraged at this raunchy R-rated classic.
Indulge in a Serotonin boost
This free, family-friendly event features samples of chocolate (also free) while patrons stroll and shop local merchants from 5-8 p.m. on the town's historic downtown square.
We like chocolate of all varieties, but be sure to go for the darker variety if you're looking for health benefits like a mood boost, lowered blood pressure and improved blood flow to the heart and brain, according to Livestrong.com.
