How Common Is Your Birthday? An Interactive Map Can Tell You

At some point in their life, everyone counts back from their birthday and tries to figure out what anniversary, special occasion, or other excuse might have happened to their parents nine months before they were born. To make this backtracking exercise easier—and give us the chance to do it for a much larger population—data journalist Matt Stiles created an interactive "heat map" showing the most common birthdays in the United States for individuals born between 1994 and 2014.

Click on the map and you'll quickly notice that July, August, and September are by far the most common birth months. It's no surprise that nine months prior you'll find the dark and rainy period of October, November, and December when—to put it delicately—people have to make their own entertainment.

According to Stiles, "People generally seem to have time for baby-making during their time off. Several of the most common birth dates, in September, correspond with average conception periods around Christmas. September 9 is most common in this dataset, though other days in that month are close. September 19 is second. Following a customary gestation period, many of these babies would, in theory, have been conceived on December 17 and December 27, respectively."

But that's not all we can tell from the chart. When you take into account the fact that some people get to choose their child's birthday because of induced and elective births, they tend to want to stay away from the hospital during understaffed holiday periods.

"The least common birthdays in this dataset were Christmas Eve, Christmas [Day], and New Year’s Day," Stiles concluded. "Dates around Thanksgiving aren’t as common. July 4 is also at the bottom of the list. Conversely, Valentine’s Day ranks relatively high, as you can see in the graphic, as are the days just before a new tax year begins."

Amazingly, though it only comes around every four years, Leap Year babies aren't as uncommon as you might think: February 29 ranked 347th out of 366 on the list.

8 Surprising Uses for Potatoes

Potatoes are one of the world’s most common, and most beloved, vegetables—and they can be used for much more than just sustenance. In honor of National Potato Day, here are a few other ways to use a potato.

1. WEAR THEM

Potatoes come from a nightshade plant called Solanum tuberosum, which blooms with white, pink, red, blue, or purple flowers. In the late 1700s, in an effort to inspire their starving subjects to plant the newly introduced vegetable—which the Spanish had brought to Europe from the New World—Marie Antoinette wore potato flowers in her hair, and her husband King Louis XVI wore them in his buttonholes. This inspired potato flowers to be a favorite of the French nobility for a time, but the ploy didn't work: The lower classes spurned the upper class's efforts to get them to farm the crop. 

2. MAKE ELECTRICITY

If you’re in a lurch, or perhaps a doomsday prepper, start stocking up on potatoes now. With just a few household items—wires, some copper, and a zinc-coated nail—and one of the tubers, you can power a clock, a light bulb, and many other small electronics.

3. GARDEN IN SPACE

In 1995, the potato became the first vegetable grown on the space shuttle. Raymond Bula of the University of Wisconsin spearheaded a project in which five Norland variety potato leaves were propagated in space. Bula’s research group monitored this project from Wisconsin, staying in constant contact with NASA, who stayed in contact with the crew on the space shuttle. When the shuttle arrived home, everyone was pleased to find that the potato plants not only survived the ordeal, but actually grew potatoes.

4. GROW ROSES

Gardeners can insert rose cuttings into a potato, and then plant the entire potato as if it were a seed or bulb. The nutrient-rich potato helps provide moisture and sustenance to the growing plant, giving the cutting a better chance to survive.

5. MAKE PLASTIC

Bio-plastics, as they’re called, can be made from corn, wheat, and—you guessed it—potatoes. The concentration of starches and cellulose in a potato can be used to make plastic, and the plastic made out of potatoes can be burned and composted with much less impact on the environment.

6. MEASURE TIME

Peru’s Incas used the potato for all sorts of things at the height of their civilization. Known for creative, forward-thinking agricultural practices, the Incas also studied time—and started using the time it takes to cook a potato to measure time.

7. REMOVE RUST

Have a knife with some rust spots? If you insert the knife into the potato and let it sit for awhile, you'll go a long way in removing the rust. Potatoes naturally contain oxalic acid, which is used in many household cleaning products (in much greater quantities, of course). Oxalic acid also dissolves rust. To attack larger rusted surfaces with a potato, cut it in half, sprinkle baking powder on it or dip it in dish soap, and get to scrubbing.

8. MAIL THEM

Thanks to Mail A Spud, for only $9.99 everyone’s dream of mailing a potato to their closest friends and family can be a reality. The site advertises that it can send potatoes anywhere in the U.S., and that your choice of mailed gift will be sure to delight recipients. And, if not delight, at least confuse ... in a good way.

Get Paid to Write Dirty Jokes for Cards Against Humanity

If you've exhausted every possible joke combination in Cards Against Humanity, the makers of the game have a new outlet for your wit. Apply to be a contributing writer and you could get paid to write the gross, bizarre, and occasionally offensive cards that go into new editions of the game.

For the uninitiated, here's how Cards Against Humanity works: A player draws a black card, which has a sentence with a section missing from it, and puts it down for the group to see. The rest of the players then put down white cards with words or phrases that could potentially fill in the blank. The player who comes up with the best joke wins the round.

In order for the jokes to be funny, the cards themselves need to be well written. That's where the contributing writers come in. As the job posting explains, the new writers will make $40 an hour "writing poop jokes as needed." The position is remote and part-time.

To see if you're a good fit for the gig, Cards Against Humanity is asking that you submit ideas for 15 white cards and five black cards that best exhibit your humor and writing skills. They've even included a handy primer on "how to write cards that don't blow" for applicants who are unsure of where to start. "A good black card allows players to subvert an expected tone or logic," the guidelines explain, while white cards should have "distinct voice, perspective, or syntax." The page also includes general guidelines on structure and the Cards Against Humanity style.

To apply, submit your ideas through the website before August 31. And if you're looking for some offbeat inspiration, this 19th-century version of the game should kickstart your creativity.
