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.

George Washington’s Incredible Hair Routine

America's Founding Fathers had some truly defining locks, but we tend to think of those well-coiffed white curls—with their black ribbon hair ties and perfectly-managed frizz—as being wigs. Not so in the case of the main man himself, George Washington.

As Robert Krulwich reported at National Geographic, a 2010 biography on our first president—Washington: A Life, by Ron Chernow—reveals that the man “never wore a wig.” In fact, his signature style was simply the result of an elaborately constructed coiffure that far surpasses most morning hair routines, and even some “fancy” hair routines.

The style Washington was sporting was actually a tough look for his day. In the late 18th century, such a hairdo would have been worn by military men.

While the hair itself was all real, the color was not. Washington’s true hue was a reddish brown color, which he powdered in a fashion that’s truly delightful to imagine. George would (likely) don a powdering robe, dip a puff made of silk strips into his powder of choice (there are a few options for what he might have used), bend his head over, and shake the puff out over his scalp in a big cloud.

To achieve the actual ‘do, Washington kept his hair long and would then pull it back into a tight braid or simply tie it at the back. This helped to showcase the forehead, which was very in vogue at the time. On occasion, he—or an attendant—would bunch the slack into a black silk bag at the nape of the neck, perhaps to help protect his clothing from the powder. Then he would fluff the hair on each side of his head to make “wings” and secure the look with pomade or good old natural oils.

Unwinnable Video Game Challenges You to Keep a Shopping Mall in Business

Shopping malls, once the cultural hub of every suburb in America, have become a punchline in the e-commerce era. There are plenty of malls around today, but they tend to be money pits, considering the hundreds of "dead malls" haunting the landscape. Just how hard is it to keep a mall afloat in the current economy? American Mall, a new video game from Bloomberg, attempts to give an answer.

After choosing which tycoon character you want as your stand-in, you're thrown into a mall—rendered in 1980s-style graphics—already struggling to stay in business. The building is filled with rats and garbage you have to clean up if you want to keep shoppers happy. Every few seconds you're contacted by another store owner begging you to lower their rent, and you must either take the loss or risk them packing up for good. When stores are vacated, it's your job to fill them, but it turns out there aren't too many businesses interested in setting up shop in a dying mall.

You can try gimmicks like food trucks and indoor playgrounds to keep customers interested, but in the end your mall will bleed too much money to support itself. You can try playing the bleak game for yourself here—maybe it will put some of the retail casualties of the last decade into perspective.
