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.

Looking to Downsize? You Can Buy a 5-Room DIY Cabin on Amazon for Less Than $33,000

Five rooms of one's own.

If you’ve already mastered DIY houses for birds and dogs, maybe it’s time you built one for yourself.

As Simplemost reports, there are a number of house kits that you can order on Amazon, and the Allwood Avalon Cabin Kit is one of the quaintest—and, at $32,990, most affordable—options. The 540-square-foot structure has enough space for a kitchen, a bathroom, a bedroom, and a sitting room—and there’s an additional 218-square-foot loft with the potential to be the coziest reading nook of all time.

You can opt for three larger rooms if you're willing to skip the kitchen and bathroom.Allwood/Amazon

The construction process might not be a great idea for someone who’s never picked up a hammer, but you don’t need an architectural degree to tackle it. Step-by-step instructions and all materials are included, so it’s a little like a high-level IKEA project. According to the Amazon listing, it takes two adults about a week to complete. Since the Nordic wood walls are reinforced with steel rods, the house can withstand winds up to 120 mph, and you can pay an extra $1000 to upgrade from double-glass windows and doors to triple-glass for added fortification.

Sadly, the cool ceiling lamp is not included.Allwood/Amazon

Though everything you need for the shell of the house comes in the kit, you will need to purchase whatever goes inside it: toilet, shower, sink, stove, insulation, and all other furnishings. You can also customize the blueprint to fit your own plans for the space; maybe, for example, you’re going to use the house as a small event venue, and you’d rather have two or three large, airy rooms and no kitchen or bedroom.

These “Wonder Women” Bingo Cards Feature Amelia Earhart, Greta Thunberg, and 46 Other Inspiring Icons

You could even shout "Wonder Women!" instead of "Bingo!" if you want.

The original numbered version of bingo dates back to 16th-century Italy, but gamemakers have recently begun to realize that there’s no reason the classic game has to be quite so classic. Now, instead of numbers, you can find cards with pretty much any set of images or words you can think of (or you can simply make your own online).

This edition from Laurence King Publishing features illustrations of 48 incredible women who all, in some way, embody the name of the set: Wonder Women. There are sports champions like gymnast Simone Biles and tennis player Serena Williams alongside young living legends like climate change activist Greta Thunberg and education activist Malala Yousafzai. While you might recognize many of the names from history classes—Amelia Earhart and Rosa Parks, for example—or your own iTunes library (yes, Beyoncé is part of this game), others may be unfamiliar. Did you know about Russian cosmonaut Valentina Tereshkova, the first woman in space?

In other words, Wonder Women Bingo is a great way to celebrate your favorite trailblazers and get introduced to some new ones, too. And since the rules are simple—just pick a chip and see if your card has an image to match—it can also double as a learning opportunity for kids.

The illustrations were created by artist Laura Bernard.Laurence King Publishing/Amazon

The game is available for $35 on Amazon and $20 on Laurence King Publishing's website. And if bingo isn’t really your thing (or even if it is), there’s a Fantastic Women card game available for $13 on Amazon, where players try to top each other’s highest-scored cards using ones from their own hand.

While you’re waiting for your games to arrive, learn about 100 women who changed the world.
