As we learned from the indomitable Emily earlier in the week, September 16th is the most common birthday. It’s relatively easy to figure out why with the judicious application of simple math, the most wondrous of mind-altering drugs.
Average gestation in humans is 38 weeks from conception. That’s 266 days. And what’s 266 days before September 16th? Christmas Eve. Have you ever considered that every single time you celebrate your birthday, in a round-about way you’re just celebrating a specific instance of your parents having sex? In case that wasn’t enough to put disturbing images in your mind, then I assure you that I am confident that every single one of you readers was a toe curler.
So we’ve decided to put together an official Pajiba Guide to Your Conception, in which we rigorously calculate the most likely holiday occasion that led to your eventual mewling birth.
Since the standard deviation is right at a week for length of human gestation, with 75% of births happening in that 38 plus or minus one week region, a two week interval is an effective binning of the continuous function. So go ahead and find the day closest to your birthday below, and Pajiba will explain the holiday you were most likely to have been conceived on and detail the circumstances of your conception.
Now remember, to make the exercise truly scientific, you’ll need to ask your parents if they remember the day in question. And when the mention of Halloween 1978 brings a flush to your mother’s face, you’ll know. When your father gets a distant and hungry look in his eyes when you mention Mother’s Day 1983, you’ll know. For science!
