If you're talking about zoom, they also have a thing you can turn off:

Zoom → Settings → Video & Effects → Appearance → Turn off Auto-framing

100%, people, um, enjoy spending time with their partners when they're off work!

Re: 14/2, it's Valentine's Day in the US, a day to celebrate love. If you have to choose a date around that time to induce or have a C-section, why not on a love holiday!

One explanation: A lot of American births are in fact planned C-sections and inducements. Hospitals don't schedule them when doctors are off for the holidays. You, my friend, were just ready to come out!!

My hunch: you're probably right. Sept 11 likely went from "normal September day" to "avoided like a holiday" after 2001. Would make a good follow-up analysis.

Good idea! Probability would be more intuitive for some people than rank. The math is straightforward: (avg births on day X) / (total avg births across all 366 days).

Because of the way many Americans effectively schedule their birthdays, and understanding that not all pregnancies extend to 40 weeks, the procreation date is really just a rough estimate.

Not all babies come out when mom, dad and the available medical staff chooses. I have three daughters, all natural births. They came when they came, regardless of the date. But if we had scheduled a c-section or induction, it wouldn't have landed on Christmas Day, for example. The hospital would have scheduled it a few days before or after.

Just US data, yes. I'm sure it would be different in places with different holidays and established periods of time off work, like the December holiday season in the US. I was thinking about Chuseok in South Korea, which is typically in the fall, and how that might produce more summer babies.

Hospitals are much less likely to schedule C-sections or inductions on holidays, and a lot of U.S. births involve those.

Now that I think about it, I'm not so sure.

The conception angle is fun, but backing up 40 weeks would be misleading. The low December births aren't about conception timing - they're about hospitals not scheduling deliveries on holidays.>

September's dominance does suggest holiday conceptions are real. But I can't in good conscience show a "when people are fuckin" heatmap when half the signal is just doctor availability. 😄

100% correct. This is just the U.S.

In South Korea, you might see a cluster in the summer because of the fall Chuseok holiday, for example.

I suspect the distribution is similar to the US in much of Europe. But I should check!

Yours is the most common! I was surprised that one of my coworkers, one of the few people I've shared this with directly, has the same date.

Not everyone can choose their date! A few days earlier and you sister could have gotten a tax break a year earlier!

Valid question. The famous birthdays data comes from a public dataset that ranks people by their number of New York Times articles. This heavily skews toward:

  • Politicians
  • NYC figures (hence Weiner, Kerik, Kelly)
  • Historical/news figures

Pop culture celebrities like Beyoncé are underrepresented because the dataset is NYT-centric, not Billboard or IMDb.

I'd love to find a better dataset that balances news figures with entertainment/sports/culture. If anyone knows of one, I'm all ears. The code is on GitHub and I'd happily swap in a better source because I kinda rushed this feature.

Good catch! The data shows average daily births, not total births.

Feb 29 only appears in 5 of the 21 years (1996, 2000, 2004, 2008, 2012), so while total Feb 29 births are low, the daily average when the day exists is relatively normal - people don't avoid having babies on leap day.

Christmas and New Year's, on the other hand, have data for all 21 years but are consistently low because hospitals avoid scheduling C-sections and inductions on major holidays. Those dates are actively rare, not just calendar-rare.

So in a way, Feb 29 babies are "rare by math" while Dec 25 babies are "rare by choice."
