The cover of Bayesian Data Analysis 3 shows that empirically, birthdays are not uniformly distributed. The fall has 10-20% more births than other months, and holidays are significantly underrepresented.

Was going to mention this myself. The nuance of this problem is fascinating! Always check your assumptions on the underlying distributions.

I think so. Parents can also make it happen at their convenience by asking doctors. We have technology to induce birth or control its timing over a few days
