| yesterday | comment | added | Ben Bolker | Diaconis and Holmes discuss this briefly in: Diaconis, Persi, and Susan Holmes. 1996. “Are There Still Things to Do in Bayesian Statistics?” Erkenntnis 45 (2): 145–58. doi.org/10.1007/BF00276787 and Diaconis, Persi, and Susan Holmes. 2002. “A Bayesian Peek into Feller Volume I.” Sankhyā: The Indian Journal of Statistics, Series A (1961-2002) 64 (3): 820–41. | |
| yesterday | comment | added | Nuclear Hoagie | Birthdates can also be particularly non-uniform in certain populations for particular reasons. For example, a population of elite high-school sports players are more likely to have birthdays after the school-year eligibility cutoff date rather than before, since being older within a grade gives a developmental advantage. | |
| yesterday | comment | added | meh | I don't know if birthdays are uniformly distributed, but REPORTING of births is not. likely to be uniform. With Covid data, there was an overabundance of deaths on Mondays as weekend deaths were frequently reported on Monday. | |

| yesterday | comment | added | Greg Martin | Anecdote: I decided to go rogue at the start of a math class I was giving, and described the birthday paradox to my class of 25ish, who agreed to play along. The very first person I called on stated their birthday—and someone else in the class already shared that birthday! I think those two students ended up dating each other :) | |

| 2 days ago | comment | added | Peter Flom | We know that birthdays are not uniform. Major holidays have far fewer births than other days, for one thing. And there is considerable seasonal variation, as well. See e..g how common is your birthday for the pattern in the US. But that's not exactly what you asked. . | |
| 2 days ago | comment | added | COOLSerdash | Just as a general comment: Observed birthdays are not uniformely distributed across the year. Interestingly, the uniform case is the worst-case scenario for the birthday problem: Non-uniform birthdays make it more likely that two persons share a birthday. This is a consequence of the Cauchy–Schwarz inequality. | |
