Assume that birthdays are distributed equally over a 365-day year

That is an incorrect assumption. Certain months have a higher birthrate than others. September usually tops the list.

It’s December, January and February when most of the breeding takes place because winter is cold.

Nine months from December, January and February have the highest birth rates.

Gotta keep warm somehow.
