That would be my guess too. I think people's birthdays have a weird pattern (between seasonal stuff that's "natural", seasonal stuff from people trying to conceive to a target birthday, and interesting cultural effects like the Baby Boom and, IIRC, an observable uptick a gestation period after major blackouts and the like, and the weird New Year taxes effect), but I'd bet dates chosen for characters have a wholly different set of stuff affecting them, with choosing for astrological significance or to match the birthdays of famous people. I'd also guess character birthdays have a lot less background noise of actually being mostly random.
