There are many hundreds of thousands of date related articles in Wikipedia. The number of articles mentioning February 2 is enormous. To answer trivia such as "who else was born on the same day" you're no worse off searching. (The date article can't hope to list all the people born on that day, and whatlinkshere will be no more informative than a search).
Interestingly, when I was wondering "what value does a date link have" the other night, the only particularly "useful" circumstance I could think of, beyond the obvious case of "articles about holidays etc", was people's birthdays.
