Officially, Intck().But in your case, '-' will be sufficient.
data have;
input bday mmddyy8.;
format bday mmddyy8.;
cards;
11/12/87
12/04/56
03/06/79
04/05/94
03/07/99
03/07/99
;
data want;
set have;
ageindays=intck('day',bday,today());
ageindays_=date()-bday;
run;
proc print;run;
I choose to use month/day/year to inteprete your data, although it can be intepreted in other ways as well.
