Please try and provide ready made sample data (so a data step creating the table) so we don't have to do this. It's also always good to post some code even if unfinished as this will help us to better understand where you're coming from.

data have;

attrib

have_date length=8 informat=mmddyy10. format=date9.

other_var length=$8

;

infile datalines dlm='.' truncover;

input have_date other_var;

datalines;

03/11/15. Tid

03/12/15. Tid

03/13/15. Tid

03/14/15. Tid

03/15/15. Tid

03/16/15. Tid

03/17/15. Tid

03/18/15. Tid

03/19/15. Tid

03/20/15. Tid

;

run;

data want;

set have;

/* if 1<= (today() - have_date) <=7;*/

if 1<= ('20Mar2015'd - have_date) <=7;

run;
