Todd,
 
     The most obvious way is to use the INTNX function with 'year'
being the first parm to the function. However, be careful as this
function will "migrate" a date to the first of the week, month or
year.
 
     A safer bet would be to try something of the following form:
 
    date = date + (intnx ('year', date, 1) - intnx ('year', date, 0));
 
    The two INTNX functions in parentheses will really determine the
number of calendar days in the year of interest and when this amount
is added to your existing SAS date, you will have basically
incremented your year by one.
 
     A second approach would be something of the form ...
 
    date = mdy (month(year), day(date), year(date)+1);
 
Anthony.
