hi, i have the below dates in months. i want to insert some more dates after the last date (30/04/2021). I mean i want to add dates till 31/12/2026 but not sure how i can do it. Please note that i want the last day of each month. for example, 30/05/2021, 31/06/2021 etc.

Do you have strings looking like dates, or sas dates?

Maybe something like (code is untested):

data want;
  set have end=startLoop;
  output;
  if startLoop then do;
   do until (date = '31Dec2026'd);
     date = intnx('month', date, 1, 'end');
    output;
  end;
run;
