Hi,
I have a dataset that I want to split based on 2 date columns. In this new column, the date for the intervening months should become the last day of that month
Example;
Start date Enddate
03Jan2022 05may2022
Result:
Start date Enddate NewColumn
03Jan2022 05may2022 03jan2022
03Jan2022 05may2022 28feb2022
03Jan2022 05may2022 31mar2022
03Jan2022 05may2022 30apr2022
03Jan2022 05may2022 05may2022
Thanks for your help!
This solution assumes that the values of startdate and enddate are valid numeric SAS date values.
data have;
startdate='03JAN2022'd;
enddate='05MAY2022'd;
run;
data want;
set have;
diff_months=intck('month',startdate,enddate);
do i=0 to diff_months;
if i=0 then newcolumn=startdate;
else if i=diff_months then newcolumn=enddate;
else newcolumn=intnx('month',startdate,i,'e');
output;
end;
drop i diff_months;
format newcolumn date9.;
run;
