Hello,

 

I use SAS 9.4 and I have a variable "surveydate" (23AUG2011). Its length is 8, formats and informats are date9. and its type is numeric. Does anyone can tell me how to convert it to a SAS date so it shows "18862" instead of "23AUG2011"? I tried the following codes but it does not work.

 

data survey;

set survey;

survey_date=input(surveydate,date9.);

run;

 

Thank you!

It is already is a number, in particular the number of days since 01JAN1960. It only looks to you like it is a date because you told SAS to use the DATE9. format to display it.  Either remove the format or attach different one.

 

data _null_;
   surveydate = '23aug2011'd ;
   put surveydate date9. ;
   put surveydate f9.;
   put surveydate comma9. ;
run;

Thanks Tom! Your codes convert 23aug2011 into 18820 successfully and it is shown in the log.
