Convert SAS date

Hi,

Changing date formats are so confusing!

 

I would like help changing a DOB format that is a SAS date, (e.g. 17673) to a meaningful date such as date10. 

 

Thank you!

date= 17673;
date1=put(date,date9.);
date2=date;
format date2 date9.;
put _all_;
run;

dob1=input(dob,???);

format dob1 date10.;

run;

 

THis is the code I am trying to use...but not sure what to put in the ??? if I am working with a SAS date (e.g. 19632)

Re: Convert SAS date

PUT() converts your date from a SAS DATE to a TEXT field.
Applying a format via the FORMAT statement changes how SAS displays the date, ie the underlying value is 19632, but it appears as 01Oct2013. Keeping the date as a SAS date allows you to use all the date functions in SAS in the future, for example, MONTH(), YEAR() to extract portions of the date. As well as it will sort properly in time, whereas if it's a character variable it will sort alphabetically.

Short version: Apply a format, don't use PUT() to convert.

Try the above. Also, please take the time to format your code properly.  

You don't need input unless the value is a character and it seems to be a number.
