https://communities.sas.com/t5/New-SAS-User/How-to-make-one-date-variable-from-three-separate/m-p/690827#M24777 <P>I'm really struggling to make one date variable from three separate variables. For instance, I have "BirthYear", "BirthMonth", "BirthDay" as three separate variables, and I need to make them into one "BirthDate" variable. I'm really lost at how to even start this or what to try. Thank you!</P> Sun, 11 Oct 2020 21:03:08 GMT cass5957 2020-10-11T21:03:08Z https://communities.sas.com/t5/New-SAS-User/How-to-make-one-date-variable-from-three-separate/m-p/690827#M24777 <P>I'm really struggling to make one date variable from three separate variables.
