How do I convert a DATETIME22.3 value into a SAS date value (number of days since January 1 1960)?  I am running PC SAS 9.3.

The function to extract a date from a datetime is datepart().

So you either do (in a data step)

date_new = datepart(datetimeval);
format date_new yymmdd10.;

or (to replace the original variable)

dateval = datepart(dateval);
format dateval yymmdd10.;

Although I prefer version 1, as it also allows you to set a length for the new variable (date values can be stored in 4 bytes, datetime need all 8).

Thanks for your help. I have copied the code that worked below. rfortin



format newdatadate mmddyy6.; newdatadate = datepart(datadate); d = day(newdatadate); m = month(newdatadate); y = year(newdatadate); sasdate = mdy(m,d,y);
