Date variable change from character to date

AnneLK — Wed, 26 May 2021 07:08:51 GMT

I have a data set "hvid11", imported from a RedCap database as excel originately.

I imported it and now one of my date variables (debutskopi_date) is defined as a character with values around 41000 in stead of a date.

My goal was to change is so the dates have the format "MM/DD/YYYY"

I tried to change it to a date variable using this code:

Data hvid11; set hvid11;

debutskopi_date2= input(debutskopi_date,anydtdte32.);

Format debutskopi_date2 ddmmyy10.;

Run;

But the output variabel debutskopi_date2 has wrong dates.

The years in the dates should be between 2013 and 2020, but is in stead between 1940 and 1944

Any suggestions will be greatly approciated.

Best regards Anne

You imported this from Excel, and because of some funny values in the column you got the raw Excel values as character. Do this:

debutskopi_date2= input(debutskopi_date,32.) + '30dec1899'd;

to correct for the different offset in SAS vs. Excel.
