Hello Everyone,

I am trying to find the difference in two dates in number of days. I have dates in numeric format as follows:

Now I want the difference of theses dates from 20161001 in number of days.

Thanks in advance !

SAS has better ways to store dates, instead of using an 8-digit number. If you used SAS's usual methods, you could just code:

difference = '01oct2016'd - mydate;

Given the data you already have, you will need a more complex formula:

difference = '01oct2016'd - input(put(mydate, 8.), yymmdd8.);

How did you import the CSV?

That should be under your control and best practice would be to read it in as a date.
