Who to make a date difference between two different date format?

Hello SAS world!!

I want to calculate difference between two dates, which are in the following formate: "12JUL2012 and 20120711".

I got a date difference as "-20101525", which is utterly wrong. Can someone help me with this problem?

Thanks

You say formats. Can you confirm that date formats are applied to both variables? Make sure it's not numeric with a numeric or datetime format.

What SAS code got you that result?

mindate DEATH_DT Days_to_Death

12JUL2012 20120711 -20101525

data M.Death;
set M.Death;
Days_to_Death = (mindate-DEATH_DT);
run;

It looks like DEATH_DT is a SAS datetime and not a SAS date. Try

Days_to_Death = (mindate-datepart(DEATH_DT));

I suspect that DEATH_DT is actually just a number and not a date at all. If that's true, you could try:

Days_to_Death = mindate - input(put(death_dt, 8.), yymmdd8.);
