When I do this:

DEFINE FILE CAR
NUMDAYS/I10 WITH CAR = DATEDIF('20110501','20110531','WD');
END
TABLE FILE CAR
PRINT NUMDAYS
END

I get 21, but I think I should get 22? But when I do this:

DEFINE FILE CAR
NUMDAYS/I10 WITH CAR = DATEDIF('20110401','20110430','WD');
END
TABLE FILE CAR
PRINT NUMDAYS
END

I get 21, which would be correct. Does anyone know why this function works for April, but not May? Thanks!

Bug perhaps?

Holidays should not count as week days only as business days if you have a holiday file

What do you get if you change the WD to D?

I think you get 30 for May

not correct? sure...May has 31 days...but you should not start at the 1ste of May but at the last day of April

Frank, then why does it work for April.

Actually this is a real bug. Eeker

Pick any month where the 1st starts on a weekend and the answer is -1 day

Yeah, after I posted, I wracked my brain trying to figure it out and realized that when you do datediff, normally you have to put +1 on the end of it (if you want the days of the month). So, if I'm just doing work days, and the last day of the month is a weekend, you don't have to do that... it is inherently done for you. So, in looking at datedif each month from Jan to October of 2011, only April and July are correct b/c they are the only two months that end on Saturday or Sunday. IBI really needs to focus on making functions more user-friendly or at least include this in documentation, IMHO.

If you work for a hospital, you do.
