Dear all,

how would I check e.g. "First Saturday in current Month" or "Last Sunday in current Month"? I checked [pre]intnx[/pre] but couldn't find the solution there. With something like[pre]
%if weekday(today()) = 7 and day(today()) lt 8 %then %do;
...
%end;
[/pre]
I could solve this Problem; but is there a "nicer" way?

Thanks in advance,
Thomas

I think that your solution is quite neat, although the NWKDOM function may give an alternative. And to use functions with macro programming, you have to use the %sysfunc macro function.

Hi Linus
What is this "NWKDOM" function? I don't know it and can't find it in the SAS OnlineDoc.
Cheers, Patrick

It is an ETS function that has moved to Base SAS with 9.2. Sorry, should have mentioned it.

Hi Linus,

thanks for your quick reply. Never heard of this function and as we are not using ETS I will have to use my solution.

Thanks and br,

Great! Never heard of "week.2" etc.
This should solve my problem in an elegant way,

thanks,

Dear community,

exactly two years later I have a similar date-Problem: how to determine the last workday (Friday) on or before the 25th? 🐵

Let's assume I have a variable d25cm (25th of current month). I tried with
[PRE]
data _null_;
WDB25=intnx('week.6',&d25cm,(weekday(&d25cm) in (2,3,4,5,6))-1);
if today() = WDB25 then do;
/* more code */
end;
run;
[/PRE]

but that doesn't work as expected. Any idea will be of great help!

With best regards,
Thomas

I think I just found an easy solution (didn't know about the 'weekday' interval):
[PRE]
WDB25=intnx('weekday',d25cm,0);
[/PRE]
