SAS DATE- Last Available Day of Each Month

Benn — Sat, 06 Oct 2012 18:39:37 GMT

Hi Guys,

I'm trying to retrieve from my data the last day (not calender day) of each month. However the last day may not be the last day of the calender month, but the last day of the month given my data.

Eg. 20080601

20080627

20080622

20080712

20080729

20100128

20100125

I am trying to get a code to retrieve 20080627, 20080729 and 20109128.

Thanks a lot guys!

You could do it easily with proc sql:

proc sql;

create table want as

select max(date) as last_day format date9.

from have

group by year(date),month(date)

;

quit;

Hi Arthur,

Thanks for the code.

I was wondering if the date can be left in the original format YYYYMMDD. Because the code results in "2008 JAN 01" .

Thanks!

Hi Art,

yymmdd8. doesn't work for me. I changed it to yymmddn8. to get 20080828. Thank you!

Linlin: Then I will change mine as well. As you can tell, it wasn't tested code. Too busy listening to the Michigan State football game.
