SAS DATE- Last Available Day of Each Month

[Benn]

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!

just change the format from date9. to yymmddn8.

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.

Hope they will win the game. I know you graduated there.
