Weekday Range from a given date

SteelersPitts — Wed, 18 Jul 2018 18:40:44 GMT

Hi All,

I've a table with "run date" field. Can anyone let me know how I can create a date range field?

For example:

If Run date is 7/18/2018 then in the weekday range column I need to show the value "7/15/2018-7/21/2018"

Thank you for all the help!!

Use INTNX function to add/subtract days from the run date.

data w;
k='18jul2018'd;
range=catx('-',put(intnx('WEEK',k,0,'b'),mmddyy10.),put(intnx('week',k,0,'e'),mmddyy10.));
format k mmddyy10.;
run;

You need CATX and the INTNX functions.

The last parameter in the INTNX function is the alignment parameter. That tells SAS to return the beginning of a week or end of a week for example. So setting the interval to 0, means find the first and last of the week with the b/e alignment options.

@novinosrin code illustrates this.

All of these answers are sniffing in the right direction. But you'll need to clarify the problem a bit. What should the result be for these run dates?

7/20/2018

7/21/2018

7/22/2018
