Hi:
This is not an ODS or Reporting Procedure question. If you do this:
1) go to
http://support.sas.com
2) click on Samples & SAS Notes on the left
3) When the Samples window loads, type
calculate holiday
into the search box and then click Search
You will get the following hit:
http://support.sas.com/kb/26/044.html
and this note points you to a second example of determining US Holidays:
http://support.sas.com/kb/24/655.html
and that note points you to these 2 links:
http://support.sas.com/kb/24/735.html
http://support.sas.com/kb/25/993.html
AND, there's a Tech Support note about using interval functions:

For more help with this task, your best bet is to contact Tech Support.
