Using SAS Dates

[Jillian003]

Hi, does anyone know how to reference a time period by adding and subtracting months. For example if the variable is &startdate how would I be able to pull all records 6 months after the date?  6 months before the date?  Thanks!

You can use the intnx function.  e.g., to get all dates before and after &startdate. you could use:

if intnx('month',&startdate.,-6,'same') <=&startdate.<= intnx('month',&startdate.,6,'same');
