Dear SAS Community member, I am now dealing with a challenge that surprised me. Because i thought there was a simple solution for it 🙂 This is the case. In SAS VA i like to caculate a new date by subtracting 6 months. Date - 6months = new date. Steps: First i like to use treatas function to make the date numeric. Then find a formula to subtract 6 months. This formula must take the diffrent numbers of days in the months into account. Question: Is there a formula which i can use in SAS VA which can calculate 6 months? Remarks: I do not use SAS Base. Regards, Lucien
