Hi @112211, you could use the mod function to to get the remainder from the division of the date (an integer number in SAS) by 7. If the remainder is negative you have to add 7. Each of the seven positive possible remainders correspond to a weekday. 

Hope, this helps.

Best, Markus

Use the MDY function to build the SAS dates. Then either use the WEEKDAY function to retrieve the weekday in numeric fashion, or use the DOWNAME format to display the weekday name.

Please show the code you have tried, so that we can help you improve it.  In addition to the suggestions from others, you might want to use the INTNX function for advancing the date by a year at a time.
