I need to analysis which day of the week flights arrived on time most often and least often.<BR /> <BR /> I am able to pull the numeric day out of the date by using : day=day(date);<BR /> but that is only returning a number. Does SAS know the days of the week based on the date? If so, how do I code?<BR /> <BR /> Thanks!!
