The function INTCK ('MONTH', '1feb2021'd, '31jan2021'd) returns –1 because the first date is in a later discrete interval than the second date. documentation. That is a very confusing way to write a data step. The INTCK function counts intervals from fixed interval beginnings, not in multiples of an interval unit from the from value. Or create a second data step to read the data back in and run your age calculations. If you are moving by the unit that the values are stored in you can just use arithmetic. 6 data _null_; 7 do dt=0 to 3,"01-JAN-1960"d,'01AUG2020'd; 8 put dt= +1 dt date9.
