Hi I am new to Python and not a programmer. I wish to use the field calculator to subtract an "Expiry Date" from the current date. I have used the following code (which works), but it is using a field containing the current date. How do I change this code so it uses only one field and subtracts from the current date? Many thanks Alan Code import datetime def NoDays(d1, d2): c1 = datetime.datetime.strptime (d1.split () [0], "%Y/%m/%d") c2 = datetime.datetime.strptime (d2.split () [0], "%Y/%m/%d") n = (c1 - c2).days return n Expression NoDays( !Expiry! , !Current!)
