(Not as subroutine, but run the program twice)

Thanks Albert. The equation does evaluate day number for each date, then effectively subtracts by using multiplier B=1 for the later date and B=-1 for the earlier date. There is no need to run the program (equation) twice. I would never ask a user to have to run a program twice when one time should suffice.

thanks for commenting,
