I'm trying to subtract dates, to calculate time duration. I'm
subtracting column A from column B into column C. Column C is
formatted 'm "mos", dd "days"' and columns A and B are formatted
'mm/dd/yy/@' Unfortunately each of the durations is 1 month too
long. That is, if the real duration is 4 days, column C will
display '1 mos, 4 days'

Any clue what I'm doing here?

Thanks much.
