Well, the problem is that I do have the start date listed - but the end date
is blank. I am wanting an average of mowing cycles - I have a start date for
each cycle, but not an end date yet. Is there a way to find the average for
just those with an end date?

How do I exclude empty cells when trying to average columns? I am doing a
large sheet of date differences and want to exclude any empty cells from the
calculations.
