Hi there, I have a sheet that I am using to keep tabs on follow up interviews
in a research project. When the participant is interviewed I have either the
date it occurred or "client withdrawn" or some comment like this, or the cell
is blank.

I would like to count the number of cells with a valid date, without
specifying the date.
I would also be interested in a second formula where I can specify two dates
to count between.

many thanks for your valuable suggestions! (I did search first), Theo
