Hi Barbara,

A bit more detail please.

Does a cell in that column contain many dates or just 1?

If the former, give an example of how you would manually calculate the
production days with say 3 dates in the cell, and how the dates are
differentiated.

If the latter, what signifies a start date and what an end date?

Do start and end dates get included?

Hi,

I have a sheet with a column "Day" where the production date is introduced
for each mouvement (5-1-04; 6-1-04, 6,2,04...) along the year (those days
can
be repeated according to the production).
I need to calculate how many days of production there is by month and by
year.
Can somebody help me????
Tks.
Barbara
