Sounds like you need to use COUNTIF for the first part ,,,,, e.g. in cell A1
type =COUNTIF(E2:L145,"02/08/09"), should return the number of times this
date shows up in the range ,,, I assume that is what your asking. For Q2 use
the TEXT function ,,,,, e.g. =TEXT(E2,"mmmm") ,, this should return the month
of any given date.

Q1: The number is what I what to get from above function. I wonder if there
is another way to make above function work in a simpler form.

Q2: If I want to add all values in column D whick have a date in the cell
range from E2:P145 within a certain month, how can I correct date from
,"=02/08/09" in to a month range, for instance, in the August month?
