Try this for a specific date and the number 1:

A1:A10 = Dates
B1:10 = values

=SUMPRODUCT(--(Dates=DATE(2007,1,1)),--(Values=1))

Change the date as needed.

If you need to count for the date and the number 0:

=SUMPRODUCT(--(Dates=DATE(2007,1,1)),--(ISNUMBER(Values)),--(Values=1))

Better to use cells to hold the criteria:

D1 = some date like 1/1/2007
E1 = 1

=SUMPRODUCT(--(Dates=D1),--(ISNUMBER(Values)),--(Values=E1))

Hi

I am looking if there is a function that can retrive the number of cells
with specific value in one column according to a specific value in another
column. for example:
A table with 2 columns, one for dates and the other is 0 or 1 values. I am
wondering if there is a function that can tell me the number of cells with
the value 1 in specific date.

Thanks in advance

Eli
