You could use the
IF function to
put a 1 or 0 in the next column to determine whether or not to count
this score.
Here's what you can do:
Create two cells in your sheet for a Begin Date and End
Date. I'll put them in D1 and D2 respectively (use any you
like).
Now, if your date is in column A, then you could say in column B:
=IF(AND(A1>=$D$1,A1<$D$2),1,0)
In English, this says "if A1 is after my start date and before my
end date, put a 1 in this cell, otherwise, put a 0 there."
The dollar ($) signs create an ABSOLUTE reference so when you
AutoFill this formula down your row, it stays D1 and D2.
Now, just SUM up that column, and you have a count of all of
the dates that are between your start and end date.
